Abstract
The resource-saving technology is proposed for mining watered lignite deposits in the Kansk-Achinsk basin without drying of productive strata. The expediency of accumulation of all water inflows in mined-out area of the open-pit mine for the subsequent use in the closed production cycle is substantiated. Effectiveness of hydromechanization in selective stripping of incompetent overburden rocks with solid inclusions is determined. Parameters of a hydraulic fill placed in the mined-out area of the open pit are presented.
