The development of internal detonation experiments is presented. A formula is obtained, which is used to compute the arriving time of the shock wave in the tunnel due to explosions from high explosive charges. This formula is adopted to treat detonations that occur outside, inside, and at the portal of a straight tunnel of constant cross-section, and to compute airblast velocity in tunnel.
