建立了矿井提升机断绳事故故障树通过对某矿主井断绳坠箕斗事故的原因分析表明在提升机紧急制动情况下不可能引起断绳事故分析结果为第一处断绳原因在于钢丝绳质量问题而第二处断绳主要是由于松绳引起冲击冲击力大于钢丝绳理论破断力
The fault tree of broken hoist accident of mine hoist was established. The analysis of the cause of broken hoist and skip accident in mine main hoist indicated that the reason of broken rope accident could not be caused by the emergency braking of hoist was that Rope quality problems and the second is mainly due to broken rope rope impact impact force greater than the wire rope theory breaking force
