Abstract
The support control system «MARCO» has programs for the estimation of a geomechanical situation around the face by continuous measurements of pressure in the legs of support. The analysis of the face convergence allows to predict the possibility of a rock burst. The seam’s reaction on the shearer or plough influence may be the dangerous main roof collapse into the mine-out space of longwall.
