超声波时距曲线法探测煤体结构类型机理研究

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,准确判断煤体结构类型对于预防煤与瓦斯灾害的发生具有一定的指导意义。但是在准确检测煤体的结构类型的方法仍然存在着不足。本文介绍了一种基于超声反射法判断煤体结构类型的新型探测方法,通过利用时距曲线法实现对煤体超声波速的检测,根据波速与煤体结构类型间的量化关系,实现对煤体结构类型的判断和对煤与瓦斯突出灾害的预测进行指导。

Study of Ultrasonic Reflection Method System on Distinguishing Coal Structur Type

Practics proves that there are close relations between coal structure and coal-gas outburst disasters.It will help us to predict the possibility of the coal-gas outburst that distinguishing the coal structure type accurately.But methods which can accurately distinguish the coal structure type are not perfect.A new method of distinguishing coal structure type based on ultrasonic reflection method is discussed in this paper.The ultrasonic velicity of coal is detected through the trameltime-distance curve method,which will make it realized to distinguish the coal structure type and supervise the the possibility of the coal-gas outburst.
