| 摘 要： | 设计了一个由混凝土、矿粉和尾砂等材料制成的带空洞的实验模型.在模型的预留空洞中,分别充填水、砂、泥和空气进行了模拟实验,研究不同充填介质在探地雷达探测图像中表现出的特征及差异,进而辨别不同充填介质.论述了采空区探地雷达探测原理与方法,并通过在甘肃厂坝铅锌矿进行现场试验,分析、识别了采空区内充填物类型及状态.实践表明,应用探地雷达技术,可以高效、准确地探测采空区及其充填情况.

| Abstract: | An experimental model with two cavities was made of concrete, ore fines and tails in the laboratory. Simulation experiments were conducted to study the characters in Ground Penetrating Radar (GPR) images of every filling body by filling water, sand, mud and air in turn. Experimental results indicate the radar image changes with gob filling. Field investigations were carried out at Changba Lead-zinc Mine in China. The main detecting method for gob and its filling by GPR was expounded. The space distribution of gob was obtained. The filling can be well identified by analyzing the radar images. The results of field experiments show GPR technique is useful, high-efficiency and nondestructive for detecting gob and its filling. |
