FIELD: mining.
SUBSTANCE: proposed method comprises first layer roadway development at 6 degrees to horizon and stowing with stowing mix. After solidification of top layer stowage massif, lower layer road headings and their stowage are performed. In compliance with this invention, after first top layer roadway development, pipeline is laid in roadway soil via which bottom layer cuts are filled.
EFFECT: higher safety.
