Discussion on Hydrological Relationship of Main Aquifer and Minor Aquifer of Groundwater of Chambishi Copper Mine, Zambia
Xu Ning (Shandong Branch, China Aluminium Industry Co.)
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.
