谢桥矿陷落柱影响区各含水层之间的水力联系研究

The Study on the Hydraulic Connection between the aquifers in the Region Affected by the Sink Holes of Xie-qiao Coal Mine

在谢桥矿的东翼采区存在1#和2#两个陷落柱,随着该矿向深部二水平拓展,A组煤开采受陷落柱的威胁越来越大,影响区内各含水层之间的水力联系显得越发重要。受陷落柱影响的灰岩地层主要为石炭系太原组、奥陶系和寒武系,本文就从两方面着手,对陷落柱影响区内各灰岩地层和煤系地层与灰岩地层之间的水力联系进行研究,其之间的水力联系情况对指导煤矿安全生产具有重大意义。

There are two sink holes of 1 # and 2# in East mining area of xieqiao mine, with the second level of the mine to expand to the deeper, A group of coal mining by the growing threat of collapse column, Hydraulic connection among the aquifers in the region aftected by the sink holes becomes more important. Limestone affected by the sink holes are mainly Carboniferous Limestone Taiyuan, Ordovician and Cambrian, this paper are two-pronged approach, studying hydraulic connection among limestones and between coal strata and limestones in the region, the hydraulic connection situation between them have a great significance to guide safety production of the coal mine.
