Coal seam splitting
Abstract
The splitting of coal seams is an extremely characteristic phenomenon and is noted by numerous researchers for all coal basins and deposits. Already about 100 years ago, the phenomenon of splitting coal seams found a correct explanation in the works of C. Lyaille. For the initial position in explaining this phenomenon he took the following well-known principle: not the sea level rises, and the earth falls, and, conversely, not the sea level falls, and the earth rises. In other words, C. Leyel associated the splitting of coal seams with oscillatory movements of the Earth's crust of a differentiated kind. This point of view was later universally recognized. The splitting of coal seams is currently explained by the manifestation of differentiated movements of separate parts of the Earth's crust, distinguishing between plastic deflections and deflections as a result of clastic sinking and rising.
