摘要
针对金属矿山通风系统的特点,从安全的角度出发,选取金属矿山通风系统中的13个指标构成金属矿山通风系统安全评价指标体系。采用模糊数学的方法,构造了各个指标的隶属函数,将矿山通风系统中存在模糊性评价语,转化为数值的形式。将矿山通风系统的实测数据代入可以得到各个指标的隶属度。给出了各个指标的权重值的计算方法。构造模糊综合评价模型,对其结果进行整理得出百分制评价分值,并将评价得分分级给出各级的评价结论。判断矿井通风系统的安全程度,为管理者提供决策依据。
According to the features of metal mine ventilation system, this paper chooses 13 indexes composing the safety evaluation index system of metal mine ventilation system. Membership functions are constructed by fuzzy mathematics, using this fuzzy words used to describe the safety state of the mine ventilation system can be transform into numerical type. Membership degree of index could be got when inserting measured date of mine ventilation in membership function. The weight of evaluating indexes could be got from the formula this paper given. And then using the comprehensive evaluation model this paper given we could get the evaluation result. The safety degree of mine ventilation system was graded by the assessment result. This provides decision-making basis for managers.
