[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] Such as Figure 1-Figure 4 As shown, the technical solution adopted in the present invention is: a ground-roadway advanced detection method based on nuclear magnetic resonance technology, comprising the following steps:
[0035] Step 1: Select the roadway to be explored, and set the transmitting device on the corresponding surface above the roadway; the transmitting device adopts a large loop coil, and the large loop coil is a rectangular loop coil, according to the location of the roadway to be explored Determine the coordinates of the launch device, and determine the effective area and number of turns of the launch device according to the depth of the roadway to be explored. The transmitting device is set on the ground, which avoids the constraints of underground explosion-proof conditions and roadway space. The distance between the receiving probe ...
