In order to improve work efficiency and speed up the development of production, when mining, Mining Cart are used as the main transportation means of the mine, which can be used to transport coal, ore, waste rock and other materials. It can be divided into 5 categories in structural form:
(1) Fixed minecart: The carriage and the frame are fixedly connected, and the minecart must be turned and unloaded with a dumper. Its basic composition is a box, a frame, a bumper, a coupling and a walking mechanism. The frame is a metal structure that can withstand traction, braking force, collision forces between mine cars, and rail impact buffers. The shock absorbers are installed at both ends of the frame to reduce the impact between the two vehicles. The coupler is a component that connects the locomotive and the mine car. The bolt chain and the slewing chain are commonly used. The large-scale mine car uses an automatic coupler with a buffer function. The running mechanism is two wheel pairs consisting of 4 wheels and 2 axles. When the total amount of minecarts and materials exceeds 20 tons, the number of wheel pairs should generally be increased. For mining carts with more than two wheel pairs, in order to facilitate the turning of the two wheel pairs into a cart with a turntable through a curve, this cart is called a bogie.
(2) Dump-type minecart: sometimes also called side-turn minecart and mine bucket. The characteristics of the dump-type mine car are that the overall structure is simple, sturdy and durable, and easy to use. As long as the stopper is opened by human power, the material can be easily unloaded. Compared with the fixed minecart, this dump bucket is undoubtedly more flexible and convenient to use.
(3) Single-side curved rail side-loading minecart: The cart of this type of minecart can be opened on one or both sides. The minecart is tilted by the unloading curved rail installed on the unloading point, and the sidebar is opened for unloading by the drawbar.
(4) Bottom (side) dump truck: One or both sides of the cart can be opened, the cart can be tilted by the dump track installed on the dump site, and the lever opens the side door to unload (side dump) or the cart. The bottom plate is unloaded backward or side by gravity (bottom unloading). This form of mining cart is similar to the single-sided curved rail dump truck mentioned above.
(5) Shuttle type Mining Cart: The bottom of this type of mining cart is equipped with conveying parts like a conveyor belt. When loading coal, the front part is loaded first, and then this conveyor is used to transfer the coal to the back, until it is full. This type of mining cart is not called a shuttle-type mining cart in the shape of a shuttle, but because the workload of this winch is larger than the above-mentioned several mining carts, and it is named because of its shuttle-like shuttle transportation.
