| Abstract: | Adopted brine as the uniform surrounding rock medium,used a glass tank as roadway space,and established the full space physical model of transient electromagnetic advanced detection.Based on the sectoral scan data acquisition modes of mine transient electromagnetic advanced detection,the advanced detection response characteristics of a good guide cylinder and a low resistance plate was simulated.Results show that:there are some response characteristics of the abnormal body in multi-channel profile,these cha... |
