A tubular fuse, which is supplied with an explosive gas, is formed so that as the explosive gas is detonated a turbulence will be created to aid in the propogation and continuance of the detonation. To achieve this turbulence, the inner circumferential surface of the tubular fuse is roughened at least along a portion of the length of the fuse. Alternatively, turbulence may be created by coating the inner circumferential surface of the fuse with a fine-grained powder.
