| The mining industry has occupied an increasingly important position in the national economy.However,due to historical reasons and technical restrictions,many mines have been abandoned after resource exploitation and production.Due to years of human engineering activities and natural activities,these abandoned mines have brought a lot of geological environment problems,and have formed a large area of exposed land and a large number of untreated wastes such as slag and ore,which have seriously damaged the local environment and ecology and limited the local economic development.The wastes produced by these mine wastes have caused serious pollution and damage to the environment such as soil,water source and atmosphere.A large number of unstable and dangerous rock masses formed by mining are easy to cause geological disasters(hidden dangers)of collapse,which will bring great harm to people’s lives and ecological environment.The purpose of this paper is to take abandoned mines in Fup Ping County as an example,to fully understand the impact of abandoned mines on the eco-geological environment,to explore the main geological environment problems of abandoned mines and the design of ecological environment restoration projects.This paper mainly includes the following research contents:The basic situation of abandoned mines in Fu Ping County was investigated and collected,and the physical and mechanical properties of rock and soil were sampled and analyzed.The main geological environment problems of abandoned mines are investigated and analyzed,and the main forming factors of different problems are studied and summarized.Through the analysis of the characteristics of soil and vegetation in mining areas and combined with the theoretical analysis of ecological restoration,control measures proposed for diverse geological circumstance issues.Research and analysis of ecological restoration literature,the safety and stability of abandoned mines are analyzed and evaluated,and the overall restoration project design of abandoned mines in the governance area is put forward.CASS software is used to analyze and calculate the volume of excavation,filling and dressing of abandoned mines,and Sketchup is used to design each sub-project of ecological restoration in detail.To sum up,this paper analyzes the geological environment problems of abandoned limestone mines in Fuping County,Shaanxi Province,and systematically studies the control measures of geological environment problems and the overall design of ecological restoration projects.This study provides a comprehensive idea and research direction for geological environment management and ecological restoration engineering design of abandoned mines in Fuping County and even the Yellow River Basin,and promotes regional economic and social development. |
