Head Chistyakov Ye.P., Registration Date 27-01-2004 Organization State scientific-research mining institute popup.description2 The parameters of motion of adjacent strata are investigated at mining steeply dipping potent reservoirs by a floor-chamber system with hardening and hydraulic stowing at the scheme of improvement of reservoirs "chamber - pillar". The actual values of displacement are lower computational in 1,2 times. The parameters of zones of roof falls and cracks are counted at not-to-laying of chambers on 0,1... 0,5 their volumes.
