煤矿开采土地破坏程度的模糊综合评价

摘要

With the increasing coal mining,it has the enormous influence on the environment,especially on the land resources.Through the analysis of the factors,which affect on the land destructiveness for coal mining,the text chooses evaluation factors that are ground surface subsidence,inclination deformation,horizontal deformation and phreatic water level,adopts the fuzzy comprehensive evaluation model,confirms the land destructiveness grade in Huainan Li Village coal mining seam one and seam two.And the results not only verify the applicability of fuzzy comprehensive evaluation model,and also provide the theory basis for land resources＇ protection.%随着煤炭资源的日益开采,其对环境也造成了巨大的影响,其中对于土地资源的破坏尤为严重。通过分析影响煤矿开采土地破坏程度的因子,选择地表下沉、倾斜变形、水平变形和潜水位埋深作为评价因子,采用模糊综合评判模型,分别对淮南李庄煤矿采区一与采区二的开采对土地破坏程度的等级进行了确定,其土地破坏程度确定的结果不仅验证了模糊数学评判模型的适用性,也为该矿区的土地资源保护提供了理论依据。
