The actual mining occurs at this step It is done in a narrow strip in an elongated form First the primary strip is mined for coal After it is extracted thoroughly the second strip is created by removing filth rock and waste from the top This debris is dumped on top of the first and used strip The process repeated till the last strip is reached...
