Locomotive Transportation: Main Mode of Mine Transportation in China

The huge production requirements of the mine require the use of mine electric locomotives to transport ore, waste rock, materials, equipment and personnel, and so on. As a result, mine electric locomotives and mining vehicles make up the mining trains. Mine locomotives are the power of train transportation. The mine track transportation system is a locomotive traction tractor running on the track, which is the main way of horizontal long-distance transportation. Former domestic underground mines mainly use locomotive rail transportation, a small number of conditional underground mining by motor transport, there are a few mines using belt conveyor transport, pipeline transportation and rope transportation. Locomotive transportation is the main mode of mine transportation in China. Major equipment track, tub, traction equipment and auxiliary machinery and equipment, often with rake mining equipment, loading and unloading equipment, belt conveyor or trackless transport equipment and other components of the effective transport system. 

With the transport system will have a track, the track is laid by the bottom of the roadway or open-air ground on the two rails and their accessories. Gauge is divided into standard gauge and narrow gauge, the standard gauge is 1435mm, narrow gauge is divided into 600mm, 762mm, 900mm three. 

Rail transport can fully adapt to the changes in distance and roadway bending, both for horizontal roadway can also be used for inclined roadway, and the inclination is almost unlimited. However, there are shortcomings of rail transport, rail transport capacity and transport distance. Other conditions are the same, the transport capacity with the increase of transport distance decreased; work organization is complex, need more auxiliary operations. 

The main equipment of the mine track transport is the transport winch (or hoist), mining vehicles and mining motor vehicles. In the mine rail transportation, in addition to the above-mentioned main transport equipment, in order to carry out the operation of tram grouping, transceiver, positioning, loading and unloading, must be installed in the system loading station, inclined shaft up and down the receiving and dispatching yard Field, and with the corresponding station equipment. Commonly used station equipment mainly dumper, stop vehicles, carts and scheduling winch and so on.

The task of mine electric locomotives transportation is to transport the ore (waste rock) from the stope, stope or chute to the underground storage, downhole (or middle) depot through the transport roadway or directly The main task of open-pit mine locomotives transportation is to transport ore from the stope to the ore dressing yard. The waste rock transporting will be transported to the ore-dressing ground, and the waste materials will be transported to the mine. To the dump.
