1567.09 Ventilation of mines.

The operator of a mine shall provide and maintain the necessary artificial means of capacity and power capable of supplying the required ventilation, and shall maintain a sufficient volume of air, not less per minute than one hundred fifty cubic feet for each person measured at the point in the mine where distribution to the various working sections begins and distributed to the working faces so as to expel or dilute and render harmless, explosive, poisonous, and noxious gases. The air shall be measured at the last entry break-through in each working section to see that a sufficient volume of air, not less than nine thousand cubic feet per minute, is being distributed at such point, provided that in gaseous mines the volume of air maintained for each person shall be not less than two hundred cubic feet per minute measured at the point in the mine where distribution to the various working sections begins.

No more than sixty-five workers shall be permitted to work on one continuous current of air or split of air except with the written consent of the chief of the division of mineral resources management, and in no case shall the number of workers exceed ninety.

Air in which workers work or travel in mines shall be improved when it contains less than nineteen and one-half per cent oxygen, or more than one-half of one per cent carbon dioxide, or is contaminated with noxious or poisonous gases. If the air immediately returning from a split that ventilates any group of active workings contains more than one per cent methane, as determined with a permissible flame safety lamp, by air analysis, or by other recognized means of accurate detection, the ventilation shall be improved. If the air immediately returning from such a split contains one and one-half per cent methane, the employees shall be withdrawn from the mine or the portion of the mine affected thereby, and all power shall be cut off from such mine or portion of the mine until such dangerous condition has been corrected. If the air immediately returning from such a split contains one and one-half per cent or more of methane, but not more than two per cent of methane, withdrawal of the employees from such mine or portion of the mine and shutting off all power from such mine or portion of the mine shall not be required if all of the following requirements are met:

(A) The volume of air provided and maintained in such split is equal to or in excess of eighteen thousand cubic feet of air per minute;

(B) Only permissible electric equipment is used;

(C) The air does not pass over trolley or other bare power wires;

(D) An official certified under this chapter and Chapters 1561., 1563., and 1565. of the Revised Code is continually testing the gas content of the air during the mining operations therein.

At working faces and other places where methane has accumulated and is likely to attain an explosive mixture, blasting shall not be done and the workers shall be removed from such working faces or places until such condition has been corrected.

When the methane content of air in face operations exceeds one per cent at any point twelve or more inches from the roof, face, or rib, as determined by a permissible methane detector, a permissible flame safety lamp, or analysis, such condition shall be corrected by improving the ventilation promptly. The electric face equipment at such point shall be turned off and not turned back on until the methane condition is corrected by improving the ventilation.

In gaseous mines, air that has passed through abandoned panel sections shall not be re-used to ventilate live workings. Mines that cannot comply with this requirement at once may continue to operate as at present for a reasonable length of time until future mine development and ventilation can be changed to permit compliance with this section.

No operator of a mine shall refuse or neglect to comply with this section.

Explosion doors shall be provided in a direct line with the mine opening.

Upon the written order of the chief of the division of mineral resources management, all main mine fans installed after September 2, 1941, shall be so arranged that the ventilating current can be quickly reversed. No fan shall be reversed while workers are in the mine unless authority to do so is given, preferably in writing, by the mine foreperson, superintendent, state inspector, or other responsible person. The fan shall be inspected at least daily.

Every main ventilating fan at nongaseous mines shall be kept in operation continuously day and night, unless operations are definitely suspended, except when written permission is given by the inspector to stop it. The permission, or a copy thereof, shall be posted by the mine foreperson in a conspicuous place at the entrances of the mine, and shall state the particular hours the fan may be stopped. The inspector may withdraw or modify such permission at any time and in any manner the inspector deems best. In all cases in which permission has been given by the inspector to stop the ventilating fan, the fan shall be started a sufficient length of time prior to the appointed time for any person 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 employees to leave their working places, for all persons to be out of the mine.

Every main ventilating fan at gaseous mines shall be kept in operation continuously day and night unless operations are definitely suspended. Should it become necessary to stop the fan at any mine, gaseous or nongaseous, because of an accident to part of the machinery connected therewith, or by reason of any other unavoidable cause, the mine foreperson or the foreperson in charge shall, after first having provided for the safety of the persons employed in the mine, order the fans stopped for necessary repairs. Should the ventilating fans be stopped at any time for any reason at any gaseous mine for a period of time sufficient to cause a serious interruption of the ventilation, the source of electric power shall be forthwith disconnected from the mine, and the source of electric power shall not be reconnected with the mine until the fans have been started, and the mine has been examined by the mine foreperson, foreperson, or fire boss, and reported safe. A record of such examination shall be entered in the fire boss record book. The person in charge of the mine at the time of the examination is responsible for the execution of this latter provision.

(B) For the protection of circuits, a switch and circuit breaker shall be installed in the ungrounded side of the circuit but may be omitted from the return side. Fuses may be substituted for circuit breakers transmitting twenty-five kilowatts or less. Each circuit leading in the underground workings of such mine shall be provided with a suitable ammeter. Additional switches shall be installed in the ungrounded side of all branch circuits.

(C) One side of grounded circuits shall be very efficiently insulated from the earth.

(D) All trolley and feed wires shall be placed on the opposite side of the track from refuge holes or necks of room. All lines except telephone, shot firing, and signal lines shall be on the same side as the trolley lines.

(E) All terminal ends of feed and trolley wires shall be guarded to prevent persons from inadvertently coming in contact with them.

