摘要
通过分析伊敏二矿水文地质条件,进行水害特征分析,确定影响15煤组安全开采含水层,针对15煤组含水层下安全开采工程背景,为了能够实现水体下的安全合理开采需求,基于GMS数值模拟软件,分析了拟疏干区域在不同含水层参数条件下伊敏二矿15煤组顶板砂岩含水层水头分布趋势和疏排情况,为水害防治提供技术支撑。
Based on the analysis of the hydrogeological conditions of Yimin No.2 mine and the analysis of the characteristics of water disaster, determines the influence on the safe mining of the aquifer under the aquifer of No.15 coal group, in order to meet the requirement of safe and reasonable mining under water, based on GMS numerical simulation software, analyzes the water head distribution and drainage of roof sandstone aquifer of No.15 coal group in Yimin No.2 mine area under different aquifer parameters,and provides theoretical support for water disaster prevention.
