Claims8
A method of seismic prospecting wherein a detonating fuse-cord comprising an explosive core and an outer layer of elastomeric material formed with longitudinal external ribs is fed in a continuous manner through an advancing tubular conduit to lie in a position substantially parallel to the upper ground layer of a prospect area, the fuse-cord is detonated and the resulting seismic waves are recorded after reflection or refraction from subterranean rock layer interfaces, said longitudinal external ribs enabling said fuse-cord to pass through the advancing tubular conduit with less drag and greater abrasion resistance than a plain fuse-cord without the external ribs.
