坑道掘进中，装岩运输是一项繁重的工作，近几年来，装运方面逐步使用DK-1A型装岩机、电瓶机车和内燃机车，减轻了劳动强度，改善了作业条件，提高了装运效率，促进了坑探事业向前发展。而目前装运工作仍占作业循环时间的46％左右（运距约800米，两辆机车往返牵引梭车或矿车），所以抓紧装运设备改进定型配套工作，是提高装运效率、保证作业循环正常进行的重要关键，是实现坑道机械化作业的一项迫切任务。
Tunneling, loading rock transport is a heavy work, in recent years, the shipment gradually using the DK-1A rock loader, battery locomotives and diesel locomotives, reducing labor intensity, improve the working conditions and improve the shipping efficiency , Promoting the pit exploration business to move forward. At present, shipping still accounts for about 46% of the operating cycle time (about 800 meters away from the locomotive and shuttle trailers or coaches for two locomotives). Therefore, improving the shipping facilities to improve the shipping efficiency and ensure a normal operating cycle An important key to carry out is an urgent task of mechanized tunneling.
