Abstract

The practice of anchoring roofs with anchors is based mainly on an empirical approach - the trial and error method. The theory of anchoring is more descriptive than mathematical. Due to the complexity of geological, mining and technical conditions of underground workings, it is very difficult to describe mathematically the destruction of the roof of the workings reinforced with anchors. Nevertheless, even qualitative identification of the factors causing the destruction of the edge parts of the coal seam and, as a consequence, the roof collapse, can provide justification for the development of the anchoring passport and safety improvement.
