Статистическая оценка параметра периодичности модели зональной дезинтеграции горных пород

In work the problem of zonal disintegration of rocks around deep underground developments is considered. The small review of scientific works in the field is provided, the main results and the conclusions about their convergence with natural data and laboratory experiments are reflected, the used methods and approaches are described. In the work the parameter of frequency of function of deficiency which is the solution of a task on distribution of the field of tension around development of round section, in the conditions of an incompressibility and hydrostatic character of a loading on infinity is investigated. To be carried out a statistical assessment of a significance of earlier received analytical dependence, the linear look, parameter of frequency of function of deficiency on position of the middle of the feed zone of destruction. The alternate is constructed statistically the reasonable model of a non-linear look describing this dependence. The comparative analysis with earlier obtained results and the experimental datas is carried out. Statistical significance of non-linear dependence of parameter of frequency of function of deficiency, from position of the middle of the feed zone of destruction, its convergence with natural data and advantage before dependence of the linear look is shown.
