Abstract
The article is aimed at developing a technology for mining valuable ores with maximum preservation of natural contacts of ore zones with empty rocks and reduction of mixing of the rock mass during explosive loosening. A new method for working out local areas of mineralization in strong rocks using explosive loosening of rocks in the conditions of natural "clamping" by a natural array with decelerations between successive bursts of borehole charges above 300 MS is proposed. This allows you to achieve a minimum displacement of the exploded rock mass in both horizontal and vertical directions without any additional costs.
