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...

This paper reviews a developed technology of mining steeply dipping mineral occurrences by steeply inclined sublayers, taking into account spatial position of sublayers relative to ore shoot. Parameters of phase and steeply inclined sublayers, till reaching final open pit depth, have been justified during studies. An order of steeply inclined layers formation on frontal open pit edges is determined depending on location of mineral resources on footwall and hanging wall. A new method of reactivation of a non-operat...
