什么是喷砂工艺？一阵风吹过，十年老锈一扫而光！

Surface blasting is used to fracture and displace competent rock that cannot be excavated mechanically. By carefully designed drill patterns, explosive selection, and timing, blasting controls fragmentation, reduces dig forces on equipment, improves loading efficiency, and maintains wall stability. 💥💣 When done correctly, it optimises production while managing vibration, flyrock, and ground control for safe mining operations. 💪🏻 | FIFO Australia
