复杂地质条件过塌孔技术探讨与实践

摘要

通过对新桥煤矿2101工作面G6号钻场过塌孔技术的研究，总结了塌孔下套管技术、塌孔注浆技术、塌孔透孔技术和三棱钻杆过软岩塌孔等一套行之有效的技术，为矿井后续过塌孔施工积累了成功的技术经验。%Based on the research drilling through the collapse hole technology in Xinqiao Mine 2101 working face No. G6 drilling ifeld, summarized the casing technology and the grouting technique in the hole collapse, a set of effective technology drilling through the hole collapse in soft rock using the triangular drilling rod, and accumulated the successful experience drilling through collapse hole.
