of mineral ore, then the proposed mining project could generate more than one billion metric tons of overburden and waste rock. These high-volume wastes, sometimes containing significant levels of toxic substances, are usually deposited on-site, either in piles on the surface or as backfill in open pits, or within underground mines.
Whether you need to excavate, transport or process ore, rock or overburden more efficiently, our comprehensive range of cutting-edge surface and underground mining equipment is designed to increase your productivity and boost your bottom line.

Documenting these areas of known underground mining and making that information available to those involved in community and business development was the objective of our project. The surface subsidence effect of underground mine caving incidents typically results in sinkhole depressions, pools, ponds or small lakes.
We are looking to develop an underground mine complex, using block-caving mining techniques to extract the ore and transport it to the surface to the concentrator. Block-caving, while technically challenging, is one of the safest and most cost-effective methods of mining ore .

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.
