In the described a step, detection line of elder generation's testing, by surveying the measurement markers place that measured track pitch is embedded in detection line, a plurality of wave detectors are connected with seismic instrument by light/cable with wave detector, the seismic event that the earthquake that is received by the lasting record of seismic instrument wave detector produces.
In the described b step, background registration is meant that the physical prospecting field acquisition does not initiatively excite, and writes down the data of acquisition with seismic instrument, and what seismic instrument write down is the seismic event that external environment condition or natural vibrations form.
In the described b step, identify the seismic event that earthquake produces according to path of seismic wave, whilst on tour, amplitude, frequency, waveform character.
In the described c step, earthquake is divided into " red, yellow, yellowish-white, white " four ranks by intensity, and the corresponding colour code of definition, the different dB scope of the corresponding earthquake instrument screen surveillance gain of each rank colour code.
Employing the invention has the advantages that:
One, the present invention monitors the seismic event that earthquake produces, utilization is in the earthquake period happening with increasing frequency, there is quiet period between the earthquake continuously, the seismic event that the identification earthquake produces, quantitatively judge earthquake intensity, the on-the-spot earthquake monitoring of field earthquake prospecting collection dopes the quiet period that exists between the continuous earthquake, thereby carries out field earthquake prospecting collection in the aftershock quiet period.
Two, among the present invention, the seismic event that the identification earthquake produces in background registration has been got rid of the seismic event that the physical prospecting artificial excitation produces, and makes the accuracy of monitoring result be higher than existing earthquake detection method far away.
Three, the present invention is by analyzing the aftershock frequency and intensity, with the seismic wave energy that identifies by the classification of dB scope, dB scope by classification can be predicted the quiet period that exists between the continuous earthquake, thereby can carry out field earthquake prospecting collection in the aftershock quiet period.
Four, the present invention is by with the aftershock energy cascade, and makes it corresponding with aftershock intensity colour code, makes collection site have real-time, applicability, high efficiency, makes that collection site can real time discriminating aftershock intensity and the aftershock quiet period, instructs and ensure the collection operation in real time.
Five, the present invention can judge the earthquake strength that will take place in advance, thereby can carry out preventive protection to job facilities, is particularly useful for the operation of implementing that carry out in zone more wide in the physical prospecting field acquisition, interim.
