Selection of mobile suport when mining thick gently dipping seams with narrow face
Authors:
Abstract
Both in the USSR and abroad coal seams of gentle dip with a thickness more than 3,5-4,5 m are developed by inclined layers with caving, with stowing 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 stowing or preliminary support.
