METHOD AND SYSTEM FOR VERTICAL MINE TUNNEL CONSTRUCTION Russian patent published in 2006 - IPC E21D3/00 

FIELD: mining industry, particularly to erect vertical mine tunnels.

SUBSTANCE: method involves cutting rock at face; loading the cut rock and conveying thereof; mounting forcing-through plant connected to pump station and provided with support member, hydraulic jacks and pressing member; installing lining components in mounting chamber; forcing tunnel shield body and lining components. The tunnel shield body is forced simultaneously with forcing lining members upwards for height equal to lining member width with the use of hydraulic jacks provided in forcing-through plant. The hydraulic jacks are brought into action by executive tunnel shield tool movement relative tunnel shield body. The executive tool is permanently pressed to the face. The pressing member of the forcing-through plant consists of composite parts. Lining components are mounted in the composite forcing-through plant by lowering and lifting each component of the pressing member in turns. Vertical tunnel construction system comprises tunnel shield with executive tool of rotor type, ground transshipping mechanism, forcing-through plant with support member, hydraulic jacks and with pressing member to apply action on lining to be constructed. The system also includes ground distribution means and pumping station with control panel. The pumping station is connected to hydraulic jacks of the forcing-through plant. The system also has support member of the tunnel shield and hydraulic jack of executive tunnel shield tool. The support member is installed between the tunnel shield and the forcing-through plant. Hydraulic jack of the executive tool may cooperate with that of forcing-through plant. Ground transshipping mechanism is made as ground channel with hopper secured to the support tunnel shield member. Pressing member of forcing-through plant is composed of several parts, which may be serially displaced relative the lining.

EFFECT: provision of vertical shield movement and tubing support forcing in upward direction.
