In open cast mining, after stripping the top soil away, the hard overburden needs to be drilled and blasted and then removed with a dragline, to expose the coal seam. The blasted material must then be correctly fragmented to ensure suitable conditions for the dragline in which to operate - namely, a soft digging environment.
A bucket-wheel excavator (BWE) is a heavy equipment machine used in surface mining.. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a ...
