目前,国內外许多矿山为提高凿岩效率,在巷道掘进中采用了台车。为了让人们了解各种台车概况,本文列出凿岩机、推进器和钻臂的主要设计特点,并介绍墨根矿山长期使用推进器的操作经验。在过去的十几年中,巷道掘进采用支架式凿岩。应用了23—30公斤重的高效率重型凿岩机后,使有效钻速提高了100％,可是为提高凿岩效率增加机重却使耗损在搬运、开孔和临
At present, many mines at home and abroad have adopted trolleys for tunneling in order to improve drilling efficiency. In order to provide an overview of the various trolleys, this paper presents the main design features of rock drills, thrusters and booms and describes the operational experience with long-term use of thrusters at the Morgan Mine. In the past ten years, tunneling using steerable rock drilling. The application of 23-30 kg heavy high-efficiency heavy-duty rock drill, the effective drilling rate increased by 100%, but in order to improve the efficiency of drilling to increase the weight but make the loss in handling, drilling and temporary
