Schemes of mining and construction operations have been developed for inclined trenches on the open pit edge, where transport platforms and safety benches using the drilling and blasting method of rock mass preparation are located. The volume of mining operations is calculated taking into account the dislocation of a part of the open pit edge of the deep open pit mine for placement of loading points at the bottom of inclined workings. A new scheme of conducting mining operations implementing steeply inclined conve...

A regulation of the mining operations mode during a new phase of open pit mining deep lying minerals through implementation of temporary non-operating open pit edges on many deep open pit mines made it difficult to extract minerals. Innovative technologies of working zones development along steep open pit edges have been tested at the pre-design stage with comparison of the obtained mining schedules with the design schedules based on the analysis of methods of controlling mining operations mode and their existing ...
