摘要
针对矿井施工探放水钻孔时因故障停电或突然打中高压水区,无法通过起拔钻杆关闭钻孔截止阀封堵钻孔水的难题,研制了液压钻机探放水钻孔密封装置,实现了在不起拔钻杆的情况下快速封堵钻孔水。现场应用证明,该装置具有较高的可靠性,可以确保探放水安全施工。
When the phenomenon power failure or suddenly hit the high pressure water zone appear in the process of constructing water drainage boreholes,closing stop valve was unable to plugging of drilling water by pulling out the drill pipe. Aiming at this problem,borehole sealing device in exploration and drainage of hydraulic drillhole drilling was developed in the paper. It can realize the quick plugging of drilling water in the case of not pulling out the drill pipe. The field application shows that the device has high reliability,and it can ensure the safety of the construction.
