Underground Mining Methods — New Pacific

Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

How is gold mined? - Gold-Traders (UK) Ltd

Hard rock mining is the process of using open pit or underground mining tunnels to retrieve the gold from the rock. This method of gold mining is responsible for recovering most of the worlds gold supply. Byproduct mining is related to hard rock mining in that open pit or underground mining tunnels are used.

10-06-2015  The process of underground mining is considerably constrained by the geometry and geology of the mine. The various mining operations are normally performed in series at each working face. The delay of a single operation will lead to a domino effect, thus delay the starting time for the next process and the completion time of the entire process.

The Mining Process Introduction underground

Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from surface section for these terms).
