(225 ILCS 705/15.01) (from Ch. 96 1/2, par. 1501) Sec. 15.01. Compressed air shall be conducted from surface compressors, except as provided in Section 15.11, to within a practical working distance of the face by air lines. Said air lines when new and first installed, shall be tested to withstand an approximate minimum pressure of 20,000 pounds per square inch. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.02) (from Ch. 96 1/2, par. 1502) Sec. 15.02. Air lines shall be grounded at the compressor and, if practicable, at other low-resistance ground connections. Air lines shall not be connected to tracks, water lines, or other electric-power return conductors. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.03) (from Ch. 96 1/2, par. 1503) Sec. 15.03. After the effective date of this Act, unions shall be installed in steel air lines at not more than 1,000 foot intervals, and at the inby end of the air lines. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.04) (from Ch. 96 1/2, par. 1504) Sec. 15.04. Shut-off valves shall be installed, after the effective date of this Act, every 1,000 feet in all air lines and, in all branch air lines at a point near the main air lines. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.05) (from Ch. 96 1/2, par. 1505) Sec. 15.05. Air lines shall not be repaired when air pressure is in the line. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.06) (from Ch. 96 1/2, par. 1506) Sec. 15.06. Blow-down valves or filling valves shall be located around a corner of the coal pillar except where portable compressor machines are used for breaking down coal. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.07) (from Ch. 96 1/2, par. 1507) Sec. 15.07. When blow-down valves are opened to discharge the compressed air tube, they shall remain open until time to place the tube in the next borehole. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.08) (from Ch. 96 1/2, par. 1508) Sec. 15.08. When a compressed air tube fails to discharge, the air line leading to the tube shall be disconnected at the blow-down valve and the tube shall be dragged by means of the air line to a safe place. The tube shall be marketed with warning signs and repair work shall not be done on a tube or shell until the pressure is reduced to zero. Except, however, this provision shall not apply to shells or tubes charged from a shooting valve that can be reversed and the air let out to reduce the pressure in the shell or tube to zero. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.09) (from Ch. 96 1/2, par. 1509) Sec. 15.09. All persons shall be removed from adjoining working places where there is a danger of breaking through, and they shall be at a safe distance around a corner while coal breaking is in progress. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.10) (from Ch. 96 1/2, par. 1510) Sec. 15.10. Compressed air may be used on shift and while men are in the mine, for breaking down coal or other materials. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.11) (from Ch. 96 1/2, par. 1511) Sec. 15.11. Air compressors, whether fixed or portable, for compressing air to be used in breaking down coal or other materials, may be located underground if the compressor has adequate cooling devices which prevent the creation of excessive temperatures in the machine and, in gassy mines, if the compressor is equipped with permissible motors and other appurtenances. (Source: Laws 1953, p. 701.)

(225 ILCS 705/15.12) (from Ch. 96 1/2, par. 1512) Sec. 15.12. In non-gassy mines, permissible motors and other appurtenances shall not be required on air compressors located underground. (Source: Laws 1953, p. 701.)
