湘潭某大型锰矿矿区地面塌陷成因及危险性评估与防治策略
Causes,risk assessment and prevention strategies of ground collapse in a large manganese mine in Xiangtan
摘要
Abstract
To investigate the precise prevention and control measures for ground collapse in mining areas,the au-thors in this study selected Xiangtan Manganese mining area as the study object.Geological environmental,hydro-geological,and engineering geological data for the study area were collected to analyze the developmental charac-teristics,influencing factors,and genetic mechanisms of ground collapse.The factor matrices for susceptibility and risk assessments were established,according to the main control factors of karst collapse(stratigraphic litholo-gy,structure,overburden thickness,configuration and properties,hydrodynamic conditions)and the main control factors of goaf collapse(seam burial conditions,mining methods and mining degree,groundwater,faults).And susceptibility and risk assessments for karst collapse and goaf collapse were conducted,and targeted prevention and control measures were proposed.The results show that the study area contains 3 high risk areas of karst col-lapse,which can be treated by ground filling for cracks and collapse holes,grouting and filling of underground karst regions.Additionally,there are 8 high risk areas of goaf collapse that require reducing pumping and drain-age volumes,managing water level fluctuations,and implementing curtain grouting or backfilling and water filling if necessary.The research results could provide references for the prevention and control of ground collapse in Xiangtan Manganese mining area,serving as a guide for risk assessment of ground collapse in other areas.关键词
