摘要
石港矿15101综放面主采15#煤,鉴于该层煤煤质松软以及顶煤距内错尾巷底板间距较小,容易发生顶煤冒落,不能充分发挥其治理瓦斯的作用。根据内错尾巷实际情况,尝试性地布置在14#煤层。通过对工作面各巷道瓦斯涌出情况现场实测数据的对比分析,以及对内错尾巷布置在14#与15#煤层时,数值模拟结果对比,总结出15101工作面内错尾巷布置在不同高度下的特点及其瓦斯治理效果。
Major mining 15# coal at 15101 fully mechanized caving face of Shigang Coal Mine, in view of this layer of coal is soft and the distance between the top of 15^# coal to the mount is short.It is easily lead the top slap to cave in and can not give full play to gas treating effect. According to realities of inner interlockd tail road tentatively arranged in the 14^# coal bed. Through the comparative analysi of the measured data of each roadway of caving face and the numerical simulation results comparison of inner interlocked tail road arranged in each 14^# and 15^# coal bed, summed up layout features of inner interlocked tail road and gas treating effect at 150101 face.
