FOREWORD.

The Department of Industrial Relations.

The act of the Eighty-fourth General Assembly, known as House Bill two hundred forty-nine, found in 109 Ohio Laws at page 105, became effective on July 1, 1921.

This law provides for the reorganization of the executive department of the state government and is an administrative code centralizing related executive functions and activities for better administrative care and control.

All duties, rights, liabilities, authority and privileges relating to MINES and MINING, formerly had and exercised under the law by THE INDUSTRIAL COMMISSION OF OHIO, was, by the above mentioned law, conferred upon and imposed in THE DEPARTMENT OF INDUSTRIAL RELATIONS to be administered by the Director of Industrial Relations.

This pamphlet contains all the provisions of the General Code of Ohio directly relating to MINES and MINING, their operation, control and management, put into convenient form for the information and guidance of employers, employes and the general public, for whose benefit and observance they have been enacted.

In any section of the law herein given where the phrase "Industrial Commission" or "The Industrial Commission of Ohio," or "Chief Inspector of Mines" is found, the phrase "The Department of Industrial Relations" is to be read, because such department has, by the law first above mentioned, been given the powers and duties before had by such commission.

All the statutes printed in this pamphlet are in full force and effect.

The Department of Industrial Relations,

WILLIAM ROBINETT, Chief, Division of Mines.

Sec. 905. Repealed. H.B. 249—Sec. 3, 109 O.L.; 105. (Salaries and expenses of inspectors.)

Sec. 906. [Duties of chief inspector.] The chief inspector of mines shall designate the counties, or portions thereof, which shall compose the different districts, and may change such districts whenever in his judgment the best interests of the service so require. He shall issue such instructions, and make such rules and regulations for the government of the district inspectors of mines consistent with the powers and duties vested in them by law, as will secure uniformity of action and proceedings throughout all the districts. The chief inspector of mines may order one district inspector of mines to the assistance of any other, or may make temporary transfers of district inspectors of mines, when, in his judgment, the efficiency of the service demands or permits, and with the consent of the governor, may remove any district inspector of mines for reasonable cause. The chief inspector of mines shall give such personal assistance to the district inspectors of mines as they may need, and make such personal inspection of the mines as he deems necessary and his other duties permit.

(Sec. 909.)

Sec. 914. [Duties of chief inspector and oil and gas well inspector.] The chief deputy inspector of mines and the oil and gas well inspector shall designate the townships in the various coal producing counties of Ohio, which shall be considered coal bearing or coal producing townships, to be included under the regulations as prescribed in section 973 relating to the mapping, drilling and abandonment of oil, gas or test wells. The chief deputy inspector of mines shall allow all matter pertaining to the mapping and drilling of oil and gas wells to be under the direct supervision of the oil and gas well inspector, except when wells are to be drilled, or have been drilled directly adjacent to some mining operation, or in case any arrangement for the drilling of an oil or gas well must necessarily be made in mutual understanding and consideration with some mining operation, or whenever the proper protection of the coal deposits is in question.

The oil and gas well inspector shall supervise the granting of permits to drill or abandon a well, the filing and reprinting of maps of oil, gas or test wells, and see that all the provisions relating to the mapping, drilling, and abandonment of such wells are strictly complied with. In any case where the plugging method as outlined in section 973 cannot be applied, or if applied, would be found ineffective in carrying out the intended protection, which the law is meant to give, the oil and gas well inspector may designate the method of plugging to be used, in all such cases causing the abandonment report to show the manner in which the work was done.

The oil and gas well inspector shall designate the counties or townships thereof which shall compose the different districts of the respective deputy oil and gas well inspectors, or change such districts whenever in his judgment the best interests of the service so demands.

This shall not prevent the attendant from performing other duties, provided the door is not kept open longer than is necessary for cars to pass through. Where necessary, a refuge place shall be provided at each door for the safety of the attendant. (Sec. 943, 958; Penalty, Sec. 976.)

Sec. 924. [Ventilation of mines while persons working therein.] At each mine where the ventilation is not continuous, it shall be started a sufficient length of time prior to the appointed time for any person, or persons, working therein to enter, to clear the mine of explosive, poisonous and noxious gases, and shall be kept in operation a sufficient length of time after the appointed time for such employes to leave their working places, for all persons to be out of the mine. (Sec. 922, 923, 952; Penalty, Sec. 976.)

[Pressure gauges.] At each mine generating fire-damp so as to be detected by a safety lamp, and wherein twenty or more persons are employed, a recording pressure gauge for the purpose of recording the pressure or vacuum of the main air current, shall be provided and maintained, which shall be kept in constant use, and records preserved for ninety days, subject to the inspection of the chief inspector of mines and the district inspector of mines.

