METHOD AND DEVICE FOR TRANSPORTING UNDERGROUND A MIX OF WATER WITH DISPERSED BACKFILLING MATERIAL,ESPECIALLY OF FLY ASH DUCT

摘要

1. The invention concerns a method of transport to underground of mine mixture of water and reduced filling material particularly smoke-box dust, the mixture is used for filling underground headings, characterised in that from surface of mine is transported to level, on which is located filled heading a mixture of lesser thickness, used for long-distance transport, then on this level mixture is thickened by removing from it part of water and this thickened mixture is transported to heading and used for filling cavity created by exploitation of rock.2. Device for thickening of mixture of water and reduced filling material, particularly smoke-box dust, characterised in that it has a closed container (1) connected to supply pipeline (2) supplying mixture of water and reduced filling material particularly smoke-box dust from surface of mine to container (1), and supplying pipeline (2) is equipped with valve (3) and to disposal pipeline (4) disposing on the side of bottom (6) of container (1) thickened mixture to heading being filled, and pipeline (4) is equipped with valve (5), also it has inside of container (1) floating suction rose (7) connected via lead (8) to water receiver.IMAGE
