Design of Hole Depth and Wireline Drill Pipe Fault Detector

Abstract:
Aiming at the problems of hole depth detection and wireline drill pipe fault point detection in coal mine underground drilling construction, in order to quickly detect and verify the depth of a single borehole and detect the fault type and fault point position of wireline drill pipe, an integrated coal mine hole depth and wireline drill pipe fault detector is designed, which can solve these two problems at the same time. The structure design and the application mode applied to the construction of conventional rotary drilling and horizontal directional drilling, and the application effect and future development direction of the instrument in the field test are analyzed.
