矿井通风系统是一个复杂的系统,针对其评价中各指标的层次性和模糊性,从通风动力及设施可靠性,环境可靠性,安全监测系统可靠性,防灾救灾系统可靠性4个角度,划分出各层评价指标,确定各指标层的权重。建立矿井通风系统安全可靠性二级模糊综合评价模型,划分评价等级和模糊综合评价矩阵,对矿井通风系统安全可靠性进行了模糊综合评价,得出安全评价等级,使得安全评价结果更加科学性、准确性和可靠性。
Mine ventilation system is a complex system. According to the hierarchy and fuzziness of each indicator in the evaluation, from four aspects of ventilation dynamic and facility reliability, environmental reliability, reliability of safety monitoring system and reliability of disaster prevention and relief system, Divide each layer of evaluation index, determine the weight of each index layer. The second level fuzzy comprehensive evaluation model of safety and reliability of mine ventilation system is established. The evaluation grade and fuzzy comprehensive evaluation matrix are divided. The safety evaluation of mine ventilation system is carried out by fuzzy comprehensive evaluation. The grade of safety evaluation is obtained, which makes the result of safety evaluation more scientific. Accuracy and reliability.
