CHAPTER 11: MINE WASTE DUMP

These waste rock dumps are heterogeneous in terms of grain size and structure. The fragmentation of rock in a dump is a product of number of mechanical processes, like drilling, blasting, ripping, etc. Consequently, dump rock may range in size from clay particles to boulders (e.g. less than 0.1 mm to greater than 1 m in diameter).
