The mining battery motor is mainly used in the mines with coal (rock) and gas (biogas, methane) and the main air roadway with full air pressure ventilation, as well as the main return air duct and air inlet and return duct in the mining area of the gas mine, the excavated rock roadway but the underground roadway without stringing, the traction mine car group, transportation equipment and personnel.zmwm11
The electric locomotive is a kind of traction equipment for rail vehicle transportation. The power is to use the traction motor to drive the wheels to rotate, and use the friction between the wheels and the rail surface to make the locomotive run on the track. In this mode of operation, its traction is not only limited by the power of the traction motor (or internal combustion engine), but also by the friction between the wheel and the rail surface. There are restrictions on the slope that locomotive transportation can travel on. The slope of the transportation track is generally 3‰, and the local slope cannot exceed 30‰. According to the structure, there are overhead electric locomotives and battery electric locomotives.
The working principle of the battery-type electric locomotive is similar to that of the overhead-type electric locomotive. The DC power provided by the battery drives the motor to run through components such as flameproof plugs, controllers, and resistance boxes, thereby pulling the train to run.
Battery-type electric locomotives are powered by batteries. Battery charging generally runs in the underground motor garage. After the battery pack on the electric locomotive is used to a certain extent, remove it and replace it with a charged one. Therefore, each electric locomotive must be equipped with 2-3 sets of battery packs.
Advantages: no risk of spark explosion, suitable for use in mines with gas; no need to wire, flexible use, very suitable for transportation systems with small output and irregular roadways and roadway excavation transportation.
Disadvantages: charging equipment is required; initial investment is large; electricity consumption efficiency is low, and transportation costs are high.
