FIELD: mining industry. ^ SUBSTANCE: backfill fibrosolution consists of concrete, argil, fibers and water, as fibers solution contains synthetic filaments with diameter 0,1-0,15 mm and length 10-20 mm in amount of 10-20 kg for 1m3 of argil-cement mixture, subjected to electrification with induction of static electric charge. ^ EFFECT: possible backfill of extensive fractured systems with active influx of water, increased hardness of backfill material, decreased material costs of reinforcement of fractured rocks, removal of water influxes in mines. ^ 2 ex |
