摘要
Bainiuchang Ag-polymetallic mining area is situated in the Dehouhe hydrogeological unit and supply area in east side of head water of Honghe river drainage system and Nanpanjiang river drainage system belongning to Honghe river drainage system.In order to keep safe and quick mining the water filling channel and types of water filled is required to be analyzed.Based on investigation of hydrogeological condition and detail water-filling factors analysis it is considered that the structurally cataclastic zone is the main channel,atmospheric precipitation,ground water,surface water the main types of water filled.Groundwater is the main source,meteoric rainfall and surface water are the influencing factors of the water filling.The deposit is of mediumj-complex karst fissure water-filling condition.Water is filled both from roof and bottom and risk is predicted during mining in rainy season and measures for preventing the water filling is put forward.
