摘要
斜井开采为煤炭开采主要开拓方式之一,开采过程中会对矿区及其周边地下水产生影响,局部由于采煤产生地表裂隙,使井田范围内村民排放的生活污水、农灌污水和大气降雨通过这些裂隙进入浅层地下水,会对地下水水质产生一定的影响。以云南某煤矿斜井开采为例,在搜集、分析矿区及其周边水文地质与工程地质资料基础上,进行地下水监测、抽水资料分析、含水层地下水水位下降情况及地下水水位影响半径等分析计算,进行矿区开采对地下水环境影响预测,同时对相应的保护措施进行了探讨。
Inclined shaft mining for one of the main ways to develop the coal mining, mining process will have an impact on the mining area and its surrounding groundwater,local due to mining produce surface crack, the villagers to discharge ida within the scope of sewage, agricultural irrigation water and rainfall may enter the shallow groundwater through these cracks, will have a certain impact on groundwater quality. Taking a coal mine in Yunnan mining in inclined shaft as an example, in the collection, analysis, mining area and its surrounding engineering geological and hydrogeological data,groundwater monitoring, the data analysis, the aquifer decline of groundwater level and groundwater level influence radius calculation and analysis for mining, prediction of groundwater environment, at the same time, protection measures is also discussed.
