| 摘 要： | 基于目前煤与瓦斯突出区域预测采用的指标中的不足,提出了初始释放瓦斯膨胀能指标,从能量学的角度解释了煤与瓦斯突出。通过实验模拟以及现场的实际验证,证明此指标的预测准确率达90%以上,初始释放瓦斯膨胀能方法很好地弥补了现行区域预测指标的不足。

| Abstract: | For the shortcoming in current index for regional prediction of coal and methane burst,this paper put forward an index of preliminary released methane dilatation energy and explained coal and methane burst from energy science.Experimental simulation and on-the-spot application showed that its prediction accurate ratio reached 90%.The method of preliminary released methane dilatation energy covered well the shortage of current regional prediction index. |
