For mining medium-hard materials on the surface "Continuous Surface Miners" have been employed for some years The latest generation surface miner extends the performance of this type of machine to the point where the same cost efficiencies can now be achieved in medium-hard materials as has been achieved in softer materials by machines
Open pit mining results in two waste streams: waste rock which contains no economic quantity of minerals but which must be removed to gain access to the orebody and tailings which are the result of a mineral separation process in the concentrator or processing plant The mining rate includes the mining of both waste and ore
LONGWALL MINING Overview In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block with one rib of this new roadway forming the longwall face
