Description

Technical Field

[0001] This utility model relates to the field of open-pit blasting, and in particular to a pressure-balanced capillary tube device for measuring the water depth of blast holes. Background Technology

[0002] In open-pit blasting operations, problems such as insufficient supply of water-resistant explosives and inaccurate charge structure design often occur, which prevent the explosives from exerting their full explosive power, affecting the blasting effect and post-blast quality, and creating a step foundation that requires secondary blasting treatment.

[0003] The task of deep hole surveying is to calibrate and accept deep holes according to design requirements. The general process of deep hole surveying is as follows: calibrate the chamber location; draw a plan of the chamber, transferring the position of the drilling rig column inside the chamber onto the drawing, and delineate the blasting boundary; design the deep hole, determining the azimuth (azimuth angle α or horizontal angle β), inclination angle σ, and hole depth L; calibrate the deep holes, marking the hole positions on the chamber wall with paint; accept the deep holes, measuring the azimuth, inclination angle, and hole depth of each hole (if the measured results differ significantly from the design data, affecting ore recovery, the hole will not be accepted); finally, draw the deep hole plan and cross-sectional diagrams based on the acceptance data. The next step is to determine the charge quantity and carry out deep hole blasting.

[0004] Existing pressure-balanced capillary tube devices for measuring borehole water depth suffer from inaccurate depth measurements, long measurement times, and an inability to quickly detect depths, which affects subsequent blasting operations. Furthermore, the depth detection devices are inconvenient to use, complex to operate, and reduce efficiency. Utility Model Content

[0046] The working principle of the pressure-balanced thin tube device for measuring the water depth of a borehole provided by this utility model is as follows: First, the operator picks up the winding frame 31, aligns the thin tube 2 with the upper side of the low-level water accumulation 1, and slowly puts the thin tube 2 into the low-level water accumulation 1.

The auxiliary pressure roller 36 is used to facilitate the passage of the connecting rope 35 for winding. After the device connects the thin tube to the counterweight, it is placed in the hole, so that the sand-proof filter end sinks to the bottom of the water-bearing borehole. At this time, both ends of the thin tube are in an open state, and the water in the hole flows in from the bottom of the thin tube. Under the action of atmospheric pressure, the liquid level in the tube is level with the water level in the borehole. The other end of the thin tube is used. The hollow round tube 41 is used to connect to the connecting pipe 45, which is used for air intake and exhaust. The control valve 46 is used for control of the switch. The sealing airbag 43 is used to seal the thin tube 2, and the sealing strip 44 is used for sealing. The sealing is fixed by the expansion and contraction of the sealing airbag 43. Then, the part of the thin tube inside the hole is slowly rolled up using the tube winding mechanism. The tube body must not be bent during the rolling process. Because of the pressure balance of the sealing air at the top of the thin tube and the increased surface tension of the water inside the tube by the filter screen at the bottom of the thin tube, the water in the thin tube can be retained. The height of the water in the borehole can be read by the scale on the thin tube for use.

[0047] It is worth noting that the core chip of the external control switch group disclosed in the above embodiments is a PLC microcontroller, the power motor 33 is a servo motor, and the external control switch group controls the operation of the power motor 33 using methods commonly used in the prior art.
