The structure of the miner's car: Announcements state that miner's cars are capable of being used with ore gates (or loaders) for loading materials. China developed the bucket conveyor train in the 1970s, consisting of bucket cars, a lift platform, and a series of miner's cars. Once the bucket cars are filled with material, they are lifted by the platform and moved along the miner's car sides, individually transferring the material into each miner's car, thus increasing loading speed and achieving continuous miner's car loading. The bucket loading train has a simple structure, a small turning radius, and can be modified using existing standard miner's cars. The miner's car wheels have flanges, and there is a certain gap between the flanges and the rails. The tread surface where the wheel contacts the rail is shaped conically to keep the wheelset centered as it runs along the track, reducing mechanical wear and lowering running resistance. China's standard narrow-gauge railway track gauges include 600mm, 762mm, and 900mm. The basic structural components of the miner's car are the car body, frame, wheelset, and connectors.

Side-discharge mining trucks are composed of movable side doors, pull rods, unloading curved tracks, and tilting bins. During operation, the unloading doors on one or both sides are opened using the unloading curved tracks at the unloading station. Common capacities range from 2.2 to 5.5 cubic meters. Single curved track side-discharge mining trucks: one or both sides of the bin can be opened, and the truck tilts by using the unloading curved track installed at the ore discharge point, with the pull rod opening the side door for unloading.
