摘要
根据上湾煤矿煤层较硬、顶底板条件好易于支护、井下三条大巷布置间距短的特点,兼顾永久避难硐室地面钻孔位置选择,就近布置在工业场地内的方针,同时就避难硐室断面形状可采用半圆拱和矩形两种形式进行方案比选剖析,对井下永久避难硐室的位置、支护等进行设计。
According to the features of hard seam, easy support of the roof and floor, and a short distance between the mine three roadways in Shangwan Mine, in consideration of the selection of surface borehole drilling location for the permanent refuge chamber in the underground mine and the drilling location closely set within the surface industrial park, with the plan comparison and selection analysis on the half arch or the rectangle cross section of the refuge chamber, the design was conducted on the location, support and other of the permanent refuge chamber in the underground mine.
