近距离双突煤层群瓦斯抽采技术分析

Close pairs of Coal Seam Gas Drainage Technical Analysis Group

以中平能化集团天安五矿己15和己16、17煤层为例,采用数值计算等手段对近距离双突煤层群瓦斯抽采技术进行了分析研究,对机巷瓦斯进行了科学的突出预测敏感指标及临界值分析,提出了瓦斯立体抽放技术,取得了较好的实际应用效果。

Significant coal seam gas drainage.The paper by Tianan Zhong Ping Energy Chemical Group Ji15 and Ji16、17 coal seam,for example,by means of numerical calculation of close pairs of Coal Seam Gas Drainage Technology group was analyzed,Gas Lane on the machine a scientific highlight the critical value predicted Sensitive Index and analysis,the three-dimensional gas drainage technology,and achieved good effect in practical application.
