矿井提升机防坠装置缓冲器的改进

Improvement of buffer for fallproof device of mine hoist

探讨了用液压缓冲器代替摩擦式缓冲器的方法，经改进的缓冲器可增加矿井提升机防坠装置的安全性，使事故后的处理时间大大缩短。

The ways replacing frictional buffer with hydraulic buffer were discussed, the improved buffer can increase the safety of fallproof device of mine hoist and largely shorten the time to dispose the accident.
