摘要：

Coal and gas bursting is an important factor of causing coal mine safety accident, it may cause major accident, even effect on the safety of human life. Human disturbance is an important factor of causing coal and gas outburst. In this paper under the enlightenment of the water injection dustproof, the coal technology of static high pressure water expanding were researched and developed. And the main equipment of coal and the process flow and the mechanism of rock breaking and the matters needing attention were introduced. Field application showed that the technology can decrease the outburst of the coal and gas and can increase the driving speed. So the technology is effective method of coal mining.
