Under discussion is the equipment for open pit mining of scarce coal reserves. Methods of overburden dumping are systematized. A new dumping method is offered; it allows reducing land withdrawal by means of utilizing adjacent open pit. The author presents relations for area of internal dumping, considering coefficient of dumping in the adjacent open pit and the volume of the adjacent open pit. The feasibility of overburden placement in mined-out pits is analyzed.
