基于组合赋权的煤矿作业人员行为安全状态界定及评估研究

Definition and evaluation of behavior safety state of coal mine workers based on combination weighting

为减少煤矿行业安全生产事故的发生,融合安全行为及不安全行为定义、行为安全理论、MMEM系统理论,提出煤矿作业人员行为安全状态的界定标准。根据行为影响因素,建立煤矿作业人员行为安全状态评价指标体系,包括4个一级指标和21个二级指标,利用改进层次分析法、熵权法和差异系数法确定主、客观权重及组合权重,选用可拓综合评价法构建评价模型,并选取某煤矿进行实例验证。研究表明:针对煤矿行业,D-E-I模式具有普适性;实证评价等级为Ⅳ级,即“比较安全”,评价结果符合实际,模型科学性与实用性较强。

In order to reduce the occurrence of safety production accidents in coal mine industry, this paper combined the definition of safety behavior and unsafe behavior, behavior safety theory and MMEM system theory to put forward the standard definition of safety state of coal mine workers’ behavior.According to the behavior influencing factors, this study established the coal mine workers behavior safety state evaluation index system, including 4 first-level indicators 21 secondary indexes.The Improved-AHP method, Entropy Weight method and variance coefficient method were adopted to determine the subjective and objective weights and weight combination.Taking one mine as example for analysis, this paper chose extension comprehensive evaluation method to construct the evaluation model. Results show that: For the coal mine industry, the defined-evaluation-improvement(D-E-I)model is universal.The empirical evaluation level is Ⅳ or “relatively safe”.The evaluation results are in line with reality, and the model is scientific and practical.
