1.问题的提出冲击矿压是矿井巷道和采场周围煤岩体由于变形能释放而产生以突然、急剧、猛烈破坏为特征的动力现象,是煤矿的重大灾害之一。冲击矿压不仅会造成井巷、设备及通风设施的破坏以及人员的伤亡,还可以引起瓦斯、煤尘爆炸、火灾等矿井灾害,强烈的冲击矿压还会造成地面建筑物的破坏和倒塌等。目前,德国、南非、前苏联、美国、波兰、日本和我国等世界上主要的采矿国家都发生过冲击矿压(岩爆)。随着矿井开采深度的不断增加,冲击 1. The question is put forward The rock burst is a dynamic phenomenon characterized by sudden, drastic and violent destruction due to the release of deformation energy. It is one of the major disasters in coal mines. Impact rock pressure will not only cause damage to the shaft, equipment and ventilation facilities and casualties, but also cause gas disasters such as gas explosion, coal dust explosion and fire disaster. Strong rock burst can cause damage and collapse of ground structures. . At present, rockbursts have occurred in the major mining countries in the world such as Germany, South Africa, the former Soviet Union, the United States, Poland, Japan and China. With the continuous increase of mining depth, impact
