Abstract: Taking slope unit as evaluation unit, through establishing the evaluation index system of three factors including regional geological environment background, resource damage and geological hazard, the evaluation indexes are quantified and weighted to make the zoning evaluation of mine geological environment in Xuchang City by layer overlapping analysis of GIS technology. The zoning results are consistent with the current survey, which verifies the practicability of the method and provides reference for planning and treatment of mine geological environment in the area.
