Bubnova Y. Interrelation of deformations of preparatory developments working contour of with parameters displacement of rock mass on Western Donbass mines

Interrelations of parameters of stability of developments working and geomechanical displacement processes of a rock mass in zones of influence of breakage works is devoted. The offered model of interrelation displacement of a ground and displacement of developments working contours in zones of breakage face influence has allowed to establish horizontal displacements and deformation in a displacement mould, size of a seam shrinkage at management of a roof complete caving, horizontal and vertical displacements of developments workings contours, zone of influence of breakage faces on a state of developments workings, duration of active deformations of contours of developments workings. On the basis of these scientific postulates the developed methodology of account of displacement of developments workings contours and choice a direction of conducting breakage works rather strike of a seam. The developed model of interrelation between parameters of rock mass displacement and deformations of developmentsworking located in it, is confirmed by results of tool supervision on mines OAU " Pavlogradugol".
