Abstract
Based on the excavation of rock tunnel in Da’anshan coal mine, the paper carried out the vibration monitoring on blasting excavation is carried out in the rock tunnel. Through analyzing the time and frequency of the monitored blasting seismic wave by HHT transformation, the energy distributions of blasting vibration characteristics and seismic wave are obtained, which provides a strong basis for the establishment of rock absorption measures and safe excavation in rock tunnels.
