基于三角模糊数的AHP-TOPSIS村庄下开采接续方案优选方法研究

Research on preferred method of connecting mining village based on AHP-TOPSIS of triangular fuzzy numbers

为了研究在保证出煤量的条件下最大程度地减少采空区对村庄建筑的损害,合理安排采煤接续方案的问题,采用综合层次分析法(AHP)和逼近理想解排序法(TOPSIS)的基础上引入模糊数学理论,建立了村庄下采煤地表建筑物损坏的模糊评价模型,解决了多属性评价指标融合问题和评价指标过硬问题。以辽源矿区龙家堡煤矿村庄下孤岛煤柱开采为例实施了该理论,同时与已有的两种方案选择方法得到的结果进行了比较。分析结果表明,在各备选方案中接续205工作面为最优备选方案。该方法的最大优势在于三角模糊数对评判数据的模糊化,同时计算量也较小。

In order to have reasonable arrangements of continuation of mining program, guarantee the quantity of coal and at the same time to ensure the maximum damage of reduction in mined-out area of the village buildings, based on the adoption of comprehensive analytic hierarchy process （AHP） combining with ideal solution（TOPSIS）, this paper introduced the theory of fuzzy mathematics, established fuzzy evaluation model of the surface buildings damage in mined-out villages. It solved the multi- ple-attribute evaluation problem and evaluation perfect fusion problem. Taking pillar mining coal of isolated island in Long Jiapu coal mine of Liaoyuan mining area as an example to implement this theory achievement. At the same time,it compared the existing two methods of scheme selection results with the method. The results show that continue mining the No. 205 coal mining face is the best choice of all the alternatives. The biggest advantage of the method is that the evaluation data is fuzzy by the triangle fuzzy number, and has small amount of calculation.
