MINING STRUCTURE OF THE INCREASED SEISMIC RESISTANCE LAUNCHER UNIT Russian patent published in 2021 - IPC E02D29/00 E04H9/02 

FIELD: mining.

SUBSTANCE: invention relates to the field of fortification and can be used as a mine structure in areas of high seismic activity. Mine structure of a launcher with increased seismic resistance includes a mine shaft vertically buried in the ground, consisting of tubing and a bottom, a protective device, a shock-absorbing device, a transport-launch container and a compartment with equipment. The structure is supplemented with an external cylindrical barrel made of precast concrete components, a decorative and protective plate, a base plate and supporting point elements configured in the form of metal balls. The bottom and the base plate are installed relative to each other with a structural gap and metal cup-shaped recesses are made in them. Inside these recesses metal balls are located, which are suitable for their free movement in any direction of the horizontal plane. The shaft is installed coaxially inside the external cylindrical shaft with the formation of an annular cavity with a width not less than the radius of the bowl-shaped recess.

EFFECT: simplified design, reduced manufacturing labor intensity and increased operational reliability.
