Mining intrinsically safe drilling trajectory measurement device, coal industry specific instrument

The intrinsically safe drilling trajectory measurement device for mining is an intelligent real-time drilling trajectory detection equipment. The instrument mainly consists of a non-magnetic drill rod, a probe tube, and a mining smartphone. The probe tube is installed inside the non-magnetic drill rod, and the two ends of the non-magnetic drill rod are respectively connected to the mining drill rod and drill bit, realizing the measurement of the spatial trajectory and drilling depth of the borehole while drilling.

n working principle

YSZ11.1 Mining Drilling Trajectory MeasurementdeviceIt is an intelligent real-time drilling trajectory detection device, mainly composed ofnon-magneticdrill pipe、probeandMining smartphonesgroupCheng,probeInstalled in non-magnetic environmentdrill pipeInternally, non-magneticdrill pipeBoth ends are separate from each otherOn the mineConnect the drill rod and drill bit to measure the spatial trajectory and drilling depth of the borehole while drilling.probeBy communicating with mining smartphones via Bluetooth, the attribute information of each borehole is obtained during drilling, and will be saved after drilling and exitingprobeThe data stored in the memory is transmitted to the mobile phone, and the spatial trajectory and depth of the borehole are displayed on-site through the mobile terminal software. The drilling depth can be measured by entering the rod and counting at the same time through mobile terminal software, or byprobeThe built-in depth sensor automatically measures without manual intervention, truly eliminating false drilling and empty drilling.
