通过实验证明,含瓦斯煤在断裂破坏过程中发生的电磁辐射,是与声发射同源产生的一种能量耗散形式,其辐射强弱取决于外加载荷的大小及煤的物理力学性质,间接反映了含瓦斯煤受力破坏情况,有望成为煤与瓦斯突出危险性预测新指标。
It is proved by experiment that the electromagnetic radiation that occurs during fracture and destruction of gas coal is an energy dissipation form which is homologous with acoustic emission. The intensity of radiation depends on the magnitude of applied load and the physical and mechanical properties of coal, Reflects the destruction of gas containing coal, is expected to become a new indicator of coal and gas outburst risk prediction.
