煤矿主井提升机装煤系统断绳保护技术改造

摘要

For the problem that rope off on Main hoist coal loading system will cause coal stacked on the bottom of main and vice skip and machine jammed,proffer using magnetic proximity switch on the rope off protection of hoist coal loading system for technological transformation.Through technological innovation,and achieved good results.%针对主井提升机装煤系统发生断绳事故会造成主井主副箕斗下部堆煤而卡死的问题,提出利用磁性接近开关对提升机装煤系统断绳保护进行技术改造。通过技术改造,取得了良好的效果。
