Abstract
Depletion of available mineral resources in the metallurgy industry, as well as the growing internal and external demand for the high-quality iron products necessitates development of new iron ore fields in Siberia. This article offers description of climate, geology and hydrology in the area of the Bakchar oolitic ironstone deposit in the Tomsk Region as a promising subsoil use object. The literature and engineering solutions on this matter are reviewed. The mining risks in the conditions of high environmental standards and market uncertainty are described. The basic requirements are formulated for the potential geotechnologies, and the conceptual framework is proposed for the environmentally sound and resource-saving mining with smart usage of natural and manmade resources in the iron ore production cycle.
