Shepel O. Improvement of technology of working of reserves of the ore contacting to lying wall of steeply dipping deposits.

The thesis is devoted a solution of a problem of improvement quantitative and quality indicators of an ore mining at the expense of an intrusion of advanced caving systems of ore and adjacent strata. Definition of an indicator of size of explosive displacement of broken ore from an immobile zone of a lying side of a deposit in an active zone of release is one of the major solutions who defines efficiency of improvement of quantity indicators of an ore mining. It is developed and proved technological schemes of variants of advanced technologies of an underground extraction of steeply dipping ore deposits which allow to improve qualitative and quantity indicators of extraction of ore, and also to lower the cost price of its extraction at the expense of a decrease of specific expenses preparatory and access developments and expenses of explosive substances at breaking.
