MetadataShow full item record
The work purpose is to develop effective technologies of extraction of semiprecious stones with taking into account energy failures of mineral resources. The main methods of research conducting are methods of statistical processing, analysis and synthesis of data and economic-and-mathematical analysis. Classification of deposits of Ukraine that containing semiprecious stones raw materials is developed as a result. Classification of mining methods by criterion of energy consumption during mining is substantiated. The cost of extraction of semiprecious stones considering energy costs of deposits mining is defined.
