Abstract

The regularites of the change in the sand grain composition obtained as a result of tuff crushing in four deposits in the Lori Marz have been investigated. Bazed on the test results, the link between the bolts' hole diameters and the sand quantity percentage passed through the holes is revealed. The experimental results are presented in tables, graphs and in a mathematical form.
