Frequency Electrical Penetrating System
YT120(A) MINE-USED AUDIO FREQUENCY ELECTRICAL PENETRATING SYSYTEM
Applications
. Suitable to detection in mining working face of 200m-400m long
. Detection of water-abundant area within 100m below the floor of mining working face
. Plane distribution scope and depth water-abundant bodies
. Detection of water-abundant area within 100m above the roof of mining working face
. Detection of plane distribution of ancient aquiferous mine and collapsed columns in working face
. Detection of grouting effect
The system is small in volume, easy to carry, easy to operate, convenient to work with, stable and reliable in performance. Its detection results are easy to interpret.
Its combined software has functions of data processing and imaging, can transmit the detected data files to a computer for management. Data processing produces relative apparent resistance rate profile and forms final result image of interpretation.
