某矿山地质灾害模糊综合评价研究
|
摘要
采用GIS技术获取了某矿山地质灾害因子,建立了地形坡度、地层岩性与断层的层次结构模型。在此基础上,采用模糊综合评价方法对某矿山地质灾害进行了评价,定性地将评价区分为重度危险区、中度危险区与轻度危险区。基于地质灾害危险性基础因子与地质灾害危险性易损因子的地质灾害评价结果,得到某矿区重度危险区分别为6.7km~2与2.8km~2。研究结果对矿山地质灾害预测、防治具有一定的价值。
The geological hazard factors in a mine were obtained by GIS technique,and the hierarchical structure models of terrain slope,stratigraphic lithology and faults were established.On this basis,the fuzzy comprehensive evaluation method was used to evaluate the geological hazards,which qualitatively divided the evaluation areas into serious dangerous areas,moderate dangerous areas and mild dangerous areas.And based on the evaluation results of geological hazard basic risk factors and geological hazard risk vulnerability factors,the serious dangerous areas were respectively 6.7 km~2 and 2.8 km~2.The results were valuable for the prediction and prevention of mine geological hazards.
