CONTOUR MINING STRUCTURE FOR EXTRACTION AND TRANSPORTATION OF PREPARED ORE MASSIF FROM PIT BOTTOM Russian patent published in 2024 - IPC E21C47/00 E21C41/26 

FIELD: construction; mining.

SUBSTANCE: invention relates to mining and construction industry, and specifically to complex production handling equipment. Lifting structure for transportation of broken rock mass in a pit contains two interacting moving units, which are located relative to each other on separately prepared sections of oppositely located pit walls. Mobility of said units is performed in longitudinal direction in relation to sides within reach of their equipment of installed working zone of mine working. Each of said moving units consists of operating frame platform equipped with means of movement, which forms a support base, structurally providing for the presence of handling equipment controlled from the operator station, which working elements are made with possibility of movement to the extraction area by means of separate transportation lines, which form common air suspended connections uniting movable units for intake and movement of broken rock mass to the place of its unloading. Each of the separately prepared sections is an equipped building structure consisting of a central bearing platform in the form of an elongated podium located along the width of the deposit planned for development with a transportation surface for a movable installation and a retaining component and from reinforced slopes adjacent to the ends of said podium, which are interfaced with inclined transport ramps, transport ramps form a relatively flat roadway for mining trucks, adjacent to the longitudinal side of the podium closest to the centre of the mine working.

EFFECT: increased completeness of extraction of rock mass of deposit and provision of high safety of operations.
