摘要
介绍了青松井田的概况,结合断层带、矿井的水文地质特征分析,对矿井的充水因素进行了论述,认为矿区的主要充水水源为新生界松散层第四系及古滑坡孔隙水、二叠系煤系地层砂岩裂隙水、采空区老窑积水,充水通道主要为断层破碎带和采矿冒落裂隙带。由于峨眉山玄武岩的阻隔,茅口组灰岩强含水层对矿井开采没有影响。矿床属裂隙充水为主、水文地质条件中等的矿床。
This paper introduced the general circumstance of Qingsong minefield, combining with hydrogeological feature analysis of faulted zone and mine, mine water filling factors had been discussed, Cenozoic loose bed Quaternary, ancient landslide pore water, Permian coal-bearing strata sandstone fissure water and mine worked-out area gob water are the main water filling sources, the main water filling channels mainly are the shattered fault zones and mining caving fracturation zones.Because the obstructing of Mountain Emei basalt, there is no impact on mining from strong Maokou Formation aquifer.The mineral deposit belongs to mainly fissure water filling and moderate hydrogeological condition mineral deposit.
