During the measurement, the probe tube of the mine intrinsically safe hand-held borehole locator is matched with the carbon fiber push rod, and is manually pushed into the borehole to realize the measurement of the spatial trajectory and the drilling depth of the borehole. Communicate with mining smart phone through wireless bluetooth, input the attribute information of each drilling hole when drilling, and transmit the data saved in the probe tube memory to the mobile phone after the measurement is completed, and display the drilling hole through the mobile terminal software on site. The spatial trajectory and depth of the hole.
