On the stress state in the roof
Authors:
Abstract
The study of the stress state in roof pillars and the related issue of determining their safe dimensions are still relevant in the mining industry. As is known, the stability of a roof pillar is determined by the tensile stresses arising in it, the greatest value of which is reached at the contour of the working. The magnitude of these stresses depends on the thickness of the roof pillar, on the elastic properties of the roof rocks, on the depth of the working, and on other factors."
