在调查露采宕口现状的基础上,采用定性与定量相结合的层次分析法,建立系统评价的结构模型和数学模型。通过计算分级,确定矿山地质环境极差区、较差区和一般区的范围和面积。结果表明,该区山体地质环境质量总体较差,地质灾害隐患多。但经过适当的恢复治理,大多数宕口和矿山废弃土地可得到利用。 On the basis of investigating the status quo of opencast detention, the analytic hierarchy process with the combination of qualitative and quantitative methods was used to establish the structural model and mathematical model of systematic evaluation. Through the calculation of grading, determine the range and area of ​​the mine geological environment of poor area, poor area and general area. The results show that the quality of the mountainous geology environment is generally poor and there are many hidden dangers of geological disasters. However, after proper restoration and management, most dilapidated and abandoned mines can be used.
