Chapter 16 Mining and Minerals Flashcards QuizletBauxite Land Reclamation Rehabilitation
Subsurface mining where a rotating shear on the mining machine shaves from blocks or panels of mineral in a back and forth motion similar to that of a meat slicer and dumps the broken coal onto a conveyor belt that extends across the longwall As the mining machine advances the roof behind it Reclamation The bauxite and alumina companies rehabilitate mined out land by following a four step method The mined out area is first reshaped and the top soil that was first stripped off to prepare for mining is replaced The area is then restored by planting the reclaimed area with pasture grasses primarily to prevent erosion
