METHOD FOR DEVELOPMENT OF COMPLEX-STRUCTURE DEPOSITS OF SOLID MINERAL DEPOSITS Russian patent published in 2020 - IPC E21C41/26 E21C47/00 B07B1/00 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for open development of complex structure fields. Method of development of complex-structure deposits of solid minerals involves development of a steeply inclined core by means of a milling unit consisting of a platform, as well as a boom made telescopically, and of a working element installed on a cantilever fixed on the boom. At the initial stage of the boom development by the turning hydraulic cylinder is installed at the required angle, loosening is performed from top to bottom, the rock mass from the lower platform is transported by the known method, and working member is lifted into initial upper position during movement of carriage with boom on platform or platform along ledge. Platform moves along the ledge to the next working position after several movements of the carriage with the boom on the platform along the guides, at the distance equal to the movement step for development of the next layer. Control of movement of working element with jib along trajectory of inclined core is performed by means of automatic system. Working element is installed on the cantilever fixed on the boom to ensure development of the steeply inclined windings blowing by means of the boom turn.

EFFECT: technical result consists in improvement of efficiency, increase in functionality and reliability, as well as expansion of process efficiency.
