A Study On Major Geological Disasters In Xiaoqinling Gold Mining Area And Prevention And Control Measures

The Lingbao Xiaoqinling gold mining area has great contributions to the economic development,but it has to face very prominent problems in the geological environments.The ecological environment in this area has been destroyed;land resources and landscape have been destroyed;and heavy metal pollution in the aquatic and soil environment are serious.In particular,the hidden danger of debris flow in mines is extremely serious.In this thesis,the author takes Xiaoqinling gold mining area of Zhuyang Town in Lingbao City as an example.Based on the investigation and analysis of mine geological disasters,mining areas,waste slag,etc.in this study area,the prevention and control countermeasures of major geological disasters are proposed.It provides geological basis and geotechnical parameters for geological disaster prevention and control analysis from engineering geological conditions such as stratigraphic structure,lithologic characteristics,and evenness.According to data collection,field surveys and indoor comprehensive analysis and research,the author focuses on the types,scale,causes and trends of major geological disasters in mines.The basic characteristics and the terrain conditions of geological disasters are analyzed.The factors affecting the stability of typical ballast slope are also evaluated.Finally,the author compares and analyzes the feasible countermeasures to the main geological hazards in mines.Through the stability analysis for the prevention and control engineering,debris flow calculation,and the results from other methods,the relevant parameters for the geological disaster prevention and control measures are provided..
