The invention relates to a rock burst monitoring and early warning method of underground mining, and belongs to the technical field of mine rock burst monitoring and early warning. The rock burst monitoring and early warning method comprises the following steps that step 1, parameters of an underground tunnel and a mining working face of a mine are determined; 2, a mine microseismic monitoring system is established; 3, geostress in the mining process is determined; 4, the microseismic activity rate in the mining process is determined; 5, the increment of the geostress and the microseismic activity rate per unit time in the mining process is determined; 6, geostress loading microseismic response rate parameters in the mining process are determined; and 7, the rock burst monitoring and earlywarning criteria in the mining process are determined. The rock burst monitoring and early warning method has the beneficial effects that the geostress and the microseismic activity rate of the underground mining engineering
