保德煤矿刘家堰高负压瓦斯抽放系统的成功应用

High Gas Drainaging System Success in Baode Coal Mine

神华神东煤炭集团公司保德煤矿(简称保德煤矿)位于山西省保德县,随着瓦斯涌出量的逐年增加,原有刘家堰瓦斯抽放泵站不能满足矿井通风要求,通过对煤层瓦斯基础参数和瓦斯涌出量的分析预测,结合保德煤矿的实际情况,找到了适合保德煤矿开采层瓦斯预抽方法,布置瓦斯抽放管路和地面高负压抽放泵站,从而建立起了一套瓦斯抽放系统,通过该套抽放系统的平稳运行,取得了瓦斯治理的良好效果。

Baode coal mine（Shenhua Shendong Coal Group） located in Baode county of Shanxi Province. With the increase of gas emission the original gas drainage pumping station can not meet the requirement of the mine ventilation, Baode coal mine established a set of gas drainage system,by analysising of the coal seam gas basic parameters and gas emission quantity and Combining with actual situation,Layouting of gas drainage pipe line and high negative pressure pumping station, so that establishing a set of systematic about gas out system. Good results have been achieved by the of gas drainage system.
