Abstract:
A strip mining technique wherein an active mining area is continuously moved across a mining ground. In one form of the invention, overburden is removed from a leading end of the active mining area and conveyed by a conveyor system located on a highwall of the mining area to a following end of that mining area. The conveyed overburden is dumped adjacent the active mining area following end to form a spoil bank which is landscaped and reclaimed. Another form of the invention includes a conveyor system located on the main bench.
