摘要
冀中能源峰峰集团新屯矿为老生产矿井,矿井通风方法为抽出式,通风方式为混合式通风,三进两回。目前矿井通风系统复杂,通风阻力大,给通风系统管理带来很大困扰。结合实际,运用事故树分析方法对矿井通风系统进行定性分析,确定了引起顶上事件的各个基本事件,计算得出30个最小割集和3个最小径集,找出了造成通风系统紊乱的可能原因及主要影响因素,并根据结果提出在以后通风系统管理方面的安全措施及应对策略,对未来通风系统的管理有着实际价值。
Xintun mine ventilation system is very complex,the ventilation resistance is big.Union example, Fault Tree Analysis（FTA） is used for qualitative analysis in management Of mine ventilation system, every basic events which cause the top event are confirmed. From constructing blasting fault tree,thirty minimal cut sets and three minimal pathway sets are atained. At the same time, the possible causes and the main infective factors of mine ventilation system are found. According to analysis results, the defects on mine ventilation system are pointed,and safety management measures,put forward, which has consult value to put safety mine ventilation system management into efect.
