Gas shows during construction of hydraulic tunnels
Conclusions 1. The given examples indicate that when driving tunnels in the Caucasus regions builder as a rule, come across in one form or another gas releases, mainly methane and carbon dioxide. 2. The presence of gas-containing or gas-conducting rocks along routes of tunnels has a considerable effect on construction time and cost and also requires the introduction of special safety measures and often the conversion of the working to a gas regime. 3. When driving tunnels it is necessary to carry out thorough engineering-geological documentation. Upon a change in the mining-geological conditions compared with the design conditions it is necessary to revise the issued forecasts on possible gas shows and accordingly to introduce corrections and methods of tunneling, supporting the workings, and checking the state of the underground atmosphere.
