北皂矿区是我国唯一实施海下采煤的矿井,海域钻探的复杂性和特殊性,给钻探工作提出了严格的要求,针对北皂矿区海域下的地质条件,为了提高工作效率和保证施工安全,应用螺旋钻进工艺进行海域钻探,探索新型海域钻探的施工方案,形成了一套稳定的施工工艺,为海域下钻探工艺提供借鉴意义,施工效率和施工能力大幅提高。
Beizao Mining Area is the only mine that implements coal mining in the sea in our country. The complexity and specialty of drilling in the sea area put forward strict requirements for the drilling work. In order to improve the working efficiency and ensure the construction safety in the sea area under Beizao Mining Area, , The application of auger drilling technology for drilling in the sea area and exploring the construction program of a new type of sea drilling has formed a set of stable construction technology which can provide reference for drilling technology in the sea area and the construction efficiency and construction capacity are greatly improved.
