Rock burst is one of the coal and rock dynamic phenomena occurred in mining. The underwater coal mining of dam encounters frequent and drastic underwater impacts, which seriously affects the safety of mining. Studying of law of rock burst appears extremely urgent, which is of great significance to ensure safety in coal mines. The impact stability model is used to analyze the coal and rock impact tendency characteristics of underwater coal mining. The validity of the simulation model is verified by experiments. Experiments show that the designed impact stability model can effectively detect the coal and rock impact value, and the model ensures the safety of mining by monitoring, forecasting and relieving the risk of rock burst.
