和什托洛盖和什东-沙吉海矿区水文地质特征

为了查明沙吉海矿区水文地质特征，在对区域水文地质条件的分析基础之上，采用水文地质钻探、抽水试验及长期动态观测孔等手段，查明了矿区内的水文地质条件，矿区内主要的充水含水层为侏罗纪头屯河组孔隙微裂隙含水层、西山窑组孔隙裂隙含水层及烧变岩裂隙含水层，对煤层开采有影响的含水层主要为西山窑组孔隙裂隙含水层。查明其水文地质特征对于煤矿的安全生产有至关重要的作用，也对煤矿防治水起指导性作用。

Hydrogeological Characteristics of Heshentuoluogai and Heshendong-Shajihai Mine Area

In order to find out hydrogeological characteristics of Shajihai mine area, based on analysis of regional hydrogeological conditions, by means of hydrogeological drilling, pumping test and long-term dynamic observation holes, hydrogeological conditions of the mine in the mining area have been found out. Main water filling aquifers are pore and micro fracture aquifer in Jurassic Toutunhe formation, pore and fissure aquifer and burnt rock fissure aquifer in Xishanyao formation. Aquifer which will affect coal mining is mainly pore and fracture aquifer in Xishanyao formation. Identification of hydrogeological characteristics not only has an important role for safety production in coal mine, but also will guide water prevention and control effectively.
