SUBCHAPTER III--INTERIM MANDATORY SAFETY STANDARDS FOR UNDERGROUND COAL
MINES
Sec. 874. Hoisting and mantrips
(a) Transporting of persons; required equipment and capabilities; safety
catches; daily examinations; operators
Every hoist used to transport persons at a coal mine shall be
equipped with overspeed, overwind, and automatic stop controls. Every
hoist handling platforms, cages, or other devices used to transport
persons shall be equipped with brakes capable of stopping the fully
loaded platform, cage, or other device; with hoisting cable adequately
strong to sustain the fully loaded platform, cage, or other device; and
have a proper margin of safety. Cages, platforms, or other devices which
are used to transport persons in shafts and slopes shall be equipped
with safety catches or other no less effective devices approved by the
Secretary that act quickly and effectively in an emergency, and such
catches shall be tested at least once every two months. Hoisting
equipment, including automatic elevators, that is used to transport
persons shall be examined daily. Where persons are transported into, or
out of, a coal mine by hoists, a qualified hoisting engineer shall be on
duty while any person is underground, except that no such engineer shall
be required for automatically operated cages, platforms, or elevators.
(b) Promulgation of other safeguards
Other safeguards adequate, in the judgment of an authorized
representative of the Secretary, to minimize hazards with respect to
transportation of men and materials shall be provided.
(c) Rated capacities; indicator for position of cage
Hoists shall have rated capacities consistent with the loads handled
and the recommended safety factors of the ropes used. An accurate and
reliable indicator of the position of the cage, platform, skip, bucket,
or cars shall be provided.
(d) Methods for signaling between shaft stations and hoist rooms
There shall be at least two effective methods approved by the
Secretary of signaling between each of the shaft stations and the hoist
room, one of which shall be a telephone or speaking tube.
(e) Braking equipment for haulage cars used in underground mines
Each locomotive and haulage car used in an underground coal mine
shall be equipped with automatic brakes, where space permits. Where
space does not permit automatic brakes, locomotives and haulage cars
shall be subject to speed reduction gear, or other similar devices
approved by the Secretary which are designed to stop the locomotives and
haulage cars with the proper margin of safety.
(f) Automatic couplers for haulage equipment
All haulage equipment acquired by an operator of a coal mine on or
after one year after the operative date of this subchapter shall be
equipped with automatic couplers which couple by impact and uncouple
without the necessity of persons going between the ends of such
equipment. All haulage equipment without automatic couplers in use in a
mine on the operative date of this subchapter shall also be so equipped
within four years after the operative date of this subchapter.
