Abstract
The influence of block structure of the rock mass on the stability of sides of mountaintop quarries is estimated. The results of laboratory studies of deformation and destruction along the contacts of blocks, depending on the composition of filler between the blocks, are presented. It is found that shear resistance along the contacts of blocks depends on the composition and internal friction angle of the filler.
