Abstract：The transmitting and attenuation laws of stress wave in rocks are important and hot research issues in geotechnical engineering and mining engineering. The major reason that roadway or working face is destroyed by rockburst is also the transmitting wave of earthquake tremor. Using TDS–6 seismic experiment instrument，the experiment on the transmitting law of earthquake tremor is carried out for different rocks；and energy attenuation curve is achieved with analyzing the different above-mentioned curves. Experimental results reveal that shock energy attenuates exponentially with the distance from the explosive center. The energy attenuation index h is considerably small in intensified rock and soil media，but much larger in weak or soft media apparently. The energy attenuates quickly in the beginning，and it will disappear after certain distances. These conclusions provide the theoretical basis for studying the failure mechanism of roadway surrounding rock subjected to rockburst and forming the control principle of strong-soft-strong structure for roadway to prevent rockburst.
