Maximising coal recovery in challenging geologies represents a significant efficiency opportunity for most coal mining operations to increase the value of their resource. As the easy coal is mined out, mine operators need to become more skillful at mining thin, steep, deep and undulating seams productively and without sacrificing coal quality.

In most underground mining methods, deep vertical tunnels called shafts are drilled into the ground, along with a set of horizontal tunnels called drifts from the shaft bottom to access the ore. Then, longwall and continuous miners break up the ore deposit, which is transported back to the surface by conveyors.

Shafts are a core component of many underground mining operations—an activity that sits squarely in the critical path of the project manager's schedule. Traditionally, it has always been one of the most challenging of operations, and for that reason it remains the preserve of specialist contractors like RUC Mining.

mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
