Influence of saltatory change of coal seam thickness, taking place during mining in the areas of dislocations on the tense-deformed state of face working space part of rock massif is considered. Estimation indicates a necessity of application of additional outburst preventing measures in plough faces, for example in the places where the callus of roof rock appears in plough faces.
