通过对钢材运输平车车体结构及车辆运行状况等的调研了解,对钢材运输平车进行制动装置改造,介绍了钢材运输平车现状,阐述了钢材运输平车制动装置改造内容,指出该改造方案满足客户和现行铁路货车相关标准的要求,降低了车辆改造成本,经单车试验及闸瓦压力试验,符合相关标准规定,为铁路货车类似车型车辆的改造设计与实施提供了参考.

Because of the rich fault and joint in the open-pit west stope slope in Heishan iron mine,large area landslip occurred,and it threatens the safety production.The in-site recorded and described and engineering drill measures were adopted,the properties of fault and joint in the open-pit west stope slope was obtained.The stability of the slope was analyzed,and the countermeasures were proposed.Some countermeasures have conducted,such as,the flood intercepting trench,the reserved broad stairs in 770 m level and shotcrete and rock bolt support strengthen in the broad stairs.It eliminates the threat of safety production with 770 m level upper slope to the lower slope.It grantees safety production in the deep open-pit mine.
