FIELD: mining, particularly to develop steep ore deposits in upward order.
SUBSTANCE: method involves sinking hauling entry of overlaying level, field incline, drive connecting hauling entry with chamber, sub level field entry, drive communicated with drill drift and ore drill drift; drilling well ring to upper overlaying chamber undermining mark; cutting ore; discharging and unloading cut ore; filling chamber goaf with pourable rock filler, wherein the rock filler is supplied directly from drives in chamber from hauling entry of overlaying level and rock filler is distributed over chamber area and compacted with the use of earth-moving machinery to create flat bottom.
EFFECT: decreased ore costs and volume of work in block, decreased ore losses due to total ore loading and block bottom cleaning with casing packer with remote control.
