Abstract
The authors review the application range and parameters of internal dumping in open pit mining of brachysyncline-type coalfields. Specifics of the technology is described. The factors that govern the volume of internal dumping are identified. The possible ways of increasing the volume of internal dumping are shown. The methods and means for increasing the intake capacity of internal dumps are revealed. The ecological and economic advantages of internal dumping are discussed.
