摘要
///In order to design a new multi-wave and multi-component seismic exploration system,the authors analyzed some problems in applying DTC-150,obtained the effective frequency range of coal rock and the effective layout plan of the observation system on the basis of analyzing large amounts of engineering forecast data in combination with studying four key technologies,developed a high speed and high precision multi-channel data acquisition and processing system,gave the blind spot where the working face diffraction echo is formed and the tunnel sound wave processing method,and proposed the conditions under which the working face diffraction echo and the direct wave do not overlap.
