煤层群综采工作面瓦斯综合治理方案与评价

Comprehensive Gas Control Scheme and Assessment in Fully Mechanized Face of Coal Seam Group

通过对乌海能源公司五虎山煤矿高瓦斯矿井010907综采工作面瓦斯来源进行分析和理论计算,提出具有针对性的瓦斯抽采方案,结合工作面配有专用排瓦斯巷的瓦斯综合治理措施,达到了消除工作面上隅角、回风巷瓦斯超限的目的,实现了工作面安全、高产高效。

Through the analysis and theoretical calculation of the gas sources in No. 010907 fully-mechanized coal face in Wuhushan Coal Mine of Shenhua Wuhai Coal Group Co. , Ltd. , a targeted gas extraction scheme was proposed, and combining with the comprehensive gas control measures such as driving a special gas drainage gate in the working face, the purpose of eliminating the gas overrun at the upper corner angle of the face and in the return airway was achieved, and the safety, high output and high efficiency of the face were thus realized.
