Title 30 - Mineral Resources
(a) Except as provided in §§75.385 and 75.386, at least two separate and distinct travelable passageways shall be designated as escapeways and shall meet the requirements of this section. (b) Escapeways shall be provided from each working section continuous to the surface. (c) Each escapeway shall be— (1) Maintained in a safe condition to always assure passage of anyone, including disabled persons; (2) Clearly marked to show the route of travel to the surface; (3) Provided with ladders, stairways, ramps, or similar facilities where the escapeways cross over obstructions; and (4) Maintained at least 4 feet wide by 5 feet high. If the pitch or thickness of the coal seam does not permit these dimensions to be maintained other dimensions may be approved in the ventilation plan. (5) Provided with a continuous directional lifeline or equivalent device that shall be— (i) Installed and maintained throughout the entire length of each escapeway as defined in paragraph (b) of this section; (ii) Made of durable material; (iii) Marked with a reflective material every 25 feet; (iv) Located in such a manner for miners to use effectively to escape; (v) Equipped with directional indicators, signifying the route of escape, placed at intervals not exceeding 100 feet; and (vi) Securely attached to and marked to show the location of any SCSR storage locations in the escapeways. (d) Surface openings shall be adequately protected to prevent surface fires, fumes, smoke, and flood water from entering the mine. (e) Primary escapeway. One escapeway that shall be ventilated with intake air shall be designated as the primary escapeway. (f) Alternate escapeway. One escapeway that shall be designated as the alternate escapeway shall be separated from the primary escapeway for its entire length. (g) Mechanical escape facilities shall be provided— (1) For each shaft or slope opening that is part of a primary escapeway; and (2) For slopes that are part of escapeways, unless ladders are installed. (h) Within 30 minutes after mine personnel on the surface have been notified of an emergency requiring evacuation, mechanical escape facilities shall be operational at the bottom of each shaft and slope opening that is part of an escapeway. (i) Except where automatically activated hoisting equipment is used, the bottom of each shaft or slope opening that is part of a primary escapeway shall be equipped with a means of signaling a surface location where a person is always on duty when anyone is underground. When the signal is activated or the evacuation of personnel is necessary, the person on duty shall assure that mechanical escape facilities are operational as required by paragraph (h) of this section.
