[0002] With the reduction of shallow ore quantity, more and more mines adopt the way of underground mining. With the development of downhole on-site mixed loading truck technology, underground on-site mixed loading explosive trucks are widely used in underground mining. The underground on-site mixed loading truck usually has an articulated chassis or a common mining chassis, and the speed of the chassis is 30 - 40 km / h, which is relatively slow. Installing a matrix storage tank on the same chassis increases the vehicle's center of gravity. During daily work, the mixed loading truck needs to go to the emulsion matrix preparation station (or storage station) to load the emulsion matrix, and then go down the well for charging and blasting operations. Due to the low speed of the mixed loading truck chassis, and the large slope and long slope length of the ramp transportation in underground mines, there are problems such as high fuel cost, environmental pollution; long preparation time and low work efficiency; and there are also potential safety hazards.
