矿井采掘工作面通风效果的综合评价

运用模糊综合评价法对矿井采掘工作面进行了通风效果的评价,先确定了影响工作面通风效果的指标,并逐一构造了其隶属函数,然后采用层次分析法定出评价指标的相对权重,最后对计算模糊评判的算法进行了分析,以此来确定采掘工作面通风效果的评价等级。以东滩煤矿部分采掘工作面的环境状况为例进行了评价,据实际考察评价结果反映,通过该评价方法得到的结果与现场完全一致。

Ventilation Effect Evaluation of Working Face in Coal Mine

Fuzzy comprehensive evaluation method was used to evaluate the ventilation effect of working face in coal mine. First, the index system was determined and their membership functions were set up. Then, the analytic hierarchy process (AHP) was applied to decide the important degree of the evaluation indexes, and the algorithm to calculate fuzzy evaluation was analyzed, by which the evaluation grade of ventilation effect was decided. Taking the ventilation system of working face in Dongtan coal mine as an evaluating example by this method, the result shows that it is completely in line with the real condition.
