FIELD: mining industry.
SUBSTANCE: method includes separation of a level on hexahedral sections of upwardly elongated shape and is prepared by driving of field backup drift. From the drift shafts are driven below each section, from which along mineral resource ascending shafts are drilled, meant for drilling from them by horizontal or slanting wells and extracting sections resources. Outlet of extracted rock mass is performed through ends of shafts. After outlet of rock mass from all sections ceiling beam is brought down and let out also through ends of shafts.
EFFECT: lower laboriousness, lower costs, higher efficiency, higher personnel safety.
