铝土矿地下开采水害分析

Study on water bursts of bauxite mines underground mining

地下开采铝土矿是我国铝土矿山的必然选择和发展趋势。水害是要面对的主要威胁之一,根据突水水源、采掘方式、岩体结构、突水形式和突水量等,对铝土矿地下开采中的水害进行了分类,说明了其特征。结合段村—雷沟铝土矿,根据勘探资料以及矿区地质与水文地质条件,段村—雷沟铝土矿的水害类型有地表水水害、冲积层水水害、岩溶水水害、断层水水害和采空区积水水害,论述了段村—雷沟铝土矿的水害类型及其对矿山建设的影响,分析了其成因,给出了该铝土矿山防治水害的总体思路和原则。

Underground mining is an inexorable trend and choice of bauxite resource in China, water bursts is one of the main disasters which is needed to faced during mining. The classifications and features of water bursts in bauxite mines mining is given according to the water resources, mining technique, rock mass structures, water inrush patterns and amount et al. With an example, Duancun-Leigou bauxite mine which sits in the west of Henan Province in China, water bursts classifications and the effects on the bauxite mine building are analyzed according to the water resources, the mechanism of the water bursts is explained. Water disaters prevention and cure of Duancun-Leigou bauxite mine are pointed.
