On the issue of determining the sizes of inter-chamber pillars

Abstract

In the article “Determination of the sizes of interchamber pillars,” placed in the XVII-XVIII volume of “Notes of the Leningrad Order of Lenin Mining Institute,” an expression is given that determines the dimensions of the interchamber pillar through the adhesion force of a given rock C and its angle of internal friction. Determining the adhesion force through the tensile strength of the rock allows us to approach the issue of determining the sizes of inter-chamber pillars with great objectivity.
