Mining pressure control in hollow seams with hard-to-collapse roofs
Authors:
Abstract
One of the directions of improvement of technical and economic indicators of coal mining in the development of gentle seams is the wide introduction of the most progressive method of controlling the mining pressure - the complete collapse of the roof with perfect types of mechanized fasteners, complexes, as well as complete and individual fasteners. However, as shown by research and experience of a number of domestic and foreign mines, the development of seams, which have in the roof strong, difficult to collapse rocks, is very labor-intensive and far from safe (and under certain conditions, even inadmissible) process ...
