矿井提升较多地采用了落地多绳摩擦提升机,介绍了落地多绳摩擦提升中的绳带绳换绳方法,并采用事故树分析法分析换绳过程中存在的风险,找出导致风险存在的基本事件,以预防事故的发生。
The multi-rope friction hoisting machine with floor landing is adopted more and more for mine hoisting. The method of replacing ropes with ropes in multi-rope frictional lifting is introduced. The accident tree analysis method is used to analyze the risk existing in the rope changing process, Basic events to prevent accidents from happening.
