Research On Geological Environment Of Mine Area In Hunan

Our nation's economy is on the development stage with the main features depending on consuming a large number of natural resources, specially mineral resources. With the strength of mineral resources development is larger and larger, it is highlight day and day that the mine area geological environment problems affect on the quality of the ecological one. Based on the extensive collection achievement which have been gained at home and abroad, the thesis systematically divides the mine geological environment problems into different classifications by means of surveying the mine geological environment and dissecting the important mines in Hunan, promulgates the reason of forming mine geological environment problems and discusses the method and technology of harnessing them, applying on the theory of hydrogeology, engineering geology, environmental geology, environmental geochemistry and restoration ecology etc., and then puts forward the related suggestion of policies and measures.The mine geological environment problems can be mainly divided into the two kinds of the empty being excavated and piling up of the mine waste residue. The basic method of settling the mine geological environment problem is, at first, scientific planning and rational excavation, in order to avoid inducing the suddenly geological hazards of collapse, landslip, mud rock flow, surface subsidence, ground crack etc., the second, carrying out the excavation technology without waste residue, doing oneself best to reduce the output of waste residue and tailings, the third, implementing reclamation of mine land, recovering the ecosystem of the district, and realizing the harmonious development between human being and nature.The present situation of mine geological environment in Hunan is, the first time, all-side investigated. This thesis expounds the expression form, distribution characteristics and formation mechanism of geological hazards including collapse, landslip, mud rock flow, surface subsidence, ground crack etc. in mine area, apply theory of rock and soil mechanics...
