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 regional office of the
region 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 Division of Mine Safety of
its intention of beginning or resuming retreat mining or pillaring. The Division of
Mine Safety shall document such notification in writing. Upon notification within
the forty-eight (48) hour period from a mine operator, and, before retreat mining or
pillaring operations can begin, the Division of Mine Safety shall ensure that every
person who will be participating in the retreat mining operations is trained in the
operator's pillar removal plan.
