摘要
为满足榆树岭煤矿综放工作面瓦斯防治需求,通过对大气压力监测,并根据工作面实际情况采用高位钻孔交替抽放采空区顶部瓦斯,使瓦斯抽采纯量在290.5~1562.3 m^(3)/min之间,单孔瓦斯抽采流量在0.29~0.94m^(3)/min之间,有效控制了综放工作面的瓦斯异常涌出问题。
In order to meet the needs of gas prevention and control in fully mechanized top coal caving face in Yushuling Coal Mine, by monitoring atmospheric pressure and using high boreholes to drain gas alternately from the top of goaf area according to the actual situation of the working face, the pure amount of gas drainage is between 290.5-1 562.3 m^(3)/min, and the gas drainage flow rate of single hole is between 0.29-0.94 m^(3)/min, which effectively controls the problem of abnormal gas emission in fully mechanized top coal caving face.
