露天矿土质破坏程度评价博弈-可拓模型

Open-pit mine soil damage evaluation based on the game theory and matter-extension model

为了解海州露天矿周边土质破坏情况,经过实地勘察和文献分析得出了土质破坏情况评价指标和等级,并提出了一种博弈-可拓模型对该问题进行评价.该模型利用可拓评价法确定评价指标体系并建立分级标准,得到经典域、节域和待评物元,确定关联函数;使用博弈论方法确定各指标权重;最后确定隶属等级.该算法优点在于:1可得到与相邻两个评价等级的趋近关系,以确定未来发展趋势;2可确定各因素指标的主观权重和客观权重.评价结果表明:海州露天矿土质破坏程度靠近Ⅱ级,且也略有向Ⅲ发展的倾向.

In order to understand the damage of the surrounding soil of Haizhou open-pit coal mine, the soil damage evaluation index and grade are obtained through field investigation and literature analysis. And a kind of the game-extension model is put forward to evaluate the problem. The extension evaluation method is used to determine the evaluation index system and establish the classification standard. The classical domain, joint domain and the matter-element are obtained, and the correlation function is determined. The game theory is used to determine the index weight, and the membership level finally. Advantages of this algorithm are that： 1） the available evaluation class and the adjacent two classes close relationship can be used to determine the future development trend. 2） Every factor index of subjective weight and objective weight are obtained. Evaluation results show that Huizhou open-pit coal mine soil damage near level II, and also to slightly level development tendency.
