摘要
赛尔能源公司五矿A2004工作面为近距离煤层群开采的工作面,回采期间发生瓦斯超限,根据现场实际,采用高位钻孔抽采工作面上覆采空区瓦斯的解决方案,并合理确定抽采相关参数,解决工作面瓦斯超限问题。
A2004 working face in No.5 Mine of Xinjiang Saier Energy Company belongs to mining face of close range coal seam group,the gas overrun occurred during mining,according to the actual operation of the drilling,the gas in the upper corner of goaf is drained by using the high-level boreholes,the relevant parameters was also determined reasonably.The application of these method has solved the problem of gas overrun working face.
