中文摘要:2015年“12.25”平邑矿难钻孔救援是我国首例通过钻孔救生的成功案例。由于地层不断坍塌变形,导致了复杂地层条件的产生,给救援钻孔的施工带来极大困难。针对这一特殊情况,采用空气反循环钻井工艺技术,处理钻孔事故时采用气举反循环工艺技术。总结了大口径钻孔施工经验,对今后施工大口径救援钻孔提出有待改进的问题和建议。

Construction Technology of Large Diameter Rescue Borehole in Pingyi Gypsum Mine Disaster of Shandong
Abstract:The rescue of Pingyi mine disaster in Dec25. 2015 is the first successful rescue case by hole drilling in China. The continuous collapse and deformation result in complicated stratum conditions, which caused much difficulty to the rescue drilling hole construction. As to these special conditions, air reverse circulation drilling technology was used; and airlift reverse circulation drilling technology was used to deal with drilling accidents. This paper summarizes the experience of large diameter drilling construction and puts forward some problems to be improved in the future.
