Information × Registration Number 0211U008724, 0110U002387 , R & D reports Title Geomechanical provision of reserves mining in the level 301. . .330 m of Yuzhno-Belozerski deposit. Study of regularity rules for sresses distribution at polarization-optical models and estimate of stability of stoping blocks constructive elements worked-off by room systems with hardening backfill of mined-out area. popup.stage_title Head Chistyakov Yevgeni Petrovich, Registration Date 13-09-2011 Organization State enterprise "Scientific-research mining institute" popup.description2 There is performed mathematical analysis of data of hydrogeological and sound-ranging observations and also surveying measurements on the base of which the state of stoping rooms and protective pillar is estimated as stable. Here is modelled working-off rooms of 2/1s level 605-740 m and 1/1s level 715-840 m, made calculation of stresses and coefficients of their concentrations, recommendations on increasing rooms stability are developed.
