Original Title: From Perforation, Blasting to Dumping, Understanding the Six Processes of Open-pit Mining in One Article! The mining process of open-pit mine is relatively simple, mainly including drilling, blasting,  equipment for deep-hole blasting mainly includes down-the-hole drill and roller drill. It can be used to drill ages of multi-row millisecond blasting: The one-time blasting quantity is large, the blasting times and the blasting avoidance time are reduced, and the utilization rate of the stope equipment is improved; The broken quality of ore and rock is improved, Mining Drilling Equipment , and the boulder rate is reduced by 40 to 50%  slag heap, and each row of boreholes, including the first row, can increase the charge and be fully crust of millisecls are piled up, which refers to the place where mining wastes are discharged in a centralized manner. According to the stacking sequence, the dump can be divided into single-bench dump,DHD Drill bit, covering multi-bench dump and slope-pressing multi-bench dump. The dump is mainly divided into road transport dump, railway transport dump, belt transport dump and hydraulic transport dump according to the dumping process.
