Abstract
The Article presents the method for the determination of a minimum permissible thickness of rock interstrata, with which it is permissible to apply the steel-polymer roof bolts upon undermining of a coal seam. The method is based on the results of investigations of behavior of roof layers above the productive working with using the deep datum marks.
