实践证明,参与冲击地压的煤、岩都具有采种发生冲击式破坏的能力,这种能力称做煤岩的冲击倾向。它是煤岩材料的固有属性。如果设法改变煤岩材料的结构,其结果会改变煤岩的性质。研究证明,水的作用能够显著改变煤岩性质。本文讨论了水对煤岩强度特性及变形特性的影响,重点介绍了在实验室内煤岩试件在不同时间浸水状态下,冲击倾向特性的变化规律及试验方法,同时阐述煤层注水可减缓或消除冲击地压危险的机理。 Practice has proved that coal and rock involved in rockburst have the ability to impact the type of mining damage, this ability is called the impact of coal and rock. It is an inherent property of coal rock material. If you try to change the structure of coal rock material, the result will change the nature of coal rock. Studies have shown that the effect of water can significantly change the nature of coal and rock. In this paper, the influence of water on the strength and deformation characteristics of coal and rock is discussed. The changing rules and experimental methods of impact tendency of coal and rock specimens in laboratory are introduced emphatically. At the same time, Mechanisms to eliminate the danger of rockburst.
