- Abstract
To study the geological environment impact assessment and restoration of an abandoned open-pit mine in Longmen Mountain, and to explore the mode and technical measures of mine geological environment restoration. The influencing factors of the mine geological environment in the study area were analyzed, and the geological environment impact assessment of mine geological disasters, aquifer damage, landform landscape damage, and land damage carried out. The geological environment restoration and treatment zones of the mine were divided, and the geological environment restoration measures of abandoned open-pit mines were discussed. The mining geological hazards in the study area had little harm degree, little impact on the aquifer, and serious damage to landform landscape and land resources. The key control area of the mine geological environment is 6.47 hm², accounting for 17.80% of the total area, the second key control area is 9.73 hm², accounting for 26.77% of the total area, and the general control area is 20.15 hm² accounting for 55.43% of the total area. According to the evaluation results, the restoration measures of "slope dangerous rock clearing + landform remodeling + soil reconstruction + retaining wall + cut-off drainage channel + vegetation reconstruction + are adopted to restore the damaged landform landscape and land, and good restoration effects can be achieved. The research results have certain reference significance for the geological environment impact assessment and restoration research of the same type of open-pit mine.
