METHOD OF VERTICAL MINE BACKFILLING |
摘要 |
FIELD: mining. ^ SUBSTANCE: method includes layer filling of a mine with a backfilling material. The backfilling layer in the form of a cylindrical concrete block is previously made on the surface in an autoclave chamber. Concrete blocks are made with a cylindrical groove, at the same time the upper and lower surfaces are arranged as truncated. Installation of cylindrical concrete blocks in the shaft is carried out onto a hydraulic insulation putty. A gap between mine walls and blocks is solidified with a shrinkage-free water-resistant hardening concrete mix. ^ EFFECT: development of a water-resistant and shrinkage-free backfilling massif in a vertical mine to the moment of its backfilling completion. ^ 2 cl, 3 dwg |
