摘　　要：声发射技术是研究岩石变形破坏微观机理的重要手段,对开采扰动下采空区煤岩破裂失稳的机制和前兆预测具有重要意义。基于声发射定位实验,利用支持向量机方法,对煤岩单轴抗压破裂与失稳过程中的声发射信号进行分析与预测,为采空区煤岩破裂定量化预测提供科学依据。Acoustic Emission （AE） technique is an important means to reveal the micro-mechanism of rock deformation and failure and is of great significance to the study of the mechanism and forecast of the crack and destabilization of coal-rock in the mine-out area caused by mining. Based on the test of AE location and by using vector support machine, analysis and forecast were made of AE signals in the coal-rock uniaxial compressive crack and destabilization process so as to provide a scientific basis for the quantitative prediction of crack of coal-rock in the mined-out area.
