摘要
针对新集一矿13-1煤层的瓦斯灾害情况,结合"先抽后采"和区域性瓦斯抽采的瓦斯治理原则,采用保护层开采卸压瓦斯强化抽采的方法抽采13-1煤层瓦斯,消除了煤层的突出危险性,抽采率达到60%以上,最终实现了煤与瓦斯突出煤层安全快速掘进和高效回采。
In view of the gas disaster situations of the 13 - 1 coal bed in Xinji No. 1 Coal Mine, it drainages the pressure releasing gas in the 13 - 1 coal bed with the protective layer according to the gas governing principle - -＂drainage first, excavation next＂ and the regional gas drainage. The outburst risk of the coal bed is eliminated, and the drainage rate is above 60%. The safe high -speed driving and the highly effective mining in the coal and gas outburst coal bed is realized finally.
