摘　　要：走向高位裂隙钻孔是矿井上隅角瓦斯治理的一种有效方法。在分析走向高位裂隙钻孔抽采机理的基础上,以陈四楼煤矿21016工作面为例进行了走向高位裂隙钻孔抽采试验,对比分析并确定了试验区域终孔距顶板高度、距巷帮深度、钻场间距等最佳参数。试验表明,走向高位裂隙钻孔抽采能够高效治理回采工作面上隅角瓦斯,实现快速回采。An effective method for highly-located fractured borehole gas control in the upper corner of the mine. Based on the analysis of the mechanism of highly-located fractured borehole drainage, the21016 working face of Chensilou coal mine was taken as an example to carry out the highly-located fracture drilling and extraction test. The optimal parameters such as the height of the final hole from the top of the test area, the depth of the roadway and the spacing of the drill field were determined and compared. The test shows that the highly-located fractured borehole extraction can effectively control the gas at the corner of the working face and achieve rapid recovery.
