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 in high pumping tunnel with outburst, study on gas drainage technology of high suction roadway in Dongqu Coal Mine of Xishan Coal and Electricity Group was carried out. By analyzing the law of movement and deformation of overburden strata and the development and distribution of fracture field and the relationship between the effect of gas drainage and gas drainage, the similar laboratory simulation and industrial experimental research methods were used to determine the reasonable location parameters of high pumping tunnel, In combination with other drainage facilities such as low-pumping roadways, a three-dimensional and highly efficient drainage system has been formed in the whole process and the mined-out area to create the best extraction environment.
