摘要
Abstract
The Lancang Lead Mining Area in Yunnan is located at the junction of the Indian Plate and the South China Plate,featuring complex geological structures.Deep hydrogeological conditions restrict the safe mining of the mine.Based on geological exploration and hydrogeological survey methods,the deep hydrogeological characteristics of the mining area were investigated.The results show that the deep groundwater system of the mining area takes carbonate karst-fractured aquifers as its core,and fault structures such as F1,F3 and F11 exert a remarkable controlling effect on groundwater conduction.Karst development exhibits distinct zonal characteristics.In planar distribution,the karst density in the central and southern areas reaches 10～15 cavities/km2.Vertically,the cavity development rate within the elevation range of 1 680～1 850 m accounts for 83.3％of the total cavities revealed by drilling.Moreover,the degree of karst development decreases with increasing depth.This study provides a scientific basis for ensuring the safety of deep mining in the mining area.关键词
