ABSTRACT

Increasing the competitiveness of coal mining in Ukraine is directly associated with a decrease in the prime cost of final products by main cost objects, from which the cost of maintenance of mine workings is significant. A modern analysis of the production activity of mines in Ukraine indicates that repair work in mining operations is by 60% related to the elimination of the consequences of bottom rocks heaving, where about 42 thousand of underground workers are employed. The problem of bottom rocks heaving is the most acute in the Western Donbas, where a thin coal-bearing massif is prone to plastic flow, and the process of bottom rocks heaving is already intensively developing at low depths. The main criteria for assessing a particular technique accuracy is an adequate reflection of mine observations results of the rock pressure manifestations, structural and technological parameters for maintaining mine working and an appropriate application of the mechanics of deformable solids.
