察哈素煤矿井筒穿过含水软岩地层综合治理技术研究

Research on Synthetical Control Technology of Pit Shaft Passing Through Soft Aquifer in Chahasu Coalmine

察哈素煤矿发育有厚度不等的中生代白垩系下统志丹群含水软岩地层,如何安全经济地穿过它是井筒施工需要解决的主要问题。在对察哈素煤矿志丹群水文地质工程地质特征分析的基础上,通过技术经济比较,提出了预疏降治水方案和井筒穿过志丹群的安全技术措施,可为类似条件矿井的建井提供参考。

Chahasu Coalmine is developed with different thickness Zhidan group soft ground water ranging from Mesozoic Cretaceous aquife and how to safely and economically pass through them in shaft construction is the main problem needed to be solved. Based on analysis of the hydrogcology and geological features of Chahasu Coalmine and the technical and economic comparison, this paper proposes pro - dcwatexing water control methods and safety technical measures of pit shaft passing through Zhidan group, which can provide references for mine shaft construction in similar conditions.
