摘要
92105 掘进工作面上方采空区内存在大量积水.为了保证 92105 掘进工作面的安全施工,在 92013 胶带巷内施工远距离探水钻孔,并对 91105 采空区内的积水进行排放.在探放水时,共施工了 7 个钻孔.试验结果表明,在采用超前探水钻孔后,可以保证92105 掘进工作面进尺552 m,节约工期 46 d,节省成本4.8×105 元.
Abstract
There was a large amount of accumulated water in the goaf above 92105 driving face.In order to ensure the safe construction of 92105 driving face,long-distance water exploration boreholes were constructed in 92013 belt roadway,and the accumulated water in 91105 goaf was discharged.During the exploration of water,a total of 7 boreholes were constructed.The test results show that after using advanced water exploration drilling,the advance of 92105 driving face can be ensured to be 552 m,saving 46 d of construction period and 4.8×105 yuan of cost.
