	%X At the end of the 20th century it was actual the
development of transport corridors and the improvement of their
technical parameters. With this purpose, many countries and Georgia
among them manufacture to construct new highways, railways and
also reconstruction-modernization of the existing transport
infrastructure. It is necessary to explore the artificial structures
(bridges and tunnels) on the existing tracks as they are very old.
Conference report includes the peculiarities of reconstruction of
tunnels, because we think that this theme is important for the
modernization of the existing road infrastructure. We must remark
that the methods of determining mining pressure of tunnel
reconstructions are worked out according to the jobs of new tunnels
but it is necessary to foresee additional mining pressure which will be
formed during their reconstruction. In this report there are given the
methods of figuring the additional mining pressure while
reconstruction of tunnels, there was worked out the computer
program, it is determined that during reconstruction of tunnels the
additional mining pressure is 1/3rd of main mining pressure.
