矿山地面塌陷区地质灾害风险模糊综合监测方法

为了获取塌陷区地质灾害风险指数，判断风险程度，提出一种矿山地面塌陷区地质灾害风险模糊综合监测方法。初选指标后，利用相关系数法和偏最小二乘法再选指标，构建评价指标体系；利用层次分析法和因子分析法计算选出的评价指标的综合权重；计算指标权重与模糊隶属矩阵之间的乘积，得出矿山地面塌陷区地质灾害风险模糊综合监测指数，对比评价等级表，划分地质灾害风险等级。结果表明：利用所研究方法划分了某煤矿区1区为高风险区，3区、4区为中风险区，7区、6区、2区为低风险区，5区为极低风险区，完成了矿山地面塌陷区地质灾害风险模糊综合监测，为防治策略的提出提供可靠的依据。

Fuzzy comprehensive monitoring method for geological disaster risk in mine ground subsidence area

In order to obtain the geological disaster risk index of subsidence area and judge the risk degree, a fuzzy comprehensive monitoring method for geological disaster risk in mine ground subsidence area is proposed. After the primary selection of the indicators, the correlation coefficient method and partial least square method are used to re select the indicators to construct the evaluation index system; The comprehensive weight of the selected evaluation indexes is calculated by analytic hierarchy process and factor analysis; Calculate the product between the index weight and the fuzzy membership matrix, obtain the fuzzy comprehensive monitoring index of geological disaster risk in mine ground subsidence area, compare the evaluation grade table, and divide the geological disaster risk grade. The results show that the research method is used to divide a coal mine area. Area 1 is a high-risk area, area 3 and 4 are medium risk areas, area 7, area 6 and area 2 are low-risk areas, and area 5 is a very low-risk area. The fuzzy comprehensive monitoring of geological disaster risk in mine ground collapse area is completed, which provides a reliable basis for putting forward prevention and control strategies.
