Combined Roof-Bolting Systems of Mine Workings wireless access point security It now faces a life-sappingThe basic principles of geomechanical processes occurring in mine workings during the extraction of minerals are discussed in this monograph. Particular attention is paid to the support system, specifically to the various roof bolt and frame support designs, and also to the modern means providing resource saving conditions for ensuring mine workings sustainability. The basic principles of the computing experiment performance at the modelling of
