ARTICLE 15.
COMPRESSED AIR.
(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.
