FIELD: process engineering.
SUBSTANCE: invention relates to mining and may be used in operation of underground storages made in permafrost rock to bury drilling wastes. Proposed method comprises hydraulic transfer of drilling wastes from drilling site via pipeline to and into underground reservoir. In rock drilling, drilling slime is separated from drilling solution, treated to produce pulp to be carried via pipeline by waste drilling solution or service waster. Immediately before filling underground reservoir by drilling wastes, drilling slime is separated from conveying fluid to feed it back to drilling site. Filling with drilling wastes is made pumping drilling slime therein. In longer outages of conveying system, pulp is withdrawn from pipeline by evacuating pipeline system or blowing it by compressed air.
EFFECT: efficient burial, minimum amount of drilling solution used.
