随着煤矿开采深度不断增加,煤矿受冲击地压灾害影响日益凸显,因此冲击地压防治引起高度重视。冲击地压是一种特殊的矿山动力现象,是指采掘场所围岩内聚集大量弹性能,当超出极限强度时,围岩迅速释放能量,表现为煤岩突然被破坏,破坏巷道和工作面,造成巨大人员伤亡和财产损失,冲击地压是威胁煤矿安全生产的重大灾害之一。现总结了煤矿采掘中冲击地压的特征、分类、原因、预测及治理技术,为冲击地压的防治起到借鉴作用。
As the depth of coal mining continues to increase, coal mines have been increasingly highlighted by the impact of rock burst. Therefore, the prevention and control of rock burst has drawn great attention. Rockburst is a special kind of mine dynamic phenomenon, which means that a large amount of elastic energy accumulates in the surrounding rock of the excavation site. When the ultimate strength is exceeded, the surrounding rock rapidly releases energy, which results in the coal rock suddenly being destroyed and the roadway and working face being destroyed. Causing huge casualties and property losses. The impact is one of the major disasters that threaten coal mine safety in production. Now summarizes the characteristics, classification, causes, prediction and treatment technology of rock burst in coal mining, which can be used as a reference for the prevention and control of rock burst.
