| 摘 要： | 结合邻区矿井开采数据,对井田内地形地貌、构造、地表水以及地下水等水文地质特征进行分析研究,认为井田水文地质条件简单,地表水、老窑水对矿井开采影响不大,断层导水性弱,渗透途径为冒落裂隙带;矿井初期开采煤层时直接充水水源为长兴组、大隆组等岩溶裂隙水、龙潭组砂岩裂隙水,其次为老窑积水,充水通道为冒落裂隙带;中后期开采时,直接充水水源为大气降水以及河流、溪沟水。由于峨眉山玄岩的阻隔,茅口组强含水层对矿井开采没有影响。

| Abstract: | Combining with neighboring coalmine mining data, analyzed minefield relief and landform, structure, surface water and groundwater hydrogeological features, considered that the hydrogeological condition in the minefield is simple, no major surface water, gob water impacts to coal mining; transmissibility of fault is weak, path of filtration is caving fracture zones. Initial mining stage direct water filling sources are from Changxing, Dalong formations karstic fissure water, Longtan Formation sandstone fissure water, the second is gob water, water filling channel is caving fracture zones. Middle and later mining stages direct water filling sources have atmospheric precipitation and river, creek water. Because of obstruct by the Emeishan basalt, no impact from strong Maokou Formation aquifer at all. |
