Abstract
In deeper level mining in Tashtagol deposit, during extraction of ore reserves from safety pillar, the stresses and inelastic strain zones increase 2–4 times. In safety pillar in Sheregesh deposit, the tensile stress zones, where failure of undermined rocks intensifies, enlarge as mined-out stoping void grows. During mining in the Eastern and Northwestern sites of Tashtagol deposit, at the tunneling speed of 2.0–2.5 m/day and more, rock bumps of energy class 5–6 are recorded. In mining of Podruslovy and New Sheregesh sites, the decrease in the energy class of rock bumps is achieved at the tunneling rate of 0.4–0.6 m/day. The feasibility and sequence of safe extraction of ore reserves from safety pillars established under the Kondoma and Bolshaya Rechka rivers are justified. The backfill options in extraction of ore reserves from safety pillars in Tashtagol and Sheregesh deposits are discussed.
