Substantiation and Development of Mineral-Saving Geotechnologies of Valuable Semiprecious Raw Materials Extraction with the Use of Drilling and Blasting Operations
In the article «spare» technologies of semiprecious mineral raw materials extraction on the example of Transbaikal deposits are described. The principles of ensuring the preservation of crystalline and ornamental semiprecious raw materials on the basis of reduction of the seismic action of blasting at the stage of stripping and mining of mining operations are justified. The theoretical substantiation of screen crack and safety distances of blast hole charges use to the productive zones of semiprecious crystalline raw materials in the process of clearing works is given
