岩爆、冲击地压的定义、机制、分类及其定量预测模型

引述了若干国际权威学者关于岩爆的机制和定义的论述,在此基础上,依据岩爆发生的不同机制,将岩爆分为断层滑移或者剪切断裂所导致的断裂滑移型和岩石破坏导致的应变型岩爆,并结合事故案例,分析了应变型和滑移型两类岩爆及冲击地压的发生机制和特点。在机制分析的基础上,介绍了岩(煤)柱应变型岩爆和围岩应变型岩爆以及断裂滑移型岩爆定量预测的研究成果,其中,包括作者利用非欧几何模型研究非协调变形影响后对应变型岩爆进行了定量预测和数值模拟的新研究成果。

Definition,mechanism, classification and quantitative forecast model for rockburst and pressure bump

As a review paper, the discourses on the mechanism and the definition of rockburst of authoritative experts were quoted, based on these discourses and according to the different mechanisms of rockburst, rockbursts are divided into the sliding mode rockburst resulting from fault-slip events and strain mode rockburst resulting from the failure of the rock. Combined with the specific accident cases, the mechanism and characteristics of the two types of rockburst are analyzed. Finally, based on the analysis of the mechanism, the quantitative forecast and numerical simulation of rock (coal) pillar strain mode rockburst, enclosing rock strain mode rockburst and sliding mode rockburst are introduced, in which, the author’s latest research of quantitative forecast and numerical simulation for strain mode rockburst after incompatible deformation by using non-Euclidean geometry model is included.
