Zusammenfassung:The invention provides a coal and gas outburst disaster prediction method. The method aims at the occurrence characteristics of vibration stress release briquette coal and gas outburst disasters, considers that most of the coal and gas outburst is affected by vibration stress, gas parameters and an excavation static structure, and comprehensively determines the dangerous area and the dangerous degree of the working face with vibration stress release briquette coal and gas outburst disasters, and the accuracy is higher, and the applicability is higher. 本发明提供了一种煤与瓦斯突出灾害预测方法,针对震动应力释放型煤与瓦斯突出灾害发生特征,考虑到煤与瓦斯突出绝大多数情况下受到震动应力、瓦斯参数和开挖静态结构共同影响,综合确定工作面存在震动应力释放型煤与瓦斯突出灾害的危险区域及危险程度,准确率更高,适用性更强。
