摘要
端氏矿北翼进风巷在施工过程中要经过3#煤层,该煤层瓦斯含量高且瓦斯压力大,具有突出危险性。为保证巷道的安全施工,需要对3#煤层采取抽排和防突措施。设计出瓦斯抽采抽排钻孔布置方式,阐述了防突和检验措施,保证了矿井的安全生产。
The north return air roadway is constructed to cut through the No.3 coal seams in Duanshi coal mine, and the coal seam has outburst danger with high gas content and pressure.In order to ensure the safe construction of tunnel,it is so necessary to drain the gas in No.3 coal seam and deal with outbrust. The drill hole layout of gas drainage is designed to drain the gas,and the measures of avoiding outbrust and checkout are discussed, and ensure the safety production of mine.
