  • Planning Process | Introduction | underground COAL

    Planning Process. Once all the exploration information is available, planning can begin in earnest, though often it begins while the exploration process is still in progress. The start of the planning process is the elimination of any parts of the lease which cannot be worked at all or cannot be readily mined for whatever reason. This, together with some knowledge of coal quality will allow an ...
