Abstract
The experience of drilling and blasting operations at limestone quarries in Finland is described. The comparative characterization of drilling and blasting parameters, adopted for similar conditions in Russia and Finland, is carried out. The problems inherent in explosive mining of construction materials in Russian quarries are defined. The directions for improving the parameters of drilling and blasting operations are outlined, which will improve the quality of blasting preparation.
