| 摘 要： | 实践证明煤体结构和煤与瓦斯突出灾害之间存在着密切的联系。但是在可以实现快速、准确判断煤体结构类型的设备开发方面仍然存在不足。介绍了一种基于超声波方法的煤体结构类型检测系统。该系统根据超声波在固体介质中的传播性质，通过对超声波速的测量，实现对煤体结构类型的判断。

| Abstract: | Practics prove that there are close relations between coal sturcture and coal-gas outburst disasters. But machings which can quickly and acuratelly distinguish the coal structure type are not perfect. An ultrasonic testing system for distinguishing coal structure type is descussed in this paper. The system works on the propagation property of ultrasonic spreading in solid. According to the different speeds of ultrasonic the coal structure type can be distinguished by the system. |
