摘要
晋城煤业集团赵庄煤矿二号井东回风立井井筒所穿越的基岩强风化带,虽然厚度不太大,但含水层较多,涌水量较大,水文地质条件复杂。本文简要介绍了复杂地质条件下,工作面深孔通过基岩风化带,并且保证优质工程的施工经验。
The imensively weathering zone of bedrock got through the shaft of eastern second well of Zhaozhuang Coal Mine, Jincheng Anthracite Coal Mining Group vertical air shaft of the on, although the thickness is not larger,the aquifer is more, the amourt of water dischargeing is larger and hy are complicated. The thesis simply expounds the construction experience of the face deep - hole through bedrock weathering zone, and insures the quality of perfect engineering.
