Fomychov V. Scientific management basis of geomechanical systems with application of recursive methods for underground deposits mining

The thesis is devoted to development of scientific bases of geomehanichal system management using recursive methods for underground deposits mining on the foundation of mutual influence patterns of different types of optimal stress-strain state parameters of the system "massif - mount design and security" excavation workings in all phases of operation. It was formulated scientific and technical problem of improving excavation workings stability in mining of horizontal coal seams through sophisticated methods of calculation experiment operation in solving issues of managing of rock pressure influence distribution on support and security structures. On the basis of multiparameter nonlinear recursive model using high-precision simulation method was deve- loped generalized managing method of interacting system elements "massif - support and security structures" in various geological conditions. This method proved complex geomechanical elements that provide information and technical basis in solving problems of geomechanics in models of high level of geological conditions generalizations. By logical correction of managing system of multi-parametric recursive model was implemented design technology of excavation workings support elements for solution applied issues of underground mining of coal deposits. Based on the analysis of changes in the state of system "massif ? mount design and security" was implemented the method of rock pressure control, providing constant state of excavation workings considering long wall face advance horizontal shallow layers in laminated massif of soft rocks. The developed method of determining the optimum parameters of calculation models of coal-mining enterprises and technological regulation of support and excavation works secure with aim of their reuse.
