对岩溶地区抽水排水所产生的地面沉降、开裂和塌陷,有关文献已作过不少的报道和研究;但是,讨论岩溶矿区由于疏干排水所引起的溶洞充填物突出的文章却不多见。溶洞充填物突出在南方岩溶矿区颇为多见,其所造成的灾害往往也相当严重。本文介绍湖南省几个岩溶矿区溶洞充填物突出的实例,并探讨其形成机理和防治方法,不当之处请批评指正。 There have been many reports and studies on ground subsidence, cracking and collapse caused by pumping and drainage in karst areas. However, it is rare to discuss the prominent cave filling in karst mining due to drainage and drainage. Karst cave filling prominent in the southern karst mining area is quite common, the disasters caused by them are often quite serious. This article introduces several cases of karst cave fillings in several karst mining areas in Hunan Province, and discusses its formation mechanism and prevention and cure method.
