Study on the Outburst Regional Prediction and Effect of Daning Coal Mine
Coal and gas outburst which threatens coal mine safety production is a kind of complicated dynamical phenomena in mining and one of the most serious natural disasters. It is indicated by domestic and overseas mining practice that coal and gas outburst is regional distribution and the disaster occurrence area accounts for only 8%-20% of whole mine district Based on the regional prediction, the mining area was then divided into coal and gas outburst dangerous area threat area and safety area The productivity is increased through difference method. But the applicability and reliability of it have not method to proof. In this paper, using the prediction index proof the conclusion of regional prediction. It is very useful to us while adopting the rational measure for prevention outburst. Then, the quantity of construction is reduced.
