摘　　要：基于两种典型的采煤区影响程度评估方法,对比分析两种评估方法的结果,讨论二者的优缺点。研究结果表明:概率积分法和模糊综合评判法的采煤区影响程度划分结果存在明显差异。与模糊综合评判法相比,概率积分法的评价结果更为客观,理论体系更加成熟,但是其参数选取也存在的不足,建议根据参数反演选取预测参数。模糊综合评判法运用于采煤区影响程度分析存在缺陷,因子权重分配和影响程度隶属函数体系有待进一步完善。Two typical evaluation methods were carried out to comparatively analyze the influence degree caused by coal mining activities, advantages and disadvantages in regarding with methodologies were discussed as well. The results showed that significant differences of classification on influence degree between probability integral method （PIM） and fuzzy comprehensive evaluation method （FCEM） were identified. Comparing with FCEM, the evaluation results of PIM were more objective, the theoretical system was more perfect. But its parameter selection still exist defect, the suggestion is that parameters should be selected by parameters inversion. There were deficiencies in relating to the application of FCEM to analysis of influence degree at coal mining site, the distribution of factors weight and subordinate function system of influence degree need to be improved.
