Method and apparatus for determining blaster detonation time and first arrival time of seismic wave |
摘要 |
The present invention comprises an apparatus and a method for measuring the first arrival time of seismic waves from detonation in seismic explorations, comprising a or several detectors for measuring seismic waves and converting them into electrical signals and a signal processing means for calculating an average energy of the electrical signals to determine the first arrival time of seismic waves and using a smooth filtering method to compute accurately the first arrival time backwards from the first maximum valve in the average energy curve.
