Blinnikova Y. Developing of method to predict conditions for efficient undermining of buildings at coal deposits

The object is influence of earth surface deformation on undermined buildings. The purpose is development of method to predict conditions for efficient undermining of buildings. The methods are analysis of results of natural observations for undermined buildings and theoretical analysis of building's deformated state. The new approach lies in development deformation schemes of undermined buildings on base of structural deformations of wall exfoliation and in new estimated rates; there is developed procedure to determine standard allowable deformation rates for buildings taking into account their service conditions has been worked out; there is proposed a new universal characteristic for estimation technical state of buildings on base of their remaning deformation resource; there is developed a criterion of initial ground movements for undermined buildings. The results of thesis as formulas and tables there are used in designing of building undermining and there are implemented in coal branch standard and designs of building undermining. The field is coal industry.
