Abstract:
Effectiveness of seismic wave signal collection is the precondition for ensuring the accuracy in TSP forecast. In order to improve the signalto noise ratio, the main factors affecting TSP signal collection quality were studied by field test, comparative analysis of field test results, and theoretical analysis method. The influence mode of the fault belt, Rayleigh wave and theanchor coupling of the detecting rod on signal collection were studied. Different coupling methods and anchor strength of the detecting rod have different interferences on signal reception. The single-trace signal method was first applied to analyze the interference characteristics, and the weakening or eliminating interference method of detecting rod coupling methods were also studied. The interference principle of the Rayleigh wave to signal collection was analyzed with the Rayleigh wave theory, and a conclusion was obtained that the Rayleigh wave influence can be significantly weakened with increasing anchorage depth.
Key words: advanced geological forecast; seismic wave; high frequency disturbance; Rayleigh wave; anchor couple
