COMPLEX OF EQUIPMENT FOR REPAIR OF MINE WORKINGS Russian patent published in 1997 - IPC

FIELD: reclaiming of cross-section of development mine workings. SUBSTANCE: complex has powered walking support from two units, continuous miner for excavation of rocks of heaved floors, scraper conveyor, lining placer, and car with support members. Scraper conveyor has horizontal section square to longitudinal axis of the complex and inclined section parallel to this axis. Continuous miner is mounted on conveyor front horizontal section for advancing over it under its own power. Mounted on two-sided frame are scraper and hydraulic tables. Frame is connected with powered support which may have units different in design. The main unit is made of hydraulic props, rigid base and roofing, and located over longitudinal axis of the complex, and additional unit may consist of arcs or frames interconnected by longitudinal skids and girders for directed advance. Arcs consist of interconnected by hinged short capping and two side members with anchor hydraulic props for limit turning of side parts. Mechanism of longitudinal advance may have four hydraulic jacks, two of which are located at upper capping of support main unit and mounted on guide girders secured to cappings of arcs, while the other two, are located at lower ends of anchor hydraulic props of rear arch of additional support unit and mounted on extension plates of turning mechanisms of side parts of this and connected with turning parts of additional support unit. Hydraulic tables may have guides for rail track and conveyor and capable of transverse motion over frame with change of distance between their longitudinal axes and height of location. Lining placer may have extensible hydraulic grip and mechanism for turning of telescopic part and may be mounted on rear end of the main support unit for limited turning. EFFECT: higher efficiency.
