Current achievements in blasted rock fragmentation quality assessment: Review

The article gives a review of the foreign and domestic practices in application in assessment of blasted rock fragmentation quality. The grain size composition of blasted rocks serves a criterion of the drilling and blasting quality, for this reason, it is important that the data on blasted rock fragmentation are accurate and reflect the real-life picture. To this effect, it is required to have a system of the blasted rock fragmentation quality assessment such that is capable to provide a correct picture of rock fragmentation by blasting. This research aims to compare the foreign and Russian achievements in the sphere of blasted rock fragmentation quality assessment, to reveal the global trends in development of program products for the fragmentation quality assessment, as well as to examine the feasibility of adopting the foreign experience in Russia. The relevance of this research is governed by the aggravated problems connected with supply of the Russian mining companies with foreign software products because of cessation of business activity of some foreign companies in Russia, complicated licensing and servicing of software products and limited supplies. On this basis, it has been concluded on the necessity to develop proprietary program products in the sphere of the blasted rock fragmentation quality assessment toward self-sufficiency and independence from foreign analogs. The article offers a set of recommendation for software designers, companies and engineers in mining.
