根据金属矿山地下开采对地面沉降影响的因素构建了影响地面沉降评价指标体系,分别借助Fuzzy AHP法和中心点三角白化权函数确定各指标权重和隶属度,建立了金属矿山地表沉降模糊综合评价模型.运用此模糊综合评价模型对江西某矿地下开采引发地表沉降进行了评价.
According to the factors affecting the ground subsidence, the index system of land subsidence evaluation is established according to the influence of underground mining on the ground subsidence. The weight and membership degree of each index are determined by fuzzy AHP method and the center point trigonometric whitening weight function respectively. The fuzzy comprehensive evaluation model This fuzzy comprehensive evaluation model was used to evaluate the surface subsidence caused by underground mining in Jiangxi Province.
