针对煤矿电气火灾频发问题,考虑到煤矿电气火灾危险源呈现模糊性强且复杂多变等特点,基于层次分析模型建立煤矿电气火灾评价指标体系,选取G1法分配评价指标权重。计算结果表明,导致煤矿电气火灾发生的诸多指标中人员因素的权重为0.583 3,其中人员因素中疏忽管理和员工违章作业两子指标权重较大,分别为0.277 0、0.173 1;电气设备异常的权重为0.416 7,其中电气设备异常中导线短路和电气设备过负荷的权重较大,均为0.096 0。研究结果为强化煤矿电气火灾的安全管理提供科学参考。 Aiming at the frequent electric fire in coal mine, taking into consideration the characteristics such as ambiguity and complexity in the hazard of coal mine electric fire, this paper established the evaluation index system of coal mine electric fire based on AHP, and selected the weight of evaluation index by G1 method. The calculation results show that the weight of the personnel factors in many indicators that lead to electrical fire in coal mines is 0.583 3, among which the negligence of personnel factors and the heavier weight of two sub-indicators of employees’ illegal operations are 0.277 0 and 0.173 1, respectively; The weight is 0.416 7, in which the short circuit of the electrical equipment and the overload of the electrical equipment have a greater weight, both of which are 0.096 0. The results provide a scientific reference for strengthening the safety management of coal mine electrical fires.
