Study on protection layer exploiting technology and press released area of wugou coal mine
Abstract：It was testified based on theory research and spot application that exploiting protection layer and pre - draining gas were the best effectively and economically measures for region coal and gas outburst control. For the mines that are applying this technology, the first step is obtaining press released area, then gas drainage system and working faces can be designed. According as distortion mechanism of wall rock and occurrence characteristic of gas, with a view to practice application of protection layer exploiting in Wugou coal mine Anhui wanbei coal and electricity group, reasonable coal seam mining sequence is analyzed and press released area is calculated out in this paper. The research result will provide some reference basis for gas control in spot.
