The Mining Process. 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). Once access has been ...

The coal delivered from the mine that reports to the coal preparation plant is called run-of-mine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground engaging tools. ROM coal can have a large ...
