Mine environment evaluation in Anhui Province based on RS and GIS

Abstract

In order to understand the extent of damage to the environment and the scope of impact of mine development, using domestic high resolution satellite data, application of remote sensing and geographic information system technology, for comprehensive evaluation of the mining environment in Anhui Province, through the analytic hierarchy process, the quantitative analysis and zoning study of the mine environmental conditions are carried out, 16 evaluation factors were determined, and the comprehensive evaluation index model of mine geological environment was established, set comprehensive evaluation grade. Through analysis and research, the mining geological environment in Anhui Province is divided into four grades: seriously affected area, relatively seriously affected area, generally affected area and non-affected area. Field investigation and verification were carried out in the area seriously affected by the geological environment of the mine. The results showed that use of RS and GIS technology to carry out mine environment assessment in Anhui Province can more accurately reflect the extent of damage and scope of impact of mine development on the environment, and provide relatively reliable technical support and scientific basis for subsequent mine environment restoration and management.
