超前探放防治水技术在相邻采区中的应用

Application of Advanced Exploration and Release of Prevention and Control Water Technology in Adjacent Mining Area

为了解决潘津工业煤矿2302采空区存在积水,威胁相邻的2303切眼工作面与轨道顺槽的水害问题,通过采用超前探放防治水技术,在2303切眼工作面布置三个钻孔对2302采空区进行放水,三个钻孔累计放水50158 m^(3)。根据放水的实际情况以及4^(#)钻孔验证的结果,采用超前探放防治水技术可成功地解决2302采空区威胁2303回采面安全的水害问题。

In order to solve the problem of water hazard in the 2302 goaf of Panjin Industrial Coal Mine,which threatens the adjacent 2303 cutting face and track trough,by using advanced exploration and discharge water prevention and control technology,three boreholes are arranged in the 2303 cutting face to discharge water in the 2302 goaf,and cumulative discharge of water from three boreholes is 50158 m^(3).According to the actual situation of water discharge and the verification results of the 4^(#)drilling hole,the water hazard problem of the 2302 goaf threatening the safety of the 2303 mining face can be successfully solved by using advanced exploration and release of prevention and control water technology.
