Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description, but the utility model
It is not limited to these embodiments.
Blast working blasthole position indicator of the present utility model is as shown in figure 1, by support 1, horizontal protractor 2, vertical angulation
Device 3 and lining rope 4 form.Support is made up of stainless steel tube, has a vertical main shaft 5, main shaft upper end is fixed with horizontal angulation
Device fixed disc 6, fixed disc is using main shaft as the center of circle, and circle centre position is provided with vertical horizontal protractor installation axle 7, such as Fig. 2 institutes
Show；The lower end of main shaft 5 is welded with three supporting legs 8, and the support of whole bracket stable is made in the form of triangle on the ground.Support
The one end on leg contact ground is connected with fixed feet 9, and fixed feet is circular or semicircle iron ring, can also pass through gland stone above
Or the stability of other weights increase support.Supporting leg 8 and the junction of iron ring 9 are provided with leveling nut, can by leveling nut
To adjust the left and right of fixed feet, upper and lower distance, with the balance of adjusting bracket.Under normal circumstances, support main axis length takes 1.2m, branch
Spike length takes 30cm, and support feet is in 45 ° with support main shaft.
Horizontal protractor 2 is the center of circle as shown in Figure 3 semicircular protractor with holes, is put through horizontal protractor mounting sleeve
On the horizontal protractor fixed disc of main shaft upper end, fixed by nut and support main shaft, horizontal protractor fixed disc table
Relatively rough material is selected in face, it is therefore an objective to after having adjusted horizontal protractor, can be played a part of necessarily fixing protractor, not made
It deflects.Two air-bubble levels 10 are provided with horizontal protractor, one is used for measuring horizontal protractor left-right balance,
Another is used for measuring horizontal protractor anterior-posterior balance, is remained in the horizontal plane with the horizontal protractor of guarantee.Horizontal angulation
Compass 11 is also equipped with device, when in use the position of 0 ° of recording level protractor, with the horizontal protractor of fixation towards angle
Degree.Horizontal protractor diameter takes 80cm specifications, and protractor is bigger, and the angle number of marking is more accurate on dial, marking number of degrees essence
Exactness is preferably up to 1/4 degree.
Vertical protractor 3 is semicircular protractor as shown in Figure 4 positioned at the horizontal lower section of protractor 2, its size, precision, material
Matter is as horizontal protractor 2.The straight line of vertical protractor is arranged on main shaft 5 by Hinge 12, makes vertical angulation
Device can rotate around the spindle.The pointer outer end of horizontal protractor 2 is fixedly connected by steel wire 13 with the upper edge of vertical protractor plate, is made
The pointer of horizontal protractor and vertical protractor remain the fixation of relative position, can band during the vertical protractor of left-right rotation
The pointer for moving horizontal protractor is swung in the horizontal plane.Vertical protractor 3 has sided scale and a bilateral pointer, bilateral two
Pointer is coaxially disposed in protractor circle centre position, two pointer activities, while two pointer outer ends also link together simultaneously, to protect
Semicircular protractor plate of the card between two pointers can follow pointer to move.Bilateral pointer outer end junction with it is with a scale
Lining rope 4 connects.
The blast working blasthole position indicator application method is：
1. choose fixed measuring point；
As shown in figure 5, the measurement blasthole on explosion step is point to be determined, the fixed measuring point measured on step is then whole
The positioning measurement point of each blasthole of Ge Bao areas.If fixed measuring point and big gun area are located at same level, one can be simply used
Individual semi-circle ruler and a tape measure are positioned, it is contemplated that the complexity of blasting condition, the irregularities in explosion face, for more
Extensively, blasthole positioning is accurately carried out, fixed measuring point is typically higher than explosion face, and blasthole position indicator of the present utility model is in itself
Containing support, so either blast working terminates how rear explosion face changes, be all advantageous to reposition.
Fixed measuring point chosen position will will have a certain distance with burst region, prevent blast action drawing crack heel row area
Domain, cause fixed measuring point to be subjected to displacement, and to ensure fixed measuring point at whole big gun area rear, but can not take in step just
Bottom, prevent concussion of blasting from causing step falling rocks or landslide not only to bury fixed measuring point, and security incident can be caused.If
Step area is small, and suitable fixed measuring point can not be searched out on explosion step, then can be in the upper step at step rear
Or fixed measuring point is found on massif.
Fixed measuring point is chosen at burst region dead astern, if burst region is excessive, is segmented into a few part measurements, often
The measurement point of individual part is all located at the dead astern of each burst region part, in addition, choose will be from for the position in fixation measuring place
Main armament area 10-15m is remote, prevents drawing crack fixed measuring point position after the explosion of main armament area, prevents fixed measuring point from moving forward, and choose
Place is higher than big gun area 20cm or so, also can be artificially padded.After having chosen fixed measuring point, nailed in selected point and easily find color
Iron nail or reinforcing bar, its diameter is less than position indicator support main shaft internal diameter, and stand-down above length is in 11cm or so.
2. fixed blasthole position indicator；
The stainless steel tube of blasthole position indicator support main shaft is enclosed on selected point iron nail, it is more short better to be inserted in depth, avoids
Iron nail aspect effect is to whole holder orientation.
By horizontal protractor towards big gun area, leveling nut is adjusted, makes two level vials of horizontal protractor placed in the middle.Root
According to compass, 0 degree of scale on compass of recording level protractor.
3. measure blasthole；
Lining rope is moved to aperture, measures the distance between fixed measuring point and blasthole, in lining rope drawing process, is driven perpendicular
Straight protractor pointer movement, and vertical protractor swings around support main shaft, and then drive the horizontal protractor beat of pointer.Note
Record the scale of horizontal protractor and vertical protractor, and lining rope scale.All blasthole position indicator is taken away after measurement record.
The position of this blasthole is accurately positioned with three measured value cans of record.
4. position blasthole；
After explosion terminates, if finding blind big gun and blind big gun is capped, after chosen position installs blasthole position indicator, use
Blind big gun is found in the data positioning of record.
If blind big gun localized ground reduces, blind blasthole is in the underface of anchor point.If the rise of blind big gun localized ground it is excessive or
Covering excessively causes ground rise excessive, then blind big gun localized ground is cleared up, then and carry out positioning searching.
Part used in the blasthole position indicator does not include any current emissions, makes simply, and cost is cheap, and measurement is accurate
Degree up to 1~5cm, in vertical core blast working can extensive use, the engineering accident that blind big gun is brought can be reduced to greatest extent.
