摘要
为了提高突出矿井高抽巷瓦斯抽采效率,开展了西山煤电集团东曲煤矿高抽巷瓦斯抽采技术研究。通过分析工作面开采引起上覆岩层移动变形和裂隙场发育分布规律,及其对抽采瓦斯效果的关系,采用实验室相似模拟试验和工业性试验研究方法,确定了高抽巷合理位置参数,结合低抽巷等其他抽采设施,在开采中与采空区形成了全域全过程立体化的高效抽采系统,创造最佳的抽采环境。
In order to improve the efficiency of gas drainage by high pumping lane, open up research by high pumping lane gas drainage in Dongqu mine. After theoretical analysis of the overburden movement and deformation and fracture development field distribution caused by the mining face ,and its relationship to the effects of gas extraction,and similar material simulation and in-situ experiments. Found the appropriate layout position, formed a global three-dimensional whole process efficient drainage system combined with other drainage facilities in the mining and mined-out area and created the best drainage conditions.
