摘要：
Measurements of the performance of the explosive in a blastwell are essential for evaluating the effectiveness of a rock-fragmentation round and for computer simulations of the blast. Three techniques are described for interrogating a coaxial-sensor cable placed in the explosive and stem columns. The techniques produced time-distance data from which the initiation time and detonation velocity were determined. The propagation speed of the shock wave in the stem column was obtained from two of the methods. Each method used a standard 50- OMEGA coaxial cable commonly available. The basic operating principles of each technique, installation procedures, and signal-recording methods, as well as examples of specific applications and the interpretation of the signal records are discussed.
