Regionalization study of mine geological environment in Jiangsu

With the mining economic development from resources exploitation to exploitation and protection, mine geological environment protection and management have become the main content of ecoprovince construction. Therefore, a reasonable delineation of the mine geological environment protection and management areas is of major significance to improve the ecological environment. Based on the survey results of the Jiangsu mine geological environment, this article considers natural and social properties and establishes the regionalization of Jiangsu mine geological environment evaluation system, which includes 2 target layers, 5 layers and 12 index layers. Under the support of MAPGIS technique, using the comprehensive index model, each division factor is algebraic space stacked by their weights. According to the stacking result and mining situation, closed mining areas are divided into key management and general management of geological environment, while the mining areas are divided into the key prevention and cure ones and prevention and cure ones of geological environment.