Breakthroughs between entries, except as hereinbefore provided, shall be made not exceeding sixty feet apart. Where there is a solid block on one side of a room, breakthroughs shall be made between such room and the adjacent room not to exceed sixty feet apart; where there is a breast or group of rooms, a breakthrough shall be made on one side or the other of each room, except the room adjoining said block, not to exceed forty feet from the outside corner of the breakthrough to the nearest corner of the entrance to the room, and on the opposite side of the same room a breakthrough shall be made, not to exceed eighty feet from the outside corner of the breakthrough to the nearest corner of the entrance to the room, and thereafter breakthroughs shall be made not to exceed eighty feet apart on each side of the room. No working place, except those provided for within a distance of four hundred feet of the principal openings of a mine, shall be driven more than eighty feet in advance of a breakthrough or air-way. The required air current shall be conducted to the breakthrough nearest the face of such entry or room. All breakthroughs between entries, and when necessary between rooms, except the one nearest the working face, shall be closed and made air-tight by brattice, trap doors or other means, so that the current of air in circulation may sweep to the interior of the mine. Brattices between permanent inlet and outlet airways shall be constructed in a substantial manner of brick, masonry, concrete, or non-perishable material. In mines generating fire-damp, so as to be detected by a safety lamp, the air current shall be conducted by brattice, or other means, near enough to the working face to expel the fire-damp, and prevent the accumulation of the same. (Penalty, Sec. 976.)

Sec. 927. [Safe appliances for hoisting persons.] The owner, lessee or agent of a mine shall provide and maintain safe appliances, approved by the district inspector of mines, for the ingress and egress of persons in each shaft, designated by such owner, lessee or agent as a means of ingress and egress for persons employed therein. When there is but one shaft available for ingress and egress from any unavoidable cause, the appliances therein shall be kept available to persons therein employed at all times. When such appliances in any shaft are rendered unavailable from any cause, the same shall be restored without delay.

[Emergency appliances.] When the only means of egress is by vertical shaft, in which cages or elevators are used as a means of hoisting persons therein employed, and the power for operating same is derived from but one source, the owner, lessee or agent shall provide and keep on hand for use in the event of an accident to the hoisting apparatus or the power by which same is operated, a suitable windlass, capable of hoisting the persons from the mine.

[Competent engineers.] The owner, lessee or agent of a mine worked by a shaft or slope, shall put in charge of an engine used for lowering into or hoisting out of such mine persons employed therein, only experienced, competent and sober engineers. (Sec. 916, 928; Penalty, Sec. 976.)

Sec. 928. [Metal speaking tube and safety appliances.] The owner, lessee or agent of a mine operated by shaft, shall provide and maintain a metal tube suitable for conversation between persons, connecting the engine room with the top and bottom of such shaft; an approved safety catch, a sufficient cover, and rings or other adequate handholds for ten persons, on all cages used for lowering and hoisting persons: Such cages to be protected on each side by a boiler plate not less than one-fourth inch in thickness, and not less than three feet high, and shall provide an approved safety gate at the top of each shaft, an adequate brake to control the drum used for lowering or hoisting persons in shafts or slopes, and an indicator on all machines used for such purpose, to show the location of cages in shaft or slope. No cage having an unstable or self-dumping platform shall be used for the carriage of persons unless such platform is securely locked. (Sec. 916, 927; Penalty, Sec. 976.)

Sec. 929.

When regular height is less than six feet six inches from top of rail, the lower side of trolley wire must not exceed six inches from the roof or cross-timber with hangers now in use, with hangers not to exceed twenty-five feet between centers, and the tension sufficient to keep all wires from sagging and to prevent trolley wheel from coming in contact with roof or cross-timbers. All new hangers hereafter installed shall not exceed five inches in depth from lower side of the trolley wire to the roof or cross-timbers.

[Wires crossing traveling ways.] All trolley and positive feed wires crossing places where persons or animals are required to travel, shall be safely guarded or protected from such persons or animals coming in contact therewith.

[Wires opposite rooms and refuge holes.] All trolley and positive feed wires shall be placed on opposite side of track from refuge holes or necks of rooms.

[Bare wires; when not to extend into working places.] No trolley wire shall be extended into or maintained in any room while being used as a working place; no trolley or feed wire shall be extended into any entry beyond the outside corner of the last breakthrough.

[Switches and circuit-breakers.] Switches or circuit-breakers shall be provided to control the current at the mine, and at all important points in the mine.

