Analysis on Destruction Degree of Open Mine Land Based on Fuzzy Comprehensive Evaluation
There are many uncertain evaluation methods on the destruction degree of open 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.The stability degree of slope was divided into three levels, and the factors affecting the stability of the slope were given.Their weights were calculated by using the method Gl, and the membership function and membership were determined by applying both formula method and expert evaluation method.The stability of slope in an open mine was evaluated by using the system, and the evaluation results were in good agreement with the actual situation.It is shown that the method has certain practicability and can provide a guideline for similar projects.
