SYSTEM FOR POSITIONING A TUNNELING COMPLEX IN SPACE Russian patent published in 2020 - IPC E21D9/02 E21C35/08 

FIELD: mining.

SUBSTANCE: invention relates to mining industry, in specific case to devices for determination of coordinates and spatial position of tunneling complexes of small diameters, consisting of several modules, during construction of rectilinear and curvilinear tunnels, including in construction of rectilinear and curvilinear tunnels by method of squeezing down of tunnel timbering. Positioning system of the tunneling complex in space includes a laser transceiver fixed in the starting shaft, one or more intermediate laser transceivers, installed at distance from each other within the range of providing direct visibility in the erected part of the tunnel, and receiving phototarget mounted on the tunneling complex, interconnected by a wire communication interface through interface modules, wherein the laser transceiver and the intermediate laser transceivers are identical and comprise a platform with a laser emitter and a laser range finder. At that, platform is made with possibility of rotation around horizontal and vertical axes due to electric drives with feedback, and the receiving phototarget is installed in each module of the tunneling complex and is configured to determine the spatial position of the tunneling complex modules.

EFFECT: technical result consists in providing the possibility of determining coordinates and spatial position of tunneling complexes of a modular structure during construction of both rectilinear and curvilinear tunnels, including squeezing method.
