Abstract
The scheme of vault hypothesis formation and the calculation method of loading on KMP-A3 arch support are presented. The presence of the outcrop contour in the ore massif of the Yakovlevskoye deposit is taken into account. Loads on the support in loose, medium-density and dense ores were determined.
