Abstract: Based on the coal seam of 705 working face with danger of dynamic disasters combined rock burst and gas outburst in a coal mine, the idea of using high-pressure water jet to prevent the compound dynamic disaster by a continuous and rotational way was proposed. Theoretical calculation, numerical simulation and site practice were applied to analyze the stress distribution and gas distribution of surrounding rock in roadway. From the view of stress transfer and release and improving the permeability of coal seam, the compound dynamic disaster was prevented in situ test study. The study results showed that the integrated prevention technology can make the high concentrated stress convert into two low concentrated stress; at the same time, it can keep the high concentration of gas drainage for a long time.
