在易损性概念的基础上,明确矿区整体工业环境易损性的内涵。从地表工业环境、地下工业环境及矿区安全和环保状况3个层面出发,构建了矿区工业环境易损性综合评判体系。采用KullbackLeibler距离(即相对熵)计算评判对象与正理想解的贴近度,结合逼近理想解排序法(TOPSIS)思想建立KL-TOPSIS评判体系,对某煤矿2008—2013年的矿区工业环境易损性进行了综合评判。结果表明,2008—2010年易损度逐渐增至最大,之后到2013年又减至最小,期间略有波动。根据评判结果分析了易损度变化的原因,并提出了削弱易损性的合理化建议。
On the basis of the concept of vulnerability, the connotation of the fragility of the overall industrial environment in the mining area is clarified. From three aspects of the surface industrial environment, the underground industrial environment and the safety and environmental protection of the mining area, a comprehensive evaluation system of industrial environmental vulnerability in the mining area was constructed. The KullbackLeibler distance (ie, relative entropy) is used to calculate the closeness between the object of assessment and the positive ideal solution. The KL-TOPSIS evaluation system is established based on TOPSIS, and the vulnerability of industrial mine environment in a coal mine in 2008-2013 is analyzed. Conducted a comprehensive evaluation. The results show that the vulnerability gradually increased from 2008 to 2010 to the maximum and then to the minimum again in 2013 with a slight fluctuation. According to the result of the judgment, the reasons of the change of vulnerability are analyzed, and the reasonable suggestions to reduce the vulnerability are put forward.
