Savenko A. Development and substantiation of combined method mechanized support shift in longwalls

Thesis is devoted to problems of effectivization of the complex-mechanized process engineering of management working on deep levels in which one the relevant scientifically applied problem on the basis of new comprehension alternating accelerations of a convergence of adjacent rocks is decided, as measure of variation of the intense-deformed state of a rock, for installation of an expansion of areas of intensive effect of processing steps of a hewing and travel units to the powered support in high-efficiency breakage faces on a bottom. For the first time the empirical-formula dependence of rate of evolution of strains in a rock mass from depth of management activities and an advance rate of a breakage face is established, and also peak figures of rate and acceleration of a convergence of adjacent rocks in area of processing steps of a hewing and units powered supports in a wall that has allowed to develop new effective combined method of powered supports units shift are updated.
