Abstract
Cost reduction on stowing operations promotes efficiency of mining companies producing ore with goaf-stowing mining methods.
The article considers methods of cost reduction on stowing mixtures by adding either lignosulfonate as a plastisizer or soil stabilising additives such as ConcreCem (СС) and RoadCem (RC) or industrial wastes.
The stowing technology used at the mines of the transpolar branch of the Norils Nikel Mining and Metallurgical Company is an object of the study.
The laboratory and pilot results obtained at the mines of the transpolar branch are to be substantially verified.
