The biggest feature of the mine electric locomotive is that it can tract other transportation equipment, mining ores and construction personnel during work. It is one of the important equipment indispensable in mine or tunnel production. At the same time, the electric locomotives used in coal,metal mine or tunnel operations are driven by DC or AC series excitation motor. This type of method not only has a fast and stable effect in mining or tunnel operations, but also can well adapt to the more difficult operations of underground mining because of its relatively soft mechanical properties and a very simple structure.
