摘要：
The article proposes an integrated approach to safety evaluation in underground mining of rare, noble and nonferrous metals. The approach includes joint assessment of variable rock properties, zoning of mineral deposits and ranking of the integrity criterion of natural arch span. The authors validate geotechnical stability in sublevel stoping as a case-study of the Shokpak-Kamyshovoe deposit. The feasibility of mining of isolated and thin bodies without backfilling or with induced caving of enclosing rocks is determined.
