东部井工煤矿安全因素重要程度分析及控制

Analysis and control of important factors of safety in coal mine

将影响煤矿安全的因素进行汇总,并把不同方面的影响因素归为不同的一级因素,运用层次分析法(AHP)计算这些一级因素各自在总目标中所占的权重,同时需要进行一致性检验,通过一致性检验则可以继续计算,若未通过一致性检验则需将判断矩阵进行调整,直到满足一致性要求。再将各一级因素细化分为若干个二级因素,用AHP方法计算各二级因素在其一级因素中所占的权重(也需进行一致性检验,要求同上),并根据已计算好的一级因素的权重,确定各二级因素在总目标中的相对重要程度,在面对实际问题时,可根据其重要程度依次采取对应的控制方法。分析结果表明:AHP方法可以准确分析出井工煤矿安全影响因素的相对重要程度,为该行业的安全管理提供了有效的参考依据。

The factors affecting the safety of the coal mine are summarized, and the influencing factors of different aspects are put into different levels of primary factors, analytic hierarchy process（AHP） is applied to calculate the weights of these factors. At the same time, the consistency check is required, and the consistency check can be used to continue the calculation. If the consistency check is not passed, the judgment matrix should be adjusted until the consistency requirement is met. Then the first level factors are divided into several secondary factors. The weights of all secondary factors in their primary factors are calculated by AHP method. According to the weight of the calculated primary factors, the relative importance of all secondary factors is determined in the total goal. In face of practical problems, corresponding control methods should be adopted according to their importance. The analysis results show that the AHP method can accurately analyze the relative importance of the safety factors of the well coal mine, and provide an effective reference for the safety management of the industry.
