融合模糊控制理论的煤矿粉尘防护设施量化评价

Fuzzy control theory based quantitative evaluation of dust protection facilities in coal mine

为改进对煤矿粉尘防护设施降尘效果的评价,建立一种融合模糊控制理论的量化评价方法。首先,针对粉尘防护设施建立多层次评价指标体系,并以逻辑斯蒂方程为主体,构建评价因子的隶属度函数;其次,基于模糊控制理论,研究构造评价论域模糊器和解模糊器,并利用层次分析法(AHP)确定评价因子权重,建立模糊控制量化评价(FCQE)数学模型;最后在某矿掘进工作面实施量化评价。结果表明:FCQE法改进了AHP法获取评价论域的方式,无需依赖专家的评判,但在评价因子权重中又融入专家知识,这样直接采集数据后即可快速实现量化评价。对比该矿粉尘检测数据,评价结果与实际情况比较吻合。

In order to improve the evaluation of the dust removal effect of coal mine dust protection facilities,a quantitative evaluation method with fuzzy control theory was developed.Firstly,a multi-level assessment index system was established for the dust protection facilities,and membership functions of the evaluation factors were constructed with Logistic equation as the main body.Secondly,based on the fuzzy control theory,a fuzzifier and a defuzzifier of evaluation universe were studied and established,and the weights of the evaluation factors were determined by using AHP.A mathematical model of FCQE was built.Finally,a quantitative evaluation was carried out at a certain mine heading face.The results show that the FCQE method improves the way to obtain the evaluation universe in AHP,which means there is no longer the need to rely on the experts＇ judgment（the expert knowledge is integrated into the weight of the evaluation factors）,so that the quantitative evaluation can be achieved quickly after collecting the data directly,and that the evaluation results conform to the actual situation.
