METHOD OF OPENCAST MINING OF DEPOSIT OF MINERAL RESOURCES

摘要

The invention relates to mining and can be used in mining open way. The purpose of the invention - reduction of the volume of stripping operations by increasing the angle of the working board by its high working off ledges while reducing the work platform parameters. The method includes oburivanie invocation and ledges of rocks and the refinement of their stope, motor reversal at the bottom, forming a protective shaft on the working platform along the edge of the step at the border with the transport band. Simultaneously form an additional protective shaft on the newly formed shoulder slope, the volume fulfills stope set based on the reception on the platform blasted rock height of not more than 1.5 excavator digging height. 2 yl. ate with
