【摘要】：針對(duì)淮北礦區(qū)臥龍湖煤礦8101工作面涌水水量大、持續(xù)時(shí)間長(zhǎng)的問題,為了判別其涌水水源,首先從巖性結(jié)構(gòu)特征、地質(zhì)構(gòu)造特征等方面,利用模糊聚類方法,對(duì)區(qū)內(nèi)二疊系上石盒子組底部(K3)砂巖含水層的富水性進(jìn)行綜合評(píng)價(jià);然后對(duì)比分析相鄰礦井的涌水和水文地球化學(xué)特征。利用多種方法綜合研究表明:礦區(qū)北部砂巖富水性強(qiáng),工作面直接涌水水源為K3砂巖含水層,該含水層與附近礦井砂巖水之間存在水力聯(lián)系,具有共同的水源,礦區(qū)北部受到了外來水源的補(bǔ)給。
[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.
