Justification of data quantitative assessment based on geomechanical processes taking place in coal-rock massif around the coal cutting face
The parameters of coal massif and roof rock stability, of shock and outburst danger, of permeability of underworked massif are suggested which allow at the stage of project making to make a complex evaluation of coal-rock massif geomechanical condition around the coal cutting face in order to provide safe conditions for coal cutting
