摘要
基于煤岩体脆性变形破坏特征,建立煤岩冲击破坏的弹塑脆性模型,分析了煤岩材料受载变形的稳定破坏和冲击破坏、冲击矿压发生的突发性和延时性,阐释煤岩产生破裂震动原理及现行的地音法、电磁辐射法探测技术的原理及其特征。
Based on the coal s brittle deformation failure characteristics,the paper established elastic-plastic model of coal burst,analyzed the burstiness and time delay of coal damage,explained the principle of earth-sound method and electromagnetic radiation method and their characteristics.
