九龙矿开采对地下水资源量影响研究

Study on the impact of mining in Jiulong Mine on groundwater resources

为了研究九龙矿开采对地下水资源影响,本文采用理论计算、资料分析及水位观察分析的方法,对九龙矿范围内地下水影响区做了计算,确定了九龙矿开采的导水裂隙带最大高度为64.77 m,垮落带最大高度为16.02 m。表明现状条件下,九龙矿开采对下石盒子组砂岩含水层、大煤顶板砂岩含水层、野青灰岩含水层、大青灰岩含水层影响严重,对第四系含水层及煤层下部奥陶系含水层影响较轻。

In order to study the impact of mining in Jiulong mine on groundwater resources,this paper used the methods of theoretical calculation,data analysis and water level observation and analysis to calculate the groundwater impact area in Jiulong mine.The maximum height of water conduction fracture zone was 64.77 m and the maximum height of caving zone was 16.02 m.It showed that under the current conditions,the mining of Jiulong Mine had a serious impact on the sandstone aquifer of the Lower Shihezi Formation,the sandstone aquifer of the large coal roof,the Yeqing limestone aquifer and the Daqing limestone aquifer,and had a slight impact on the Quaternary aquifer and the Ordovician aquifer under the coal seam.
