    • PROBLEM TO BE SOLVED: To investigate a situation in the vicinity of a bolt tip desired most to be investigated, while avoiding an disturbance due to a rock volt drilled into the ground.
      SOLUTION: In this underground radar survey method, an electromagnetic wave Ew of prescribed frequency is emitted from a transmission antenna SA arranged on a ground surface GS, into the ground G, and an underground reflected wave Grw reflected with the electromagnetic wave Ew emitted into the ground G, in a reflection point in the ground G, is received by a reception antenna CA arranged on the ground surface GS, a visualization data of underground structure is composed based on a received reflection time and a waveform indicating an intensity of the reflected wave to from an image. At least one of the transmission antenna SA and the reception antenna CA is brought into contact with a base end of the rock bolt RB implanted in the ground G, and at least one of the transmission of the electromagnetic wave Ew and the reception of the underground reflected wave Grw is carried out via the rock bolt RB, in the underground radar survey method.

    • 要解决的问题:在避免由于钻进地面的岩石伏击引起的扰动的同时,调查最需要研究的螺栓尖端附近的情况。 解决方案:在这种地下雷达测量方法中,规定频率的电磁波Ew从布置在地面GS上的发射天线SA发射到地面G,并且用电磁波Ew反射的地下反射波Grw 发射到地面G中的地面G中的反射点由布置在地面GS上的接收天线CA接收,地下结构的可视化数据基于接收到的反射时间和表示强度的波形 反射波从图像。 发送天线SA和接收天线CA中的至少一个与植入地面G的岩石螺栓RB的基端接触,并且电磁波Ew的发送和地下接收中的至少一个 反射波Grw通过岩石螺栓RB进行,在地下雷达测量方法中。 版权所有(C)2008,JPO&INPIT
