申家庄煤矿扩大区水文地质条件分析

通过对申家庄煤矿扩大区2号煤层开采的水文地质条件分析，认为扩大区2煤以上各基岩含水层之间，分布有稳定的厚层粉砂岩和泥岩，构成良好的隔水层，且区内断层不导水，故2号煤以上各基岩含水层之间水力联系差，该区在原始状态下地下水不会对2号煤层开采造成影响，但在采动情况下水库水体对扩大区开采以及扩大区开采对水库有何影响还需进一步研究。

Hydrogeological Condition Analysis of Extended Area of the Shenjiazhuang Coalmine

Through the analysis of hydrogeological condition in No.2 coal seam in the extended area of Shenjiazhuang coalmine, considered that between various bedrock aquifers above No.2 coal seam existed steady and thick siltstone and mudstone layers and composing good confining beds. Besides, faults in the area are not water conducted, so that between bedrock aquifers above the No.2 coal seam have very poor hydraulic connection. Under original condition, groundwater in the area twill not affect coal mining, but have to have further studies on the relation between surface reservoir and mining in extended area during coalmine production.
