Section 480-3-3-.04 - Structures Over Or Near Mine Openings

(1)Nonflammable Housing Over Mine Openings - Only housing having a framework of metal or wood, and metal or other nonflammable sides and roof and dirt, gravel, concrete or other fireproof flooring, shall be erected over any shaft, tunnel, portal or other mine opening. All non-fireproofed structures constructed after the effective date of these rules and located within 50 feet of such shaft, tunnel, portal or other mine opening shall be made fireproof or removed.

(2)Nonflammable Material and Buildings Near Mine Openings - Timber framing or storage sheds or any flammable structures or piles of flammable material other than the current supply of mine timbers and ties shall not be placed or permitted to remain within one hundred (100) feet of any mine opening, shaft house, hoisting engine house or ventilating fan house; provided, however, that wooden head-frames and wooden structures within one hundred (100) feet of shaft house over or near shafts or openings, which have been returned airways continuously for the past two years, need not be removed during the time said shafts or openings continue to be return airways at all seasons, and said shafts or openings are guarded by fireproof doors and other fire prevention equipment satisfactory to the Department.

(a) When the portal of any mine opening or the collar of any shaft is covered by a flammable building built prior to the date these rules become effective, such building shall be permitted to remain. In such case, a fireproof door shall be provided for such mine opening which shall be and shall fit as nearly gas tight as possible. Said door shall be installed in such a way that the opening can be closed from the outside of the building by a pull wire or rope, in the event of fire. This door shall close automatically upon release of the wire or rope. If a wire or metal rope is used, there shall be several fusible links in it or other efficient means shall be provided to cause the door to close in case of an outside fire. If a fiber rope is used, it shall be of the minimum necessary size and be readily destroyed by fire.
