The reason for the large losses and clogging of the ore mass is the lack of operational quality control in the production and transportation of the blasted rock mass, as well as the technical means of operational control of the depth and orientation of the operational wells in the ore mass. In addition, when drilling wells, their deviation from the design direction, an average of 10-15% of the depth, resulting in a contour reflection of substandard rock mass, as well as remaining unrecovered part of the ore. As a result, mining companies carry quantitative and qualitative losses of ores, clogging of the blasted rock mass occurs.5481 Product Description popup.authors Моркун В.С.
