Selection of mobile fasteners when mining thick sloping seams with narrow faces

Abstract
Both in the USSR and abroad coal seams of gentle dip with thickness more than 3,5-4,5 m are developed by inclined layers with caving, with laying or in some cases (France, England) with smooth lowering of the upper layers and the roof of the seam. These systems are characterized by relatively low technical and economic indicators due to the high cost and labor intensity of the construction of the foundation or preliminary support.
