Essay

Geomechanical regularities change of boundary stressed states of complex-structure rock massif, which lies in the roofing at working sloping coal seams with the help of solid system of mining development, are stated in thesis. Research on the process of rock roofing's falling of coal seam on models with equivalent materials is done. On the basis of natural, laboratory and analytical research a three-stage model of roofing rock collapse of coal seams falling is proposed, which lets forecast main parameters of the process of rock massif destruction at drive's moving for concrete mining and geological conditions. Computer modeling of the roofing falling process of complex-structure roofing in drives allowed to watch changes of stressed deformed state for hard-to-fall roofing of sloping coal seam on the basis of method of boundary elements. On the basis of stated regularities of forecast and formula obtained for magnitudes of general and stable falling, nomogram is developed.
