Essay

In thesis there are the considered influence of reaction of subsystem is changing in space and influence to border state stability of strengthening rocks border balance and formation of spatial diagram of loadings on support from weight of rock in crack zone, heterogeneity of geometrical, mechanical and force parameters of a subsystems "strengthening rocks-support" to its strain-stressed state. The revealed laws in a complex with the developed criteria of optimization of models of interoperability of geomechanical system "massif-strengthening rocks-support" are seen. These laws forms a scientific basis for improvement of constructive-technological diagrams of strengthening border massif with anchors and hardening mixtures. The algorithm of optimization of modes of interoperability of system "massif-strengthening rocks-support" is created that takes into account spatial character of fluctuations of its geometrical, mechanical and force parameters. The method of the forecast of display of rock pressure and a method of calculation of strainstressed conditions of a subsystems "strengthening rocks-support" are developed.
