摘要
通过本次研究工作,详细查明了研究区Ⅱ_(2a)煤层顶板含水层分布规律、埋藏条件及水力联系情况,根据邻矿的相似情况及实际经验进行类比分析,并且建立回归模型,得出计算综放开采条件下的冒裂带高度预计公式。利用邻区水文地质资料及本区水文孔抽水试验资料,采用了数值法分别对研究区进行涌水量计算,得到的结果和实测的数据基本吻合,这对矿井防治水有重要的意义,同时对煤层安全开采防治水条件进行了分析。
Through this research work, the distribution law, burial conditions and hydraulic connection of roof aquifer in Ⅱ2a coal seam in the study area are found out in detail. According to the similar situation and practical experience of adjacent mines, the analogy analysis is carried out, and the regression model is established. The prediction formula of the height of the caving zone under the condition of fully mechanized top coal caving mining is obtained. Based on the hydrogeological data of adjacent areas and the pumping test data of hydrological holes in this area, the numerical method is used to calculate the water inflow in the study area respectively. The results obtained are in good agreement with the measured data, which is of great significance to the prevention and control of water in mines. At the same time, the waterproof treatment conditions of coal seam safety mining are analyzed.
