摘要
根据望田煤矿的地质情况,计算煤层开采后形成的冒落带和裂缝带的高度以及煤矿开采排水导致地下水位降落漏斗分布范围,分析煤层开采对上部和下部含水层以及村民用水的影响,预测评估了2011-2015年采矿活动对地下含水层的影响。
After analyzing the geological features of Wangtian Coal Mine,the paper calculates the height of caving zone and fractured zone that formed after coal mining;with the analysis of the impact of mining on the upper and lower aquifers,the paper calculates the funnel-like distribution range formed after the groundwater level depressing which results from the mining drainage.And then the paper estimates the impacts of coal mining activities on underground aquifers in 2011-2015.
