FIELD: mining.
SUBSTANCE: method involves central and flank preparatory mining operations; their fastening by roof bolting, control of formation pressure, stowing of the worked-out area, transportation of broken ore after preparatory mining operations using self-propelled equipment and implementation of ventilation, supply of stowing mixture, water drainage, loading and transportation of rock mass, as well as additional processes of mining practice are performed on one and the same preparatory horizon, which was passed along ore body and supported in natural massif. Peripheral part of workings is pre-formed by passing through rooms adjacent to development working, installation of metal fittings in them and filling by means of consolidating stowing; after that, development working is performed along the ore under protection of the already formed support in the form of stowing reinforced-concrete solid mass.
EFFECT: increasing the development efficiency.
