摘要
东曲矿是高瓦斯矿井,单纯的通风方法已经难以将瓦斯含量控制在安全范围内,为有效预防煤矿瓦斯突出的危险,必须采取措施进行瓦斯抽采,而打钻抽采和钻孔封孔效果,直接关系到能否安全高效抽采,针对这一问题,本文提出了一系列的安全技术措施。
Dongqu Coal Mine is a high gassy mine, so it is very difficult to control the gas content within the scope of the security merely by simple ventilation method.In order to effectively prevent coal mine from gas outburst, measures must be taken to conduct gas extraction. Then the result of drilling extraction and drilling hole sealing it is directly related to the safety and efficiency of extraction. In order to solve this problem, this paper puts forward a series of safety technical measures.
