The results of the aero- and gas-dynamics processes numerical researches for the sublevel caving mining system with mechanized roof support in conditions of «Kiselevskaya» coal mine are given in the article. It is shown, that reliable and effective panel ventilation is provided with the technological scheme with three entries at the each sublevel. The parameters of the technological scheme are determined.
The security issues of the deep mining of Prokopevsk-Kisilevsky deposit the Kuzbass are considered. The analysis of the existing technologies and systems development are executed. The recommendations to improvement of the technical and economic parameters, reducing accidents and injuries of the working off inventories powerful coal steeply inclined seams and steep coal seams were given.
