Essay

Thesis is devoted to the questions of reliable and economical fastening of mine production sites on the basis of providing the correspondence between the intense state of fastening and safety factor and deformation ability of its units and bearing elements.In the work the motivation of the mechanism of forming the active load on the fastening in conditions of high and middle metamorphism is given; the regularities of intense state of fastening, which include the dimensions of area of active load, the angle of lying of containing rocks, and parameters of reactive resistance are determined; the particularities of deformation processes in the roof of preparation site when the front of defogging works is moving and their influence on the preparation site. This allowed motivating and designing the new constructions and technological methods for controlling of intense state of fastening, which provide the increasing of stability of mine production sites, decreasing of material and labour expenses for theirstrehgthening.
