Essay

With the account of existent mathematical analogy between the change of mas-sif and heat conductivity by a solution the Fur'e method of differential equalization for a two layer rock mass "alluviums - carbon", new analytical correlations which characterize the stressed-deformed condition of any point of rock mass and earthly surface on any stage of coal mining are obtained. Speed of moving of wall face and reological properties of rocks are taken into account. Included the differential equa-tion of hardness parameters of rock mass are certain MBE by the developed calcula-tion algorithm. In the algorithm the correlations of task of S. Crouch are used for semi-peate, due to which maximum terms on the external contour of the probed area of rock mass (earthly surface) are executed automatically and discretisation only in-ternal contours. By the obtained analytical correlations for the geological conditions of mines in Western Donbass certain indexes of deformations of earthly surface in incomplete and complete extraction and the stressed-deformed condition of rocks are analyzed on the coal seam horizon. Formulas are obtained for the calculation of maximal indexes of deformation of earthly surface.
