冯记沟煤矿地处西部干旱区,地表水及地下水极为贫乏。矿井井下的主要含水区段为侏罗系直罗砂岩含水层(Ⅱ)、一煤--六煤砂岩含水层(Ⅲ)和釆空区积水。现生产二号井煤矿开采过程中,由于三煤层顶板的垮落,裂隙增加,III含水层与II含水层连为一体。目前二号井的正常涌水量为115m3/h,最大涌水量280m3/h。根据勘探资料及水质分析结果,对矿区地下水进行了评价,认为矿井地下水不宜作生活饮用水,处理后可做为锅炉用水、冷却用水、绿化灌溉用水及混凝土建筑用水。
Fengjiugou mine is located in the western arid region, surface water and groundwater is extremely poor. The main water-bearing sections of the mine shaft are the Jurassic straight-lobed sandstone aquifer (Ⅱ), the coal-six-coal sandstone aquifer (Ⅲ) and the water from the beacon area. In the production of No.2 well coal mine, the III aquifer is connected with the II aquifer due to the collapse of the roof of the third coal seam and the increase of fractures. At present, the normal water inflow of No. 2 well is 115m3 / h and the maximum water inflow is 280m3 / h. According to the exploration data and water quality analysis results, groundwater in the mine area was evaluated, that mine groundwater should not be used for drinking water, after treatment can be used as boiler water, cooling water, green irrigation water and concrete construction water.