[Machine feed wires and insulators.] All machine feed wires shall be placed as near the rib and roof or cross-timbers as practicable; the positive wire to be carried not to exceed three inches from the rib and roof or cross-timbers, measured at the insulators, which shall be so placed as to keep the wire at least six inches outside of the track rail on the side the wire is located. Insulators shall be placed not exceeding fifty feet apart, and all wires shall be carried so that same will be not less than six inches outside of the track rail at any point on the side the wire is located. All positive wires shall be carried on glass or porcelain insulators, or insulators equally efficient. All negative wires shall be carried on suitable fixtures, and when carried in same entry as the positive wire, shall be carried on the same side of the entry as the positive wire, and as close to it as practicable. When machine or feed wires are carried in same entry as trolley wire, they shall be placed on the same side as the trolley wire, between trolley wire and rib. Nothing in the foregoing shall require negative wires being carried in same entry with positive wire.

[Wires in shafts or slopes.] When necessary to carry wires down shafts or slopes used as travelways, the wires must be thoroughly cased or protected, so that persons cannot be shocked therefrom.

[Wires; how placed in rooms.] Positive machine feed wires, when extended into rooms, shall be placed not nearer than four feet of the track, where the room is of sufficient width, and the same shall only be connected to the positive wire or wires on the entry while in actual use. The material used for making such connection shall be of sufficient length to reach across the entry, and when same is disconnected, it shall be kept with the machine operating at such point or working place. No electric wires shall be extended into any room unless a one hundred and fifty foot cable will not reach the face of the room, and then not beyond the outside corner of the last breakthrough.

[Protection of terminal ends.] All terminal ends of positive wires shall be guarded so as to prevent persons inadvertently coming in contact therewith.

[Connection of negative wires, pipe lines and track. Bonding of track.] The bonded track, the negative wires and metallic pipe lines, when coming near each other, may be connected together at intervals not exceeding five hundred feet, and any track used as the return or earth system shall be properly bonded. In no case shall a pipe line, or any part thereof, be used exclusively as the return, and when connected to the earth system, the negative wire or bonded track shall be of ample capacity, exclusive of the pipe line, to carry the current.

[Trolley wires; how erected.] The trolley wire shall be carried upon hangers or other fixtures which will properly insulate it from contact with the roof or other substances, and so the trolley wheel can trail without the necessity of being constantly attended for that purpose, and no trolley shall be run on any wire not so carried.

[Locomotive must not be operated improperly.] No locomotive shall be operated by means of a person holding and sliding upon or frequently making contact with the positive wire with any device attached to the cable as a substitute for a trolley, but these provisions shall not prohibit the operation of a locomotive by means of a cable without the use of the trolley, provided the cable be connected to and disconnected from the positive wire when the locomotive is not in motion.

[Protection to machine cable crossing entry track.] Means shall be provided by which machine runners may readily carry the machine cable from the machine to the feed wires on one side of the entry, either under or over the track rails, in the entry where such wires are located, and so the cable will not come in contact with such track rails, thereby reducing the danger of shock to persons or animals required to travel such entry, to the minimum. (Sec. 911, 948; Penalty, Sec. 976.)

Sec. 948. [Voltage at mines hereafter electrically equipped.] The owner, lessee or agent of a mine at which electricity with a pressure or potential of more than three hundred and twenty-five volts, or alternating current, is used, shall in addition to the provisions of the preceding section, observe the following:

[Limit to voltage in or about working places.] At each mine equipped with electric power after the passage and approval of this act, the current used to operate gathering locomotives, mining machines, shearing machines, drills and other machinery, used in or about the working places of the mine, shall not exceed in pressure or potential, three hundred and twenty-five volts, direct current, as shown at the nearest switchboard, and the wires conducting the power from the nearest switchboard shall not carry a higher pressure or potential.

[Relating to alternating current.] At each mine equipped with electric power alternating current may be used to convert alternating current to direct current, and to operate motors permanently installed above ground and in underground substations, or buildings especially prepared for them, in a manner subject to the approval of the chief and district mine inspectors, but no wires carrying alternating current shall be used underground except same be carried in an entry or passageway where persons and animals are not permitted to travel.

[Relating to higher voltage mines hereafter equipped.] At each mine equipped with electric power after the passage and approval of this act, when the current used to operate haulage locomotives, pumps and other machinery not located in or about the working places of the mine, is of a pressure or potential in excess of three hundred and twenty-five volts, direct current, the entry or passage way where such wires are carried shall not be designated or permitted to be used as the principal traveling way, and when designated or used as the escapement way, the wires shall be protected so that persons required to travel near same in emergencies will not inadvertently come in contact therewith. No pressure in excess of six hundred and fifty volts at the switchboard shall be used underground.

