义安煤矿F_(29)断层富水性研究

Study on Water Abundance of F_(29) in Yi′an Coal Mine

为了弄清F29断层的富水性,采用井上下瞬变电磁探测、井下钻探探查等方法,并结合地面钻孔资料,通过对比分析研究,在进一步认定F29断层性质和特征的同时,对其富水性也有了明确的分析和验证,得出了F29断层弱富水这一结论,为矿井的防治水工作提供了依据。

In order to analyze the water abundance of F29 fault in Yian coal mine, surface underground transient electromagnetic exploration and drilling were applied in the research. Further analysis was done on characteristics of F29 combining with the surface drilling data, meanwhile, the water abundance of F29 was studied. Finally, the study indicated that the water abundance of F29 is weaker, and the result provides a basis for water hazard prevention and control.
