Abstract
Coal seams subject to cleavage, there are almost in all coal basins, including Donetsk. The nature of cleavage and the causes that caused it, studied by many researchers. G.F. Krasheninnikov reduced the morphological types of wedging thick coal seams to the following main cases: 1) seam, gradually thinning, wedges out; 2) cleavage bundle; 3) cleavage with the upper seam; 4) cleavage with the lower seam. ...
