2021年笏山矿难钻孔救援是我国钻孔救援成功的典型案例。由于地层坚硬且裂隙发育，导致钻孔易偏斜且易发生卡钻事故，针对这一特殊情况采用潜孔锤空气泡沫钻进及螺杆马达纠偏等钻进工艺，成功完成了小口径生命保障孔钻探救援任务，同时本文也对生命保障孔、排水孔和大口径救生孔钻探救援技术进行了总结，对今后开展钻孔救援工作提出有待改进的问题和建议。
The drilling rescue in 2021 Hushan mine disaster is a typical case of successful borehole rescue in China. The hard formation and fracture easily lead to borehole deflection and sticking accidents. For this special condition， some drilling technologies such as DTH hammer air foam drilling and PDM deviation correction drilling was used to successfully complete the drilling rescue mission of the small diameter life support hole. This paper also summarizes the drilling rescue technologies for the life support hole， the drainage hole and the large diameter rescue hole， and puts forward some suggestions and problems on improving rescue work in the future.
