Horobchyshyn O. Development of scientific support for the process of management of stone blocks fracture in preparation for a recess.

The dissertation is devoted to the solution of actual scientific problems related to the analysis and assessment of the process of technological fracturing of rocks at blocks recessing, development of processing methods that could reduce the formation of fracturing technology .The thesis proposed a rapid diagnosis method of the specific fracturing of granite samples from different deposits by using MATLAB. The technique provides a quantitative assessment of specific defects and can be used during examinations of defective blocks and their products.On the basis of theoretical and experimental studies was established that the margin of the berm's angle is an area of high stress concentration, which contributes to the intensification of the process of additional microcracks, significantly reducing the strength of stone blocks . The algorithm for the simulation of stress intensity changes in the corner region, depending on the angle of the berm; the technique and software for the analyse of concentration zones formation of the critical stress, their patterns of spatial distribution which promotes the developing of separation technology of stone blocks from the array were created.
