There are many operating equipment in the Side Dumping Mine Car. The advantage of the single-side curved track Side Dumping Mine Car is that it has a larger volume than the dump type mine car and fixed mine car, and it is automatically and smoothly unloaded. Small, generally only 5.2 meters long, the unloading inclination angle can still reach 55 degrees, effectively saving the development space of the well and reducing the size of the chamber. The unloading distance is short, and the digging volume of coal bunkers and depots is only one-third of that of other mine cars. Since the unloading curve is symmetrical, the two-way unloading of Side Dumping Mine Car can be realized.
