摘要
为了对井工煤矿区的地质环境风险进行量化分级与评价,研究过程识别了主要风险类型,并在其基础上归纳出地质环境风险的影响因素,包括自然地理条件、开采地质条件和工程条件。再运用层次分析法构建三级评价指标体系,为各级指标分配量化的权重值。最后基于多准则决策分析模型计算出煤矿的地质环境综合评价指数,根据该指数的分值确定煤矿地质环境的风险等级。经实测,该方法取得了良好的应用效果。
In order to quantitatively classify and evaluate the geological environmental risks in underground coal mine area,the main types of risks were identified during the research process,and based on this,the influencing factors of geological environmental risks were summarized,including natural geographical conditions,mining geological conditions,and engineering conditions.Further use the analytic hierarchy process to construct a three-level evaluation index system and assign quantified weight values to each level of indicators.Finally,based on the multi-criteria decision analysis model,the comprehensive evaluation index of the geological environment of the coal mine was calculated,and the risk level of the geological environment of the coal mine was determined based on the score of this index.Through actual testing,this method has achieved good application results.
