The invention relates to a roadway rock burst early-warning method based on rock noise monitoring. The method comprises the steps that two rock noise probes are arranged at the interval ranging from 100 m to 150 m in an area with potential burst risks, the distance between the first probe and a stope working face end or a driving working face head-on part is larger than or equal to 30 m, and the two probes alternately move forwards along with the pushing of the working face; whether probe installation and probe noise insulation are qualified or not is detected; rock noise activities are monitored in real time; the energy and frequency monitored by the probe with the lower voice frequency is selected as the rock noise activity energy and the frequency value of the monitored area; whether the working face is in the production period or not is determined; hour or shift shock noise energy and frequency abnormal coefficients in the production period or the non-production period are obtained through calculation; the index value with the larger abnormal coefficient is selected for burst risk evaluation. The roadway rock burst early-warning method based on rock noise monitoring plays a positive role in promoting the development of rock burst prediction and forecast and prevention and treatment technology, and is significant in technical, economic and security benefits.
