【摘要】：针对淮北矿区卧龙湖煤矿8101工作面涌水水量大、持续时间长的问题,为了判别其涌水水源,首先从岩性结构特征、地质构造特征等方面,利用模糊聚类方法,对区内二叠系上石盒子组底部(K3)砂岩含水层的富水性进行综合评价;然后对比分析相邻矿井的涌水和水文地球化学特征。利用多种方法综合研究表明:矿区北部砂岩富水性强,工作面直接涌水水源为K3砂岩含水层,该含水层与附近矿井砂岩水之间存在水力联系,具有共同的水源,矿区北部受到了外来水源的补给。
[Abstract]:In view of the problem of large water inflow and long duration in 8101 face of Wolong Lake Coal Mine in Huaibei mining area, in order to distinguish the water source of water gushing, the fuzzy clustering method is used in the aspects of lithologic structure, geological structure and so on. The water enrichment of the bottom (K3) sandstone aquifer of the Upper Shihezi formation in the Permian region is evaluated synthetically. Then, the characteristics of water gushing and hydrogeochemistry of adjacent mines are compared and analyzed. The comprehensive study of various methods shows that the sandstone in the northern part of the mining area is rich in water, and the direct water inflow water source is K _ 3 sandstone aquifer. There is a hydraulic connection between the aquifer and the nearby mine sandstone water, and there is a common source of water. The northern part of the mine is supplied with foreign water.
