The roof and ribs of all active underground roadways, travelways, and working
places shall be supported or otherwise controlled adequately to protect
persons from falls of the roof or ribs. A roof control plan and revision thereof
suitable to the roof conditions and mining system of each mine and approved
by the commissioner or his authorized representative shall be adopted and set
out in printed form within six (6) months after June 16, 1972, and shall be kept
on file in the district office of the district where the mine is located. The plan
shall show the type of support and spacing approved by the commissioner. No
person shall proceed beyond the last permanent support unless adequate
temporary support is provided. A copy of the plan shall be furnished the
commissioner or his authorized representative and shall be available to the
miners and their representatives.
The method of mining followed in any mine shall not expose the miner to
unusual dangers from roof falls caused by excessive widths of rooms and
entries or faulty pillar recovery methods.
The licensee, in accordance with the approved plan, shall provide at or near
each working face and at other locations in the mine as the commissioner or
his authorized representative may prescribe an ample supply of suitable
materials of proper size with which to secure the roof of all working places in a
safe manner. Safety posts, jacks, or other approved devices shall be used to
protect the workmen when roof material is being taken down, crossbars are
being installed, roof bolt holes are being drilled, roof bolts are being installed,
and in other circumstances that may be appropriate. Loose roof and
overhanging or loose faces and ribs shall be taken down or supported. Except
in the case of recovery work, supports knocked out shall be replaced promptly.
Roof bolt recovery for reuse shall not be permitted.
Where workmen are exposed to danger from falls of roof, face, and ribs they
shall examine and test the roof, face, and ribs before any other work is
performed or machinery is started, and as frequently thereafter as may be
necessary to insure safety. When dangerous conditions are found, they shall
be corrected immediately.
Within forty-eight (48) hours before the commencement of any retreat mining
or pillaring operations, the mine operator shall notify the Office of Mine Safety
and Licensing of its intention of beginning or resuming retreat mining or
pillaring. The Office of Mine Safety and Licensing shall document such
notification in writing. Upon such notification within the forty-eight (48) hour
period from a mine operator, and, before retreat mining or pillaring operations
can begin, the office shall ensure that every person who will be participating in
the retreat mining operations is trained in the operator's pillar removal plan.