[Relating to higher voltage, mines heretofore equipped.] At each mine equipped with electric power prior to the passage and approval of this act, where the pressure or potential is in excess of three hundred and twenty-five volts, direct current, or where alternating current is used, and the conditions surrounding the use of same are such, in the opinion of the chief inspector of mines, that the provisions of the preceding section do not provide the required protection from shock to persons employed therein, such additional safeguards shall be employed as may be required by the chief inspector of mines, and the district inspector of mines, jointly. (See. 911, 947; Penalty, Sec. 976.)

Sec. 949. [Relating to construction of new mines.] Any person, firm or corporation beginning the opening of a mine, whether such person, firm or corporation be the owner, lessee or agent of the property upon which such mine is located, or not, shall observe the following in the construction of such mine: If the opening be a slope or vertical shaft, no explosive used therein shall be fired by means of a squib or fuse after the same is extended more than twenty-five feet from the surface, and thereafter and until the slope or shaft reaches the seam, and the entry or landing be extended beyond a breakthrough or other place driven at right angles thereto, no explosive shall be fired except by means of an electric battery operated from the surface after all persons are on the surface. A substantial structure to sustain sheave wheels or pulleys, ropes and loads, shall be provided, and if the opening be a shaft, the same shall be placed at a height of not less than twenty feet above the tipping place. A landing platform shall be arranged in such manner that no material can fall into the shaft while the bucket is being emptied, and in no case shall the shaft be sunk to a depth of more than thirty feet without such structures. If the bucket used for hoisting material is to land on a truck, the track on which said truck is operated, and the platform, shall be so constructed that material cannot fall into the shaft. Rock and coal shall not be hoisted from a shaft or slope except in a bucket or cage attached to the rope by a safety hook, clevis, or other safe attachment, and the bucket or cage securely locked so that same cannot tip or empty while being hoisted. The rope shall be fastened to the side of the drum, and not less than three coils of rope shall always remain on the drum. After the shaft reaches a depth of one hundred feet, the same shall be provided with guides and guide attachments, applied in such a manner as to prevent the bucket from swinging while being lowered or hoisted, and said guides and guide attachments shall be maintained at a distance of not more than seventy-five feet from the bottom of the shaft. The sides of all shafts shall be properly secured for safety, and no loose rock or material shall be allowed to remain on any timber in the shaft after each blast. All loose timber, tools, and materials, shall be kept away from the top of the shaft, so as to reduce the danger of same falling down the shaft. Where explosive gas is encountered, the person in charge shall see that the shaft or slope is examined before each shift of men enter to work, and before the men descend after each blast. Provision shall be made for the proper ventilation of the slope, or shaft, so that persons working therein will have the necessary air. An efficient brake shall be attached to each drum of an engine used in hoisting material and persons, and all machinery, ropes and chains connected therewith shall be carefully examined once each twelve hours. Not more than four persons shall be lowered or hoisted in or on a bucket at one time, and no person shall be permitted to ride on a loaded bucket. The bucket used in lowering or hoisting persons shall be equipped with proper safety devices, so that same cannot become detached from the rope or cable, and cannot tip or turn upside down while being so used. The chief inspector of mines, and the district inspector of mines, shall have jurisdiction over such mine when the shaft or slope reaches a depth of twenty-five feet, and such person, firm or corporation shall comply with any order issued by either or both of them with respect to the safety of persons employed. Other than the provisions herein, the provisions of this act shall not apply to the opening of a mine until such opening reaches the seam, and the entry or landing be extended beyond a breakthrough, or other place driven at right angles thereto. (Penalty, Sec. 976.)

Sec. 950. [Additional openings; when and how provided for.] When in the opinion of the district inspector of mines together with the chief inspector of mines, the ways and means of egress in any mine under their jurisdiction, from the interior working places to the surface, as provided for in this act, are inadequate as a safe and ready means of escape in case of probable emergency, and there are extra hazards of a permanent nature that cannot be removed either from long distance from the interior working places to the exterior openings for egress, from danger of fire at any point, or any other cause that probably will result in the entombment of persons working therein, they shall jointly give notice in writing to the owner, lessee or agent of such mine, and require an additional opening by shaft, slope or drift, from the surface; the location of the interior end of such shaft, slope, or drift, to be sufficiently near the interior working places in that part of the mine where such persons are endangered, to afford such persons safe and ready means of escape, free from such hazards. (Sec. 932; Penalty Sec. 976.)
