YZGW12.8 Mining Borehole Trajectory and Methane Concentration Measuring Instrument

The YZGW12.8 Mining Borehole Trajectory and Methane Concentration Measuring Instrument is an intelligent multi-functional in-situ detection device for borehole trajectory, gas concentration, and extraction negative pressure. The instrument mainly consists of an intrinsically safe multi-functional mining probe, a mining smartphone, a stainless steel push rod, and a borehole mouth sealer. During measurement, the borehole mouth sealing device is installed on the tee joint of the gas drainage pipe. The push rod passes through the borehole mouth sealer and connects to the probe, pushing the probe to travel inside the hole, thereby achieving in-situ measurement of the spatial trajectory, depth, gas concentration along the borehole, and extraction negative pressure. The measured data are stored in the probe. After measurement, the probe is retrieved, and the mining smartphone acquires the measured data from the probe via wireless Bluetooth, displaying on-site the borehole trajectory chart, the gas concentration curve along the entire borehole, and the extraction negative pressure curve.
