摘要
为制定可行的瓦斯抽采方案,在确定顶板裂隙基本情况下,应用SF6示踪技术研究了平顶山煤矿十矿己-24130岩石工作面采空区三维空间漏风路径及瓦斯运移路径。结果表明:在采样高度49 m的裂隙带上部,距离工作面距离越远,示踪气体浓度越低,上邻近层瓦斯释放量越大。该研究结果为确定瓦斯抽采钻孔位置提供参考。
In order to establish a feasible scheme of gas extraction, the SF6 tracer technique was used to study the three-dimensional air leakage path and gas migration path in the goaf of Ⅵ-24130 which in the ten mine of Pingdingshan coal under the condition of the roof fissure. The results show that the longer the distance from the working face is, the lower the concentration of tracer gas is, so the amount of gas released from upper adjacent layer is higher, which at the upper part of the fractured zone with a height of 49 m. The results provide a reference for the location of gas drainage boreholes.
