Influence of the charge diameter on the granite crushing degree

Abstract

Quarries of Pervomayskiy and Aleksandrovskiy stone-crushing plants develop granites with a coefficient of strength on the scale of M. M. Protodyakonov 12-14 and volumetric weight 2,6-2,7 t/m3. The complex structure of granites and their poor explosiveness essentially influence on technical and economic indicators of drilling and blasting works ...
