🚧 The drill and blast method in surface mining is a sequential process used to break rock into manageable fragments. It begins with drilling a pattern of holes into the rock face, followed by loading the holes with explosive charges and stemming them with inert material to confine the blast energy. The holes are then detonated in a controlled sequence to fragment the rock for removal. After blasting, the broken material is excavated using loaders and haul trucks and transported for processing o

Mining Doc Mining Doc on Instagram: "What are the key considerations in designing a blasting sequence and delay timing? Blasting sequence is the planned order in which explosive charges in a blast are detonated, while delay timing is the specific interval of time between sequential detonations. Together, they are critical for achieving finer rock fragmentation, controlling rock displacement, and minimizing ground vibrations by allowing seismic waves from each explosion to interfere constructivel

The energy might be the same, but the engineering behind each blast is a completely different game. Tunnel blasting relies on ultra-precise millisecond delays to pull the rock backward and safely open the face, while large quarry blasts use wide-scale sequential firing to shatter and push thousands of tons of material in one controlled wave. This reel shows the real power needed to carve mountains, drive infrastructure, and fuel mining operations. And yes—the sound is 100% worth the replay. Most
