Abstract
The problem of rib spalling of working face is a key problem for the realization of up-dip mining face with large mining height, according to the 3210 working face of 3# coal seam in Holzer Singh of coal mine, made the mechanics analysis of rib spalling in the up-dip mining face with large mining height, analyzed the stability analysis the coal wall of working face by the experimental methods,and put forward the pressure control technology scheme of the up-dip mining face with large mining height.关键词
