As one of the dynamic disasters of coal mines, rockburst seriously affects underground safe coal mining. Based on the laboratory test, field test, and theoretical analysis, this study proposed the principle of the rock burst induced by the combination of dynamic and static stresses and divided such rock burst into three types, including induced by primary dynamic stress, mainly induced by dynamic stress, and by dynamic stress in low critical stress state. The expressions of the static stress induced by coal mining and dynamic stress induced by mining tremors were obtained. Moreover, theories and technologies at home and abroad were summarized concerning the monitoring, forecasting, and preventing of rockburst. These mainly include the zoning and leveling forecasting method, electromagnetic radiation technology, elastic wave and seismic wave computed tomography technologies in aspect of rockburst monitoring, as well as the intensity weakening theory, the strong-soft-strong structure effect, the directional hydraulic fracturing technology, the roadway support system in regards of rockburst prevention. The prospect of rockburst development suggested that researches concerning the rockburst mechanism should be quantitatively developed around the roadway and coalface surrounding coal-rock mass. It should be focused on the rockburst mechanism and prevention technology of mining with over 1,000 km deep and mining in large tectonic zone. In addition, the monitoring and prevention of rockburst should be based on rockburst mechanism.
