Abstract
The utility model discloses a blast hole depth measuring device, which resolves the technical problem that the mining cost is increased due to the fact that the depth of each blast hole is different and the surfaces after blasting are not at the same level. The blast hole depth measuring device comprises a blast working surface (6) and a blast hole (1) drilled on the blast working surface (6). The utility model is characterized in that a hole depth measuring rod (2) is disposed in the blast hole (1); a slide seat (3) capable of sliding up and down on the hole depth measuring rod is movably arranged on the part of the hole depth measuring rod (2) extending outside of the blast working surface (6); a swinger acceptor (4) is arranged on the slide seat (3), and a swinger (5) is arranged on the blast working surface (6). The utility model is advantageous in that the surface after blasting is level; the mining cost is reduced.
Description
Technical field
The utility model relates to a kind of device that the explosion hole depth that gets out on the mine blasting workplace is measured.
Background technology
Blasting work is very important for the mine, and it directly influences the cost of mining, concerns the height of mining profit.On the blasting work face, to bore many blast holes before the explosion, the explosive of packing in these holes is implemented explosion then, and is often inconsistent because of each explosion hole depth of implementing explosion simultaneously in the explosion implementation, make the face that forms after the explosion not at grade, increased the cost of mining.
Summary of the invention
It is inconsistent because of each explosion hole depth of implementing explosion simultaneously that the utility model provides a kind of explosion hole depth measurement mechanism to solve in explosion is implemented, thereby cause the face that forms after the explosion not increase the technical matters of mining cost at grade.
The utility model overcomes the above problems by following scheme:
A kind of explosion hole depth measurement mechanism, comprise the blasting work face, the blast hole that on the blasting work face, gets out, in described blast hole, be provided with the hole depth sounding rod, be movably set with the slide that can on the hole depth sounding rod, slide up and down on the hole depth sounding rod of blasting work face exceeding, slide is provided with the scanner receptacle, and the blasting work face is provided with scanner.
Described scanner and scanner receptacle correspondence are provided with and transmit and receive the horizontal survey telltale.
The utility model has solved the accurate problems of measurement of explosion hole depth, makes the face that forms after the explosion smooth, has reduced mining cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Specific embodiment
A kind of explosion hole depth measurement mechanism, comprise blasting work face 6, the blast hole 1 that on blasting work face 6, gets out, in described blast hole 1, be provided with hole depth sounding rod 2, be movably set with the slide 3 that can on the hole depth sounding rod, slide up and down on the hole depth sounding rod 2 of blasting work face 6 exceeding, slide 3 is provided with scanner receptacle 4, and blasting work face 6 is provided with scanner 5.
Described scanner 5 and scanner receptacle 4 correspondences are provided with and transmit and receive the horizontal survey telltale.
Blasting work is very important for the mine, and it directly influences the cost of mining, concerns the height of mining profit.And blast hole depth is more importantly for the influence of demolition effect.Because the bottom of blast hole is on same plane, the face out-of-flatness that forms after the explosion.Use scanner as survey instrument, with about 6 meters sounding rod patchholes inside, the groundwork principle is: the height of putting down with scanner is a benchmark, and then sets the level altitude position on the sounding rod, this position is the height that the scanner height deducts next platform, adds super dark.When measuring receiver is moved up and down on sounding rod, in case the position suitable receiver will ring, hole depth the slag that just need rockfill enter, can allow rig beat again inadequately.This mode is different from rope, and rope bends in the hole easily, causes the degree of depth in hole inaccurate.
After measuring with the utility model, each hole has all reached on the same plane, and demolition effect is much better, and very smooth of ground, has reduced mining cost.
Claims (2)
1. explosion hole depth measurement mechanism, comprise blasting work face (6), the blast hole (1) that on blasting work face (6), gets out, it is characterized in that, in described blast hole (1), be provided with hole depth sounding rod (2), be movably set with the slide (3) that can slide up and down on the hole depth sounding rod (2) of blasting work face (6) exceeding on the hole depth sounding rod, slide (3) is provided with scanner receptacle (4), and blasting work face (6) is provided with scanner (5).
2. a kind of explosion hole depth measurement mechanism according to claim 1 is characterized in that, described scanner (5) and scanner receptacle (4) correspondence are provided with and transmit and receive the horizontal survey telltale.
