| 摘 要： | 为了提高抽采瓦斯钻孔的抽采效果,根据发耳矿井的现场测试,通过观察距穿层抽采钻孔不同距离的压力观测钻孔的瓦斯压力,利用瓦斯压力指标、瓦斯抽采率指标和灰色关联分析法相结合的方法进行分析,最终确定了7#煤层的瓦斯抽采有效半径,为突出工作面采掘工作前的预抽提供一定理论依据。

| Abstract: | In order to improve gas drainage effect of drainage holes,according to site testing in Faer Coal Mine,by observing the gas pressure of the gas pressure hole at different distances from the crossing holes,the gas pressure index and gas drainage efficiency are analyzed by gray correlation analysis method,effective gas drainage radius of 7# coal seam are ultimately determined.The result provides certain theoretical basis for gas drainage at the outburst working face before mining. |
