湖南南部,灰岩广布,有色金属矿床常产于其中,形成水文地质条件复杂的岩溶矿区类型.近年来,由于生产和勘探工作实践的需要,我们认为可将本岩溶矿区水文地质类型划分为裸露和隐伏两个亚类,由于二者水文地质特征不同,因而勘探方法也截然有别,但其对生产的危害性则是一样的.特别对裸露岩溶类型,当人们未认识其规律性时,误认为水文地质条件简单,因而可能造成人身死亡或生产停顿,这在湖南有的生产矿山是有教训的.
In southern Hunan, limestone widely distributed and non-ferrous metal deposits are commonly found in these areas, forming the types of karst mining areas with complex hydrogeological conditions.In recent years, due to the need of production and exploration work, we believe that the hydrogeological types of this karst mining area can be divided into Due to the different hydrogeological characteristics of the two sub-classes, the exploration methods are also quite different, but their harmfulness to production is the same, especially for exposed karst types, when people do not know their regularity , Mistakenly believe that the hydrogeological conditions are simple, which may cause personal death or pause in production. This is a lesson learned from the production of mines in Hunan Province.
