An experimental study of the application of the spectral acoustic method to the advance detection of geologic structures in tunnelling working site by Jianguo ZHANG, Zhicheng FENG, Fengqing WEI, Ji MA, Kai ZHAO, Man WANG, Minggong GUO, ШИЛОВ Владимир Иванович

“…Therefore, continuous advanced detection of geological structures is an important technical means to prevent and control coal and gas outbursts in tunnelling working site, and is of great significance to ensure safe production in mines. MethodsBased on the research results of spectral acoustic method in Russia for many years, the resonance phenomenon generated at the weakened contact surface of the roof rock layer by the artificial acoustic signal excited by the coal cutting machine is utilized to construct the prediction coefficient of geological structure based on the stress index and frequency index. …”
