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. Once access has been gained into the coal seam, workings are developed by mining a series of roadways (or "headings"). These
