探地雷达探测地下采空区的研究

Research on detecting of underground mined-out areas by using GPR

地下采空区的存在严重威胁着地面建筑物和矿山的安全。介绍了探地雷达的原理和技术方法,包括数据采集、数据处理和资料解释,分析了煤矿采空区的地球物理特征及主要的技术难度,结合具体工程实例,探讨了利用探地雷达技术查明地表浅部采空区的效果。

The existence of the underground mined-out areas poses a grave threat to the safety of ground buildings. The paper introduces the principles and techniques of ground penetrating radar (GPR), including data acquisition, processing and explanations. It also analyzes the geophysical features of mined-out coal areas and the major technique trouble problems. Based on specific projects, this paper touches on the effects of the detection to the shallow mined-out areas by using GPR.
