Effective - 28 Aug 1959, 2 histories   293.200. Shaft coal mine outlets and escapement shaft requirements — penalty. — 1. It is unlawful for any owner, agent or operator of any coal mine worked by shaft to employ or permit any person to work therein unless there are to every seam of coal worked in each mine at least two separate outlets, separated by natural strata of not less than three hundred feet in breadth, by which shafts or outlets distinct means of ingress and egress are always available to the persons employed in the mine; but it is not necessary for the two outlets to belong to the same mine if the persons employed therein have safe, ready and available means of ingress and egress by not less than two openings; the communication or roadway between the two openings, or the two openings furnished by a connection between two distinct mines, shall at all times be kept clean and of such width and height as to make the same safe and available for a speedy exit in case of accident.  2. The escapement shaft shall be fitted with safe and available appliances by which the persons employed in the mine may readily escape in case an accident occurs deranging the hoisting machinery at the main outlets, and such means or appliances for escape shall always be kept in a safe condition, and in no case shall an air shaft with a ventilating furnace at the bottom be construed to be an escapement shaft within the meaning of this section. The cage or cages and other means of egress shall at all times be available for the persons employed when there is no second outlet.  3. To all other coal mines, whether slopes or drifts, two such openings or outlets must be provided within twelve months after shipments of coal have commenced from such mine, and in case such outlets are not provided as herein stipulated, it shall not be lawful for the owner, agent or operator of such slope or drift to permit more than five persons to work therein at any one time.  4. Any owner, agent or operator of a coal mine in this state violating the provisions of this section shall be deemed guilty of a misdemeanor, and for each offense, on conviction, shall be fined not less than fifty nor more than two hundred dollars, or by imprisonment in the county jail not less than three nor more than twelve months, or by both such fine and imprisonment. ­­-------- (L. 1959 S.B. 188 §§ 20, 21)

Effective - 28 Aug 1959, 2 histories   293.210. Shaft coal mines, ventilation requirements. — 1. The owner, agent or operator of every coal mine, whether operated by shaft, slope or drift, shall provide and maintain for every such mine a good and sufficient amount of ventilation for such men as may be employed therein, the amount of air in circulation to be in no case less than one hundred cubic feet for each man per minute, measured at the foot of the downcast, and the same to be increased at the discretion of the director of the division according to the character and extent of the workings, or to the amount of powder used in blasting and said volume of air shall be forced and circulated to the face of every working place throughout the mine, so that such mine shall be free from standing powder smoke and gases of every kind.  2. All doors set on main entries for the purpose of conducting the ventilation shall be so constructed and hung as to close of themselves when opened, and shall be made sufficiently tight to effectually obstruct the air currents. In all mines employing fifty or more men a trapper shall be kept in attendance upon such doors to see that they are kept securely closed and the air currents properly controlled.  3. Whenever the director shall find men working without sufficient air, or under any unsafe conditions, he shall first give the operator a reasonable notice to rectify the same, and upon his refusal to do so, may himself order them out until said portions of said mine shall be put in proper condition.  4. The ventilation required by this section may be produced by any suitable appliances, but in case a furnace shall be used for ventilating purposes, it shall be built in such a manner as to prevent the communication of fire to any part of the works, by lining the upcast with incombustible material for a sufficient distance up from said furnace.  5. The currents of air in coal mines shall be so split as to give a separate current to at least every fifty men at work, and the director shall have discretion to order a separate current for a smaller number of men, if special conditions render it necessary. ­­-------- (L. 1959 S.B. 188 §§ 22, 23)

All owners, agents or operators of coal mines shall require of all miners or other persons employed in and about a mine, using gun or blasting powder or other explosives, to have and keep a strongbox in which all surplus gun and blasting powder or other explosives in the mine shall be kept, excepting so much as is necessary for immediate use. These boxes shall be kept locked and not opened unless it be to put in or take out powder. Nor must these strong (or powder) boxes be kept nearer than one hundred feet to the place of blasting.  2. And in all dry and dusty coal mines discharging light carbonated hydrogen gas, or in mines where the coal is blasted off the solid, shot firers must be employed by the operator of said mine or mines, to fire all shots after the employees and other persons have retired from the mine.  3. And all shots prepared by the miner for the extraction of coal from off the solid must be so placed, drilled and charged that the same, when fired, shall perform safely the duty required of such shots; but if the shot firers find or discover that a drill hole is gripping too much, or that it is drilled too much into what the miners term "the tight", and as may in the judgment of the shot firers prove a windy, blown-out or otherwise dangerous shot, said shot firers shall there and then condemn such shot as too dangerous to fire and pass the same without firing it.  4. It shall also be the duty of the shot firers to notify the mine foreman as soon as practicable, when a shot is condemned, who shall in turn attract the attention of the miner or miners responsible for the preparation of said condemned shot, and said miner or miners shall immediately after returning to work provide the necessary remedy to render the said condemned shot harmless.  5. Any agent, owner or operator of any coal mine in this state violating the provisions of this section shall be deemed guilty of a misdemeanor, and for each offense, on conviction, shall be fined not less than one hundred dollars nor more than two hundred and fifty dollars, or by imprisonment in the county jail not less than six months nor more than one year, or by both such fine and imprisonment, proceedings to be instituted in any court having competent jurisdiction. ­­-------- (L. 1959 S.B. 188 §§ 28, 29)
