Due to the excessive mining and the lack of perfect and suitable mine restoration measures, some villages in Xintai area have coal goaf and karst collapse area. Through field investigation and public opinion survey, GIS(geographic information system)technology and Origin comprehensive three types of eight evaluation factors were used to evaluate the mine geological environment. With the engineering rock group stratigraphic lithology as the base map for the evaluation of the geological environment of Xintai major coal mining and hollowing township geological environment grade mapping, the results show that the mine environment in Xintai area is average. According to the evaluation results, targeted restoration and ecological management can be carried out in Xintai area according to the township as a unit. After using GIS and Origin and synergy matrixcalculation methods to evaluate the mine environment of each township in Xintai area, it is found that the mine geological environment quality of Wennan Town is relatively the worst, and the evaluation grade is poor, while the results of other township grades are average. Mine ecological restoration and land ecological utilization are important environmental protection measures, and it is recommended to restore the mine environment, organize land and carry out urban planning through vegetation restoration and greening, soil improvement and conservation, rational use of water resources, protection of biodiversity, land reuse and comprehensive development, and structural gradient restoration.The research method can be applied to the geological environment assessment of other mines.
