Although underground mining is a less environmentallydestructive means of gaining access to an ore deposit, it is often more costly and entails greater safety risks than strip mining, including openpit mining. While most largescale mining projects involve openpit mining, many large underground mines are in operation around the world. 1.1.3
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, mainly those minerals containing metals  such as ore containing gold, copper, zinc, nickel and lead, but also involves using the same techniques for excavating ores of gems such as diamonds.
Underground mining is a distinct segment of the mining sector, with coal and other minerals being extracted from depth for processing. Being underground demands high safety considerations from strata control, and the maintenance of underground road networks is undertaken in confined spaces.
Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.
Underground mining. The Underground Mining platform provides specialist engineering, construction and operational services in the underground environment to the global mining and metals sector...
The mining industry is not without its risks, so workers need to be aware of mining safety tips that might save their life. Although there are industries with higher injury rates, the injuries incurred in mining are far more likely to be severe than those incurred by workers employed in private industry as a whole.
ZongXian Zhang, in Rock Fracture and Blasting, 2016. 19.11 Safety, environment, and vibration control 19.11.1 Safety. Working safety in underground mining is related to various factors such as blast operation, rock conditions, and mining methods. Here we do not discuss the accidents such as fires, traffic casualties, ventilation, water, electricity problems, and so on.
Induced Seismicity: Mines located in seismically active regions, such as the Andean region also known to be one of the wealthiest metallic mining zones in the world are particularly at risk. Especially dangerous in underground mining areas, mineinduced seismicity also causes slope instability in surface mining.
