随着矿山开采向外部和深部扩展,对矿区环境地质的影响愈来愈强烈,尤其在岩溶矿区,超量地疏排地下水,大范围地降低地下水位标高,其环境地质灾害问题更为突出,这不仅严重制约着矿产资源的开发和利用及矿业经济的可持续发展,更给矿山开采带来了巨大的安全隐患。 As the exploitation of the mine expands to the outside and deep, the impact on the environmental geology of the mining area becomes more and more intense. Especially in the karst mining area, the groundwater is excessively discharged and the elevation of the groundwater level is lowered in a large scale. The problem of environmental geological disasters is more prominent, This not only severely restricts the development and utilization of mineral resources and the sustainable development of the mining economy, but also poses a huge security risk to the mining.
