Head Chistyakov Yevgeni Petrovich, Registration Date 09-09-2009 Organization State enterprise "Scientific-research mining institute" popup.description2 Here is made study of geology-survey documentation and calculations of surface displacement parameters for two variants of deposits mining by systems with backfilling of the worked-out area: 1-t variant - deposits with thickness not less than 12 m are worked-off by room system, less than 12 m - by slicing; 2-d variant - all deposits are worked-off by slicing system. According to calculations results there are built basins of shearing and graphs of subsidencies, inclinations, curvature and horizontal deformations. Measures for guarding surface objects in accordance with their guard category are developed. Product Description popup.authors Зеленська Т.С. Куліш С.А. popup.nrat_date 2020-04-02 Close
