摘要
对一些高瓦斯矿井来说,其选煤厂煤仓的瓦斯浓度远远超过《煤矿安全规程》规定的安全标准。在筒、槽仓地面的四周开设通风孔进行自然通风;在筒、槽仓上方安装排风管道通入仓内,通过抽出式局部通风机对仓内瓦斯进行强制排放,可达到排放有害气体的目的。
For some high-gas coal mine, gas concentration of coal bunker in coal preparation plant was far more than the required safety standards of the ＂Coal Mine Safety Regulations＂ . As it is mentioned in this paper, opening ventilation holes in the ground around the tube, slot positions for natural ventilation, installing the exhaust pipe through warehousing at the top of the tube slot positions, and mandatorying emissions of gas by Drawer-type local fan can uhimately achieve the purpose of emissions of harmful gases.
