SECTION 1. Be it enacted by the People of the State of Illinois, represented in the General Assembly: That an Act entitled, "An Act to revise the law in relation to coal mines and subjects relating thereto and providing for the health and safety of persons employed therein." approved June 6, 1911, in force July 1, 1911, as subsequently amended, be and the same is hereby amended, by amending section fourteen (14) thereof to read as follows:

$ 14. VENTILATION.] (a) At every coal mine there shall be provided, supplied and maintained an amount of air which shall not be less than one hundred (100) cubic feet per minute for each person, and not less than five hundred (500) cubic feet per minute for each animal in the mine, measured at the foot of the downcast and of the upcast; except that in gaseous mine there shall be not less than one hundred and fifty (150) cubic feet of air per minute for each person in the mine. The inspector shall have power by order in writing to require these quantities to be increased.

(b) The main current of air shall be so split or subdivided as to give a separate current or reasonably pure air to every 100 men at work, and the inspector shall have authority to order, in writing, separate currents for smaller groups of men, if, in his judgment, special conditions render it necessary.

(c) Doors, curtains or brattices shall be placed at such places as may be designated by the mine manager, subject to the approval of the State Inspector, to conduct into the working places an amount of air sufficient to render the working places reasonably free from deleterious air of every kind.

(d) Away from the pillar for the mine bottom, cross-cuts between entries shall be made not more than sixty feet apart without permission of the State Inspector of the district and then only in case of "faults." When such consent is given, brattice or other means must be provided within sixty feet of the face to convey the air to the working place until a cross-cut is opened up.

When undercut or sheared, the entry, cross-cut and room neck may be advanced concurrently, but not more than one cutting shall be shot in the room-neck until the cross-cut is finished; and after the entry has advanced fifteen feet beyond the location of the new cross-cut, only one shot shall be fired in the entry to two in either or both the cross-cut and room-neck at the same shooting time.

Whe

vanced c open cro

location

not undercut or sheared, the entry and cross-cut may be adoncurrently, but no room shall be opened in advance of the last s-cut, and after the entry has advanced fifteen feet beyond the

of

a new cross-cut only one shot shall be fired in the entry to two in t he cross-cut at the same shooting time.

Not more than three shots shall be exploded at one shooting time ahead of the last open cross-cut.

(e) After the taking effect of this Act, the first cross-cut between all rooms off any entry shall not be more than sixty (60) feet from the rib of the entry. Additional cross-cuts shall not be more than sixty (60) feet apart: Provided, however that if in any mine the conditions are such that in the judgment of the duly accredited representative of the Department of Mines and Minerals, expressed in writing, it is considered equally safe and more advantageous to leave a blind pillar between not less than every three rooms, the Department of Mines and Minerals shall have power to grant the authority to leave said pillar subject to review by the Department of Mines and Minerals on formal complaint of the representative of either party in interest and after an open hearing.

(f) All cross-cuts connecting inlet and outlet air courses, except the last one nearest the face, shall be closed with substantial stoppings to be made as nearly air-tight as possible. In the making of the airtight partitions or stoppings, no loose material or refuse shall be used.

Cross-cuts between rooms except the one nearest the face, shall be closed sufficiently to carry to the working places the amount of air required by law.

(g) All possible care and diligence shall be exercised in the examination of working places, especially for the investigation and detection of explosive gases therein, and where found, such gas shall be removed by a special current of air produced by bratticing or from a pipe, before men are permitted to work in such places with other lights than safety lamps.

(h) If, in any mine, the conditions are such that in the judgment of the mine manager or the judgment of the State Mine Inspector expressed in writing, it is necessary to use safety lamps only in working said mine, other lights shall not be used therein.

(i) The air from the outlet of the stable shall not pass into the intake air current used for ventilating the working parts of the mine.

(j) All doors in mines, used in guiding and directing the ventilating currents shall be hung and adjusted so as to close automatically.

(k) At all doors through which three or more drivers are hauling coal on any one shift, an attendant shall be employed on said shaft [shift] for the purpose of opening and closing said doors when trips of cars are passing to and from the workings: Provided, the mine inspector in case of specially dangerous conditions, shall have power to require in writing that an attendant be placed at doors through which less than three drivers shall pass. Places for shelter shall be provided at such doorways to protect the attendants from being injured by the cars while attending to their duties: Provided, that in any or all mines, where

doors are constructed in such a manner as to open and close automatically, attendants and places for shelter shall not be required.

(1) If the inspector shall find men working without the amount of air required by law, he shall at once notify the mine manager to increase the amount of air in accordance with the law. Upon the failure or refusal of the manager to act promptly, and in all cases where men are endangered by such lack of air, the inspector shall at once order the men affected out of the mine.

(m) In case the passageways, roadways or entries of any mine are so dry that the air becomes charged with dust, the operator of such mine must have such roadways regularly and thoroughly sprayed, sprinkled or cleaned.

(n) At all mines employing over one hundred (100) men underground and in all mines generating fire damp, the ventilating fan shall be run both day and night; at all mines employing less than one hundred (100) men underground, the fan shall be run at its usual speed for six (6) hours before men go into the mine to work. A recording pressure gauge shall be maintained in connection with each fan at all times: Provided, nothing in this clause shall apply to mines employing ten men or less.
