【摘要】 在阐述谦比希铜矿的地层和矿层赋存条件的基础上,分析了矿体含水层(副含水层)和上盘含水层(主含水层)的岩性特征,指出了上部石英岩隔水层的自身弱点,论述了沟通主副含水层的导水通道,这些通道包括:劈理、断层、构造薄弱带即角砾岩带、剪切带、节理和钻孔。根据500ML疏干主含水层和副含水层的放水孔的地下水涌水量做了统计分析结果,得出了只要把主含水层疏干副含水层就可以被疏干的结论。更多还原

【Abstract】 The rock properties of ore body aquifer (the minor aquifer) and upper rock aquifer (cherty dolomite, the main aquifer) are analyzed based on the occurrence conditions of strata and ore bed of Chambishi Copper Mine. The weak points of water-resistant layer of upper quartzite are pointed out. The water-diversion canals connecting the main aquifer and the minor aquifer are discussed. These canals include cleavage, fault, breccia, shear zone, joint and drilling. According to the statistic results of 500ML underground water in the drainage hole of both the main aquifer and the minor aquifer, it is concluded that the minor aquifer can be drained by draining the main aquifer.更多还原
