| A series of mining-induced environmental problems threaten the lives and property of people, and seriously affect and constrain the development of economy. On the basis of investigation and research at the mine geological environment, this article evaluates the quality of the mine geological environment and determines the most important environmental geological problems.(1)In the evaluation methods, the main results are:①This paper use square grid unit method to ensure the comparability of evaluation results.②Based on the requirements of evaluation targets and the development situation of the study area, my mine geological environment evaluation system include two layers: elements layer and index layer that ensure factors are comprehensive and objective.③This article select element index weighted factor scores comprehensive evaluation model that include single-factor evaluation, elements evaluation and comprehensive evaluation.④The index weight use analytic hierarchy process to avoid a certain amount of subjectivity.⑤Finally, the remote sensing survey results are quantitative analyzed in accordance with the evaluation model based on MAPGIS software and we get objective results.(2)Based on the evaluation results, we get:①Environmental issues of the study area distribute along the north-east, and with the increased mining activities, there is a trend to expand on both sides, so it should step up monitoring.②From the single-factor evaluation, the potential types are ground collapse, accumulation of solid waste and dust pollution that threat villages and roads.③In the serious problem area, for the region of residents and important traffic it should control the exploitation of mine in order to guarantee the quality of living environment.④The environmental problems at the junction should be strengthen managed to avoid no one is responsible for the problems.
