煤与瓦斯突出事故破坏性的灰色预测

o master the next two years China coal and gas outburst accident destruction and development trend, with the 2005-2010 coal and gas outburst accident death toll as the basis, establish the grey prediction model GM (1, 1). By accident death toll as destructive index, by estimating the future death toll, predict two accident of coal and gas outburst risk of accidents and its development trend. The predicted results indicate that the 2011, 2012 China coal and gas outburst accidents could death toll respectively for 224 people, accidents, 222 destruction and 2010, reduced lower than 1.3%, 2.2%.
