These pit mines continue to be enlarged until there is no more ore to mine or the overburden becomes too heavy.This mine is a hillside open pit. The rock formation and slope of the open pit have the similar strike and dip, and the similar dipping angle. The striking of the slope and the rock formation are the NE direction, dipping SW with the dip angle of 35–40: The typical geology section is shown in Fig. 2.
