METHOD FOR CONSTRUCTION OF RISE TUNNEL AT ANGLE UP TO 30 DEG AND TRANSPORTATION VEHICLE FOR ITS REALIZATION

摘要

FIELD: mining construction. SUBSTANCE: rock is withdrawn vertically and transferred under gravity by closed vessel 6 rotating round its longitudinal axis. Vessel 6 is tube with ports in its lower part and axial rolling-contact bearing on lower end. Lower part of tube 6 with ports is connected with tight chute 17. Chute 17 is connected with its other end to hopper and to ventilation plant. Vehicles 12 and 13 for men and materials are installed on tube 6 by means of wheels 20. Wheels 20 are secured for turning their rotation planes relative to longitudinal axis of tube 6. Tube 6 is installed on rollers 7. Vehicles 12 and 13 are moved and polluted air withdrawn simultaneously with removal of rocks by rotating vessel 6. EFFECT: higher efficiency. 2 cl, 2 dwg
