摘要
针对某矿区地层复杂、断层较多和以辉钼矿为主的特点,在施工过程中采用防塌泥浆、扩孔和扫孔工艺,有效地降低了事故率,提高了钻进效率。
With a view to complex strata, numerous faults and molybdenite based characteristics of the mine area, anti-slough mud, reaming and hole sweep process were used during the construction process. It turned out that the accident rate was effec tively reduced and the drilling efficiency was improved.
