Sotskov V. Justification of location and fastening parameters of the overworking roadways while extraction works conducting in the mines of Western Donbass.

Defended established patterns of extraction works influence on the stress strain state of massif in the vicinity of overworking roadway depending on the depth of the works, face position, parameters of the structure and mechanical properties of the host rocks. Regression equation for calculation of the minimum sufficient distance between the soil and the coal seam contour generation were obtained, as well as the algorithm of choice of rational parameters of the fastening system. These results were obtained on the dataset of multiple calculations of stress strain state of massif in the vicinity of overworking roadway. Spatial geomechanical models were used taking into account the geological structure and properties of Western Donbass rock massif, the effect of weakening factors as well as real workings support. All calculations are made in elastic-plastic formulation. On the basis of the experiments identified shortcomings of the fastening system that forms the basis for the roadway of rational methods for determining the rational parameters of overworking roadways support. This research allowed to develop recommendation system for reliable and low-cost support of overworking roadways in Western Donbass mines.
