Analysis of mining technical condition of a certain Pb-Zn deposit in Tibet

Through surpassing 5000 m in the average elevation high and cold oxygen deficit mining area establishment simple weather stations, flow measurement section and the ground survey, catalog tunnel, water and groundwater observations, Preliminary identification of the deposit, the main aquifer water-filled fracture zone and construction of water-based weak-rich, poor groundwater recharge, hydro-geological conditions of a simple type;the mining lithology combination of more stable geological structure is simple, is not easy to have an adverse engineering geological problems; mining may be varying degrees of damage to fragile natural environment, surface water and groundwater of minor contamination.
