Single point single track high density earth quack exploration data collecting method

Single track, single digital signal detector is adopted in the method to receive signal. The received analog signal is converted to digital signal directly. The converted digital signal is output to signal acquisition station. Arranging and storing the transferred digital signal, the signal acquisition station processes, analyzes and forms geological data. One digital detector is placed at each track, and distance between tracks is 5-10 meter. The invention solves issue that transferring signal through cable, the cascaded type analog signal detector causes signal disturb and signal distortion, and further influencing accuracy of final judgment. The method can carry out transferring signal for long distance in high fidelity. The method raises 20%-50% bandwidth of detection frequency of vibrative dynamic signal for target stratum of coalfield, and 20%-50% bandwidth for target stratum of oil field exploration.
