摘　　要：针对矿井粉尘浓度过高导致粉尘爆炸以及尘肺病频发的问题,为了有效改善矿井粉尘管理措施从而降低高浓度粉尘危害,从人、机、环境、管理四个方面利用预先危险性分析的方法找到了矿井粉尘灾害的危险源,制定了矿井粉尘危害安全评价指标体系,运用事故树分析找到导致粉尘危害事故发生的基本事件组合。在此基础上,分析计算各基本事件的概率重要度。最后,针对各个基本事件组合从预防粉尘爆炸和尘肺病两个方面提出改善矿井粉尘防治措施的方式方法,以提高矿井作业的安全性。Aiming at the problem of high dust concentration in mines leading to dust explosions and frequent pneumoconiosis,in order to effectively improve mine dust management measures and reduce the harm of high concentration dust,the hazard sources of mine dust disasters are identified from four aspects:human,machine,environment,and management using pre hazard analysis method.A safety evaluation index system for mine dust hazards is developed,and fault tree analysis is used to identify the basic event combinations that caused dust hazard accidents.On this basis,analyze and calculate the probability importance of each basic event.Finally,based on various basic event combinations,ways and methods to improve mine dust prevention and control measures are proposed from two perspectives of preventing dust explosions and pneumoconiosis,in order to enhance the safety of mine operations.
