| Abstract: | Features of the condition of underground mines are presented and basic principles for developing ore mining technology are
formulated. It is noted that the main direction for improving mining operations in nonferrous metal deposits is development
of mining systems with stowing by solidifying mixtures with waste utilization from mining and metallurgical industries based
on the complexes of self-propelled machinery. In order to extract lowvaluable ores under conditions of great depths new variants
of breast chamber mining systems, and sublevel caving systems with leaving rock intercalations in the bowels are considered.
For ferrous metallurgy mines of the region the expediency is demonstrated for radical reconstruction of technology with development
of mining system by sublevel caving with end ore drawing and comprehensive use of self-propelled equipment.
