Possible solution for extraction of gas-bearing coal seams by highly productive mining complexes

Article preview

The problem of extraction of flat-lying gas-bearing seams at high depths is considered. Technological scheme of ventilation of long-wall faces with highly productive mining complexes is proposed. Economical effect for conditions of the coal mine MUK-96 is calculated.

Substantiation of rational mining parameters for iv potash horizon of the starobin potash deposit

Article preview

Methods of substantiation of a rational mining technology for the new potash horizon are presented in the paper. Progressive technological mining schemes for potash mining company «Belaruskaliy» are reviewed, as well as the geological conditions of the IV potash horizon. Basic aspects of the geomechanical substantiation of parameters of technological mining schemes for conditions of the IV potash horizon in the presence of influence of the overlying horizons are also presented. Results of modeling of the stress-and-state strain of the rock strata with production horizons are described.
