25 Pa. Code § 88.136 - Blasting: near underground mines
(a)
When a surface mine is operating within 500 feet of an active deep mine, the
surface mine operators shall notify the surface mine inspector in advance of
his intention to blast. The surface mine inspector shall, in turn, notify the
deep mine inspector and together they shall instruct both the surface mine
operator and the deep mine operator as to procedure.
(b) Prior to blasting, the surface mine
operator shall give sufficient advance notice to the deep mine operator,
superintendent or mine foreman of his intention to blast.
(c) The deep mine operator, superintendent or
mine foreman shall remove all workmen from the mine. The surface mine operator
shall ascertain that all workmen have been removed from the mine before
preparations for blasting may begin.
(d) When there is a known or suspected
connection between the deep mine and the surface mine, the operator,
superintendent or mine foreman of the deep mine shall, after the blast, make or
cause to be made sufficient tests to insure the absence of carbon monoxide or
other harmful gases before allowing workmen to reenter the mine.
(e) The deep mine operator, superintendent or
mine foreman shall make or cause to be made sufficient examinations of the deep
mine to determine whether any other danger exists before allowing workmen to
reenter the mine, just as other preshift examinations are
made.
