云南白牛厂银多金属矿水文地质特征及其水害的预测与防治

云南白牛厂银多金属矿区位于红河与南盘江两大水系分水岭东侧的德厚河水文地质单元的补给区,属红河流域。为确保矿山的安全高效开采,须对矿床的充水通道、充水因素等进行分析。通过对云南白牛厂银多金属矿进行水文地质条件调查,详细分析矿区的水文地质特征,认为矿区充水通道主要为矿区的构造破碎带;矿床充水因素主要为大气降水、地下水、地表水:地下水是矿床充水的主要水源,大气降水与地表水是矿床充水的影响因素;该矿床为顶板和地板直接充水的水文地质条件中等-复杂的岩溶裂隙含水层充水矿床。预测了矿山开采可能会遇到的危险(如雨季发生突水等),提出了防治措施及建议。

Hydrogeological characteristics and water disaster prediction and prevention in Bainiuchang silver polymetallic deposit, Yunnan

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.
