FIELD: mining industry, possible use for liquidation of vertical courses of coal mines both at active and closed industries.
SUBSTANCE: in accordance to method for backfilling vertical courses of coal mines firstly strictly dosed mixture of burnt rocks and lime-rock binding agent is produced, then two technological operations are combined: transportation and mixing of received mixture, combination occurs in vibro-conveyers (horizontal and vertical). Filling is performed in layers with following spilling of water.
EFFECT: provision of safety of above-mine complex during whole protected period, provision of favorable ecological situation at adjacent territories (prevented forming of chasms in earth surface, forming of hydraulic connection between water formations, prevented exhaust of mine gases at day surface, etc) and utilization of industrial wastes (burnt rock).
