THE EXPLORATION OF THE OLD COPPER MINES OF XVII-XIX CENTURIES IN TATARSTAN.
Copper mining is the least studied kind of the old man-made cavity. After finishing of their exploitation the mines passed into the natural stage of development and were considerably transformed by different processes. Caved phenomena in the mines are reflected on the surface in the kind of craters, gaps, etc. It is rather dangerous for building, transport and people. Speleologists study configurations of galleries in mines and predict caved phenomena.
