Abstract
The problem of the increase of the volume of rock mass for single blast is relevant through all the history of drilling and blasting. Change from factory to in-situ produced explosives, increase in consume of industrial explosives and the necessity of mechanization of blasting operation, problems with the quality of the blasted rock mass have become more actual. These problems are especially actual with mechanized charging of flooded wells by emulsion explosive. These problems are primarily caused by human factor: firstly, the emulsion explosive is multicomponent; secondly, explosives are produced in situ; thirdly, a shortage of qualified personnel. To solve the problem, a methodology for determining the quality of the charge of a bulk emulsion explosive in watered wells is provided in the article. The necessity of measuring of the detonation velocity of borehole charges and addition of this measuring to technical conditions for drilling and blasting operations is substantiated in the article.
