Abstract. Objective of the research is to study possibility to involve into quarrying operations those mineral resources, which are located in zone of possible funnel formation. Analysis of the current iron-ore market state shows that in order to improve competitiveness of domestic enterprises it is necessary to involve additional reserves of minerals, which were previous-ly lost during the underground mining operations. It is recommended to apply technology of safety mining of these areas by filling them with the crushed rocks taken from the surface of the quarry benches. Theoretical laws of the dry crushed rocks passing through the stowing wells are described. The proposed technological solutions show that it is possible to involve into quarrying oppera-tions additionally 30 millions of iron ore in conditions of the CGOK Company’s quarry.

Keywords: open pit, underground cavities, joint development.
