Annotation:

The issue of the selection of a safe type of mine working support in conditions of increasing mine pressure and its manifestations in dynamic form, with the reduction of mining operations when developing rock-bump hazardous deposits at the EVRAZ ZSMK (West Siberian Metallurgical Plant) OJSC, has been considered.  
The results of studies and long-term practices identified that the physical and mechanical properties of rocks and the stability of rock and ore mass in the course of mining operations are the main factors affecting the choice of support have been analyzed.
The sequence of initial data preparation, including the fracturing assessment methodology and the state of marginal mass part based on the conditions of the use of various support types, depending on the mine working locations in relation to the direction of the main components of stress fields, is described.
The results of analysis and long-terms studies completed by the Research and Development Institute of Mining Geomechanics and Survey, Eastern Research and Development Mining Institute, Mining Business Institute of the Siberian Department of Russian Academy of Sciences, Kuzbass State Technical University, and the practices of using various support types that helped develop the procedure algorithm using digital technologies, the reasonable choice of support in given conditions and its implementation as a software product “EvrazrudaKrep” are provided. 
The software helps promptly address the problems of choosing a type of mine support and preparation of mine working support certificate to ensure the stability of the rock mass and safe operation of heading drivers in changing mining and geological & geodynamic conditions.
