摘要
露天矿土地破坏程度评价方法有很多,具有不确定性。本文以模糊数学为理论基础,建立了露天矿土地破坏评价的模糊综合评价体系。将土地破坏分为3级,给出露天矿土地破坏的影响因素,并应用G1法计算各因素的权重,采用公式法和专家评定法确定隶属函数及隶属度。将建立的模糊综合评价体系应用于某露天煤矿土地破坏分析,评价结果较好地反映了该露天矿的实际状态,表明该方法具有一定的实用性,为露天矿山土地破坏评价提供借鉴。
There are many uncertain evaluation methods on the destruction degree of surface mine land. In this paper based on the theory of fuzzy mathematics, a fuzzy comprehensive evaluation system for stability analysis of the open mine slope was established. stability degree of slope was divided into three levels, and the factors affecting the stability of the slope were given. Their ~veights were calculated by using the method G1, and the membership function and membership were determined by applying both formula method and expert evaluation method. The stability of slope in a surface mine was evaluated by using the system, and the evaluation results were in good agreement with the actue.l situation. It is shown that the method has certain practicability and can provide a guideline for similar projects.
