浅析采掘工作面瓦斯抽放系统设计

The Design of Gas Drainage System in Working Face

为减少矿井和采区瓦斯涌出量杜绝瓦斯事故,对阳煤集团景福煤矿15号煤层进行了瓦斯浓度测定、预抽煤层的瓦斯钻孔量、煤层抽采工艺等进行了严格的设计,把所有煤层瓦斯压力降至0.74 MPa,达到了瓦斯抽采效果,满足了瓦斯抽放系统的设计要求。

In order to reduce the mine gas emission and mining area to eliminate the gas accident,Jingfu Yangmei group on the 15 th coal seam of coal mine gas concentration measurement,the drainage of coal seam in the amount of gas drilling,coal extraction technology and so on has carried on the strict design,put all the coal seam gas pressure 0.74 MPa,achieved the effect of the gas extraction,satisfying the requirements of the design of gas drainage system.
