我矿副井提升为双层罐笼提升,罐笼载重8 t,副井下放长料采用大罐吊罐底的方法,上井口南侧装料.下井口南侧出料,吊罐底法下放长料,即长料固定在罐笼底部,装罐下放最长不超过5 m,这种下放长料法的下放速度不能很高,仅为全速的1/4,由于长料在罐笼外部安全性特差,下放长度过短不能满足生产需要.而且每次下放长料时,副井口下井口要将安全门及其上面的跑道梁和1根套架梁去掉,工作量大,井口作业时间长,增加了下放长料的不安全性。1 改造方案(1)上井口安全门横梁抬高500 mm,在套架顶部
The auxiliary shaft of mine was upgraded to be double-layer cage lifting with a cage load of 8 t. The auxiliary shaft extended the long-stemmed material with the method of large tank hanging bottom tank, loading the material on the south side of the wellhead. That is, the long material is fixed at the bottom of the cage, and the maximum length of the tank can not exceed 5 m. The decentralized long material method can not be lowered very fast, only 1/4 of the full speed. Due to the long material safety outside the cage Poor, decentralized length is too short can not meet the production needs.And each time the release of long material, the auxiliary wellhead wellhead to the safety gate and the runway above the beam and a beam to remove the beam, heavy workload, wellhead operating time is long, increasing Unsafe 1 transformation program (1) the upper wellhead safety door beam elevation 500 mm, at the top of the set
