矿井通风安全系统稳定性评价方法与应用

Stability Evaluation Method and Application of Mine Ventilation Safety System

依据山西某地矿区实地工况,考虑到矿区风井数量多、风量比较大、瓦斯浓度高以及阻力大等特征,以层次分析法为基础,设计了一种针对矿井通风系统的评分标准,确立通风系统稳定性能的最高评分指标且确定稳定性层次分析图,建立各指标的加权系数。经过实验可知:该地区通风系统整体性能评分结果是“优良”,处于良好等级。

Based on the on-site working conditions of a certain mining area in Shanxi,and considering the characteristics of a large number of air shafts,large air volume,high gas concentration,and high resistance in the mining area,a rating standard for the mine ventilation system was designed based on the Analytic Hierarchy Process(AHP).The highest rating index for the stability of the ventilation system was established,and the Analytic Hierarchy Process(AHP)chart for stability was determined,with weighting coefficients for each index established.Through experiments,it can be concluded that the overall performance rating of the ventilation system in this area is"excellent"and is in a good level.
