Gray-FAHP集成法在矿井瓦斯安全评价中的应用

Application of Gray-FAHP integration method to mine gas safety evaluation

为解决传统安全评价方法存在的推理速度慢、精度较低等问题,从影响瓦斯安全性的各种因素出发,建立以瓦斯状态、矿井通风、监控监测、安全管理、引火源为主要因素的矿井瓦斯安全评价指标体系。依据模糊综合评价法、层次分析法、灰色关联度法,构建矿井瓦斯安全评价的数学模型。运用该集成模型对黑龙江省龙煤集团鸡西分公司5个煤矿进行矿井瓦斯安全评价。结果显示,5个矿井瓦斯安全性均处于良好水平,按其程度排序,依次为煤矿1、煤矿4、煤矿5、煤矿3、煤矿2。该研究为煤矿瓦斯的安全性评价提供了一种新方法。

The efforts to overcome many shortcomings found in traditional security evaluation methods, such as slow reasoning and less accuracy resulted in the mine gas safety evaluation system which is targeted at the main factors, such as gas state, mine ventilation, monitoring, safety management and fire source, starting from all factors influencing gas safety. The mathematical model of mine gas safety evaluation resulted from organically fuzzy comprehensive evaluation method, AHP method and gray correlation method. The gas safety evaluation of five coal mine by using the integration model as an example for Heilongjiang Longmei Group Jixi Branch enterprise shows that the five mine are of better gas safety, in the＇ order of 1, 4, 5, 3, 2 in accordance with the merits. This study provides a new method for the valuation of coal mine gas safety.
