Detector for Hole Depth and Fault of Drill Pipe with Cable

Facing with the detection problem of hole depth and fault of drill pipe with cable, and in order to fast detect and test depth of hole and detect fault of drill pipe with cable, we develop the integrated detector that can solve both problems at the same time under coal mine. By introducing detection principle, physical design and operation method under different conditions of detector, we analyze test results of the detector in the field test and the direction for future development.
