        <p>Пласты угля, подверженные расщеплению, имеются почти во всех уголь­ных бассейнах, в том числе и Донецком. Характер расщепления и причины, вызвавшие его, изучали многие исследователи. Г.Ф. Крашенинников свел мор­фологические типы выклинивания мощных угольных пластов к следующим ос­новным случаям: 1) пласт, постепенно утоняясь, выклинивается; 2) расщеп­ление пучком; 3) расщепление с верхним пластом; 4) расщепление с нижним пластом. ...</p>

        <p>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. ...</p>
