Methodology of calculation of loads on artificial pillars
Abstract
Chamber systems of development with solidifying backfill are becoming more and more widespread. This causes the need for further development of calculation methods for determining the basic parameters of the systems and strength properties of the backfill. The purpose of such calculations is a reasonable choice of the width of inter-chamber pillars, chamber spans, width of a panel or block, dimensions of inter-block (panel! pillars, determination of the required strength of artificial pillars. The results of calculations, of course, will be different depending on the order of development of sections (blocks), chambers within one block, the structure and properties of the filling massif and other conditions.
