Analysis of Deep Hydrogeological Characteristics and Water Filling Factors of the Datuanshan Deposit in Dongguashan Copper Mine
Through the analysis of the hydrogeological characteristics and genesis of the deep(-730m～-1000m)and 36A～43 lines of the Datuanshan copper deposit in Dongguashan,the study shows that the main ore body of this deposit is located below the local erosion benchmark,and the terrain is favorable for precipitation discharge.Surface water does not constitute the main water filling factor of the deposit.The underground water of the deposit mainly exists at a depth of-200 meters or more,with karst fissures containing water.The main aquifer is the Triassic carbonate rock,with a moderate to weak degree of water abundance.The groundwater in the ore deposit is replenished by precipitation,and the deep groundwater locally receives recharge from upper overflow and axial deep groundwater runoff.
