我国的大水矿山在防治水工作中积累了许多好经验。本文将结合广东石绿铜矿矿床疏干实例,探讨在岩溶大水矿床应用地表疏干方法的优越性。目前国内采用此种方法降低矿坑地下水位的矿山尚少,在国外应用地表疏干矿床地下水 China’s large water mines have accumulated a great deal of good experience in water control work. In this paper, we will combine with the example of Dredging of Shihchuan copper deposit in Guangdong to discuss the superiority of surface dredging method applied in karst water deposit. At present, there are still few mines in China that use this method to reduce the groundwater level in mines and groundwater from surface dry mines in foreign countries
