AI Technical Summary

Technical Problem

Existing borehole measuring equipment suffers from problems such as low measurement accuracy, difficulty in carrying, difficulty in maintaining verticality, inability to compact the inner wall of the borehole, and difficulty in remedying failures to meet depth standards.

Method used

A high-efficiency borehole measuring device was designed, comprising a frame, a borehole measuring mechanism, a wall-pressing mechanism, a drilling mechanism, and a measuring rod. The device achieves accurate measurement and compaction of boreholes by assembling and disassembling the measuring rod, compacting the borehole with a wall-pressing cylinder, deepening the borehole with a drilling mechanism, and combining the device with a laser rangefinder.

Benefits of technology

It enables precise measurement of borehole depth and diameter, avoids measurement errors, compacts the inner wall of the borehole, solves the problem of charge blockage, and can automatically deepen the borehole when the standard is not met, simplifying the operation process.

Abstract

This invention relates to the field of blasting technology, and more particularly to a high-efficiency borehole measuring device and method for mining blasting. The high-efficiency borehole measuring device for mining blasting includes a frame and a borehole measuring mechanism located below the frame. Rollers are installed at the bottom of the frame, and a top seat is installed at the top of the frame. A storage groove is formed inside the top seat, and a measuring rod is movably placed inside the storage groove. A recess is formed in the center of the storage groove. This invention, through the design of the measuring rods, allows for the rapid assembly of several measuring rods, enabling precise measurement of borehole depth. The rods are also detachable and foldable for easy carrying and transport. The wall-pressing mechanism helps to compact the loose soil inside the borehole, preventing the loose soil from falling and causing blockages during subsequent charging. The drilling mechanism allows for simultaneous measurement and borehole deepening, avoiding the hassle of secondary drilling.
