Map of Mines. Copies Furnished Mine Inspector. Surveys Ordered. When.

SEC. 9. The owner, operator, lessee or person in charge of any coal mine, shall make or cause to be made an accurate map or plan of such mine, drawn to a scale of not more than two hundred feet to the inch, on which shall appear the name of the State, county and township in which the mine is located, the designation of the mine, the name of the company or owner, operator, lessee or person in charge, the certificate of the mining engineer or surveyor as to the accuracy and date of the survey, the north point and the scale to which the drawing is made. Every such map or plan shall correctly show the surface, boundary lines of the coal rights pertaining to each mine, and all sections or quarter section lines or corners within the same; the lines of town lots and streets; the tracks and sidetracks of all railroads, the location of all wagon roads, rivers, streams, ponds. For the underground workings said map shall show all shafts, slopes, tunnels, or other openings to the surface or to the workings of a contiguous mine, all excavations, entries, rooms and crosscuts; the location of the escape ways, and of the fan or other means of ventilation, and the direction of air currents and the location of permanent pumps, hauling engines, engine plans, abandoned work, fire walls and standing water. A separate and similar map drawn to the same scale in all cases, shall be made of each and every seam of coal operated in any mine in this State. A separate map shall also be made of the surface whenever the surface buildings, lines or objects are so numerous as to obscure the details of the mine workings, if drawn upon the same sheet with them, and in such case the surface map shall be drawn upon transparent cloth or paper, so that it can be laid upon the map of the underground workings and thus truly indicate the local relations. of lines and objects on the surface to the excavations of the mine, together with any other principal workings of the mine. The original or true copies of all such maps shall be kept at the office of the mine, and true copies thereof shall also be furnished the State inspector of coal mines within thirty days after the completion of the same. The maps so delivered to the inspector shall be the property of the State, and shall remain in the custody of the Commissioner of Labor during his term of office, and be delivered to his successor in office. They shall be kept at the office of the Commissioner of Labor, and be open to examination of all persons interested in the same, but such examination shall be made only in the presence of the inspector, Commissioner of Labor, or his office assistant; no copies of the same to be made without the written consent of the operator or owner of the property, except as herein otherwise provided. An accurate extension of the

last preceding survey of every mine in active operation shall be made in every twelve months prior to July first of every year, and the result of such survey, with the date thereof, shall be promptly and accurately entered upon the original map; and a true, correct and accurate copy of said extended map shall be forwarded to the inspector of coal mines so as to show all changes in plan of new work in the mine, and all extensions of old workings to the most advanced face or boundary of said workings which have been made since the last preceding survey; and the parts of the mine abandoned or worked out after the last preceding survey shall be clearly indicated and shown by colorings, which copy must be delivered to such inspector of coal mines within thirty days after the last survey is made. When any coal mine is worked out or is about to be abandoned, or indefinitely closed, the owner, operator, lessee or person in charge of the same shall make or cause to be made a complete and extended map of said mine, and the result of the same shall be duly extended on all maps of the mine and copies thereof so as to show all excavations and the most advanced workings of the mine and their exact relations to the boundary or section lines on the surface, and deliver to the inspector a copy of the completed map. The State coal mine inspector shall order a survey to be made of the workings of any mine and the result to be extended on the maps of the same, and the copies thereof, whenever in his judg ment the safety of the working men, or the safety of an adjoining mine requires it; and if not made by the owner, operator, lessee or person in charge when ordered by the inspector, it shall be made or caused to be made by the inspector and paid for by the State, and the amount collected from the owner, operator, lessee or person in charge, as other debts are collected.

Abandoned Mines.

Ventilation.

SEC. 11. For the purpose of ventilation the mines shall be furnished with not less than one hundred cubic feet of air per minute for each person employed in the mine, or three hundred cubic feet of air per minute for each machine, mule or other draught animal in the mine, the measurements to be made at any point of the intake airways. The amount

of air shall be so distributed as to give all employes air of reasonable purity to keep the working places in a healthy condition, free from noxious gases and deleterious air, and no more than one hundred men to work on any split of air. In mines generating explosive gas of a sufficient quantity to be detected by an ordinary safety lamp, the quantity shall not be less than two hundred cubic feet of air per minute for each person and six hundred cubic feet for each machine, mule or other draught animal, and the mine shall be operated with locked safety lamps and examined by a competent person each morning before the men enter their working places.