(F) 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, except to move a locomotive out of traffic because of a broken trolley pole or fixtures attached thereto. This does not prohibit the operation of a locomotive by means of a cable without the use of the trolley, if the connection with and disconnection from the positive wire is made when the locomotive is not in motion.

(G) Inside the mine the trolley wire shall be installed parallel to the gauge line of the rail and as far away as practical, and in no place closer than six inches from the gauge line, except where written permission is given by the chief. The trolley wire shall be securely supported on hangers efficiently insulated. Such hangers shall be placed at intervals of not exceeding thirty feet and at less intervals if it is necessary to prevent the sag between points of support exceeding three inches. Hangers installed after September 2, 1941, shall be of sufficient height to place the trolley wire within six inches of the roof or cross timbers at the point of trolley wire support, except where the trolley wire may be above the top of the normal seam or draw slate taken with the seam or six feet six inches from the top of the rail.

(H) In underground workings all feed wires shall be in places either above the trolley wire on the same hangers, between trolley wire and rib, or on the rib as close to the roof as practicable, and securely supported on hangers sufficiently insulated, not more than fifty feet apart. If feed wires are installed in entries that are not equipped with trolleys, they are to be installed as close to the rib as practicable.

(I) Recharging stations for battery locomotives located inside a mine shall be adequately ventilated at all times. All charging panels shall be equipped with automatic overload circuit breakers and ammeters. All refuse or movable material of an inflammable nature shall be kept out of such stations.

(J) 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 with such wires, except where such wires are above the top of normal seam or draw slate taken with the seam, or six feet six inches from the top of the rail.

(K) 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 break-through, except in case of systems of mining or equipment approved by the chief.

(L) When necessary to carry bare wires down shafts or slopes used as traveling ways, the wires shall be thoroughly protected so that persons cannot inadvertently come in contact with them.

(M) When positive machine feed wires are extended into rooms, they shall be placed not nearer than four feet from the rail where the room is of sufficient width, and shall only be connected to the positive wire on the entry while in actual use. The wire used for making such connections shall be of sufficient length to reach across the entry, and when the same is disconnected, it shall be removed from the entry or be kept with the machine. No electric wires shall be extended into any room unless a one hundred fifty foot trailing cable will not reach the face of the room, and then not beyond the outside corner of the last break-through, except in the case of systems of mining and equipment approved by the chief. Means shall be provided by which machine runners may readily install the machine cable across the entry so as to render it free from ground, and so the cable will not come in contact with persons or animals required to travel such entry.

(N) Any track or rail that is used as a return circuit shall be properly bonded. When metallic pipelines parallel a rail or track used for return, the pipe may be bonded to the rail at both ends to avoid electrolysis, and if the pipeline is of unusual length, intermediate bonds shall be installed. No pipeline or any part thereof shall be used exclusively as the return. In a section of a mine where electric detonators or electric squibs are used, metallic pipeline rails and return lines in that section shall be bonded together.

(O) All lighting circuits of a mine, whether underground or outside, shall be installed in such a manner that they will not be a fire hazard or will not endanger persons coming in contact therewith.

No operator of a mine shall refuse or neglect to comply with this section.

Effective Date: 06-14-2000

1567.18 Rules for use of alternating current.

When alternating current is used underground in mines, the following rules apply:

(A) On all low voltage circuits all wires shall be protected by a switch and an automatic overload circuit breaker on each wire of the circuit, except that fuses may be substituted for circuit breakers in the case of lighting circuits and in the case of power circuits transmitting twenty-five kilowatts or less. All wires shall be insulated with a standard insulation and shall be placed between trolley wire and rib or on the rib as close to the roof as practicable and securely supported upon hangers efficiently insulated. Additional switches shall be installed in all branch circuits. All points of connection shall be properly protected so that persons cannot inadvertently come in contact therewith. No voltage in excess of two hundred sixty volts measured at the nearest switchboard shall be used in mobile machinery except with the written approval of the chief of the division of mineral resources management.

(B) When high voltage circuits are used, all wires shall be provided with a suitable ammeter and protected by an oil-break switch on each wire of the circuit, such switch to be equipped with an automatic overload trip. All wires shall be insulated with a standard insulation at least fifty per cent higher than the standard for the commercial rated voltage between conductors and ground and installed in conduit or be lead covered with an additional covering of steel armor wire or steel tape, and all wire shall be subject to carrying capacity according to the rules of the national board of fire underwriters. This cable may be installed either in or on the bottom or in the location prescribed for direct current feed lines, except no further insulation shall be required than specified in this section.

(C) No voltage in excess of eight thousand volts between conductor and ground may be used to operate semipermanent and permanent machinery except with the written approval of the chief. All installations shall be made in accordance with the accepted electrical standards and practices, especially with regard to protective switches, insulation materials, clearance danger signs, and gates. The location, ventilation, and protection against fire hazard and personal injury shall be subject to the approval of the chief.

(D) The division of mineral resources management shall accept standard electrical practices in regard to the underground electrical installations and operation of alternating current equipment, but may augment the same to provide additional safeguards. When exercising this authority, the division shall give due consideration to the safety experience in regard to similar installations and the similar operation thereof under similar conditions.

(E) The mine foreperson shall have posted at the mine opening, and in all permanent substations therein, a copy of instructions as to the method of resuscitation of persons suffering from electric shock. All persons working about such stations, or with electric machines, shall familiarize themselves with such rules.

No operator of a mine shall refuse or neglect to comply with this section.
