The following rules shall govern in the rock-dusting of mines:
(1)All mines, or parts of mines, or sections thereof, shall be rock-dusted if conditions
are found to be dusty or hazardous, after proper inspection. In the event such
conditions are found to exist, then the commissioner or his authorized
representative shall require the necessary rock-dusting to make the mine, part of the
mine, or section safe.
(2)In all mines, accumulations of excessive loose coal and fine dry coal dust shall be
removed from the mine, and all operating sections kept thoroughly rock-dusted, and
the dust on the mine floor allayed by methods approved by the commissioner, but in
every mine, or in any part or section thereof, rock-dusting shall be applied to
maintain at all times a minimum percentage of sixty-five percent (65%) of
noncombustible matter to within forty
(40)feet of the faces, including last open
crosscuts, and under certain special conditions the department may require that
places be rock-dusted to the faces, and that additional rock-dust be added.
