§ 45-501. Maps of mines.

The owner, agent, lessee or operator of every coal or other mine, shall make, or cause to be made by a competent mining engineer or surveyor, an accurate map or plan, of such mine, no smaller than on a scale of two hundred (200) feet to an inch, which map shall show as follows:

(a) All measurements of said mines in feet or decimal parts thereof.

(b) All openings, excavations, shafts, tunnels, slopes, planes, main entries, rooms, and other parts, in proper numerical order in each opening or stratum of coal in said mine.

(c) The directions of the air currents, when practicable, by darts, or arrows, marked thereon.

(d) An accurate delineation of the boundary lines between said mine and all adjoining mines or coal lands where owned or operated by the same operator or other operators, and the relation and proximity of the workings of said mine to any other adjoining mine or coal land.

(e) The bearings and lengths of each tunnel, or entry, or the boundary of property lines.

The said map or plans, or a true copy thereof, shall be kept in the general mine office by the said operator or superintendent for the use only of the mine officials and mine inspectors, and for the inspection of all persons working in said mines whenever said person or persons shall have cause to fear that any working place is becoming dangerous by reason of its proximity to other workings that may contain water or dangerous gas.
