Underground Hard Rock Mining

Using the latest technology can improve underground hard rock mining efficiency.

Underground Hard Rock MiningFundamentally, underground hard rock mining has changed very little over the last century or so. Shafts and tunnels are excavated and constructed to allow miners to reach an ore zone, the ore body is broken up using blasting or other methods, and the resulting material transported along tunnels and up shafts to the surface where it is crushed and processed.

It has even been said that if a miner from 100 years ago was taken to a typical underground hard rock mining operation of today, he would probably be impressed by the size, scope and speed of the operation, but would recognize and understand most of the core activities. The machinery may be more advanced, but basic methods have changed very little in many mines.

However, there are an increasing number of mines that would probably convince the miner of old that he had ended up inside a mine on another planet, were he to suddenly find himself brought forward in time. The reason for this is the widespread adoption and intelligent use of the latest digital technology by certain progressive underground hard rock mining companies. Technological solutions and systems are used to facilitate better planning and development of mines, as well as intensive real-time monitoring of equipment and manpower; manage and substantially increase production output and simultaneously decrease unit production costs; and enhance mine safety via monitoring and early warning systems.

Throughout the Europe, Middle East and Africa (EMEA) region – and the world – underground hard rock mining operators are exploring the use of technology as a means to improve productivity and ensure the safety of mine personnel and equipment

Controlling costs and remaining competitive and financially viable are constant challenges for operators of underground hard rock mines. Making intensive use of new technology is the logical starting point for making every aspect of a mine’s daily operations more efficient, and therefore more cost effective.
