中文摘要：

针对母杜柴登煤矿巷道掘进进度与常规超前探放水在时间上的冲突,提出采用千米定向钻机进行超前探放水的方法,介绍了千米定向钻孔的设计与施工,并结合其在实际应用中的特性,总结出千米钻机在高压含水层的超前探放水中具有效率高和费用较低等优点,实现了千米钻机在高压含水层的超前探放水工作中的技术突破,具有一定的借鉴意义。

英文摘要：

According to a conflict between a mine roadway heading schedule and a conventional advance water exploration and drainage in Mudu Chaideng Mine,a 1000 m directional drilling machine was provided to an advance water exploration and drainage method. The paper introduced a design and construction of the 1000 m directional drilling machine. In combination with actual application features,the paper summarized high efficiency,low cost and other advantages of the1000 m directional drilling machine in the advance water exploration and drainage of a high pressurized aquifer. A technical breakthrough of the 1000 m directional drilling was realized in the advance water exploration and drainage of the high pressurized aquifer and would have certain reference significances.
