Hand-held Track Instrument for Shallow Drilling in Coal Mine

The hand-held inclinometer for coal mine shallow drilling has been developed. The instrument consists of display controller, probe and conveying rod, can be used to measure track for conveying measurement. The probe can measure the attitude parameters such as dip, azimuth, tool face angle and so on. The display controller works synchronously with the probe to record the depth and time, and the two communicate with the probe via Bluetooth wireless transmission. The final results can be displayed digitally and graphically. The results show that the instrument is steady, reliable and practicable.
