东曲矿高抽巷合理位置研究

Study on Reasonable Position of High Extracted Roadway in Dongqu Coal Mine

综采工作面高抽巷在实际应用过程中,若不充分考虑开采引起的覆岩活动规律,实际抽 放瓦斯效果会不理想.本文通过相似材料模拟试验,对西山煤电集团东曲矿28202工作面高抽巷位 置进行合理布置,并通过现场工业试验,对高抽巷的位置进行优化,得出接替工作面高抽巷布置时应 考虑进一步增大内错距离,内错工作面30 -50 m,高抽巷主要部分的高度增至50 -60 m. 最终确保 了瓦斯的有效抽采.

In the process of practical application of fully mechanized coal mining face, if the law of overburden movement in roof caused by mining were not fully considered, the actual effect of gas drainage would be not ideal. In this paper, by the similar material simulation testing, the position of the high pumping roadway in the Dongqu coal mine of Xishan Coal and Electricity Group is arraned reasonably, and the position of the high pumping roadway is op-timized by the field industrial experiment, and the high pumping roadway Should be considered to further increase the interval distance to 30 -50 m, high pumping height to 50 -60 m in major part. So to achieve the purpose of effective gas drainage.
