阿刀亥煤矿水文地质条件与矿井突水研究

Hydrogeological Condition and Water Inrush Research in Adaohai Mine

对阿刀亥煤矿内水文地质条件进行调查和测试,分析探讨了矿区内地质构造与矿井水文条件的关联性。根据地层和水文资料将矿区含水层划分成四组:第四系冲洪积砂砾石层潜水层;侏罗系孔裂隙承压含水层组;石炭-二叠系孔裂隙承压含水层组;寒武-奥陶系裂隙、溶洞承压含水层。各含水层组由断层的导通作用发生水力联系,断层还是导致矿井突水的重要地质因素。

Hydrogeology condition on Adaohai Mine was investigated to obtain the relevance of geological structure and hydrogeological condition in the mine. According to the data of coal seams and hydrogeology, aquifers were divided into 4 groups： phreatic aquifer of alluvial-pluvial gravel layer in Quaternary system, bearing pressure aquifer of pores and fissures in Jurassic system, bearing pressure aquifer of pores and fissures in Permo-Carboniferous system, and bearing pressure aquifer of fissures and karst cave in Cambrian-ordovician system. Hydraulic connection happens under conduction effect of faults among the aquifers. Besides, fault is one of important factors causing water inrush in mines.
