METHOD FOR COMPLEX DEVELOPMENT OF STRUCTURALLY-MORPHOLOGICALLY DIFFICULT DEPOSIT Russian patent published in 2014 - IPC E21C41/00 

FIELD: mining.

SUBSTANCE: according to the method, they perform serial tunnelling of polyfunctional deep adjacent trenches, which make it possible to combine opening of adjacent areas and blocks of the deposit, information geological prospecting and operating mining works - stripping and extraction ones, automated selective separation of good and temporarily off-grade elements from the massif in the form of a granular mineral mass and its separate loading into transport reservoirs. Flow delivery of the mineral mass to the day surface with the help of a portable rope-skip transporting technical system, moved in pipe-shaped guides with the minimum width of the trench, and in the open working space - with maximum width that excludes contact of the moving transport chain with planes of panels formed by boards of adjacent trenches.

EFFECT: increased efficiency of development of morphologically, structurally, parametrically, genetically, location-wise and substantially complex structural-morphological deposits of solid minerals of rock and semi-rock type.
