Description
Technical field
The present invention relates to mine mining field, in particular to a kind of townhouse hole cutting groove forming process.
Background technique
With the development of industry, metal demand amount is consequently increased, and mineral industry is also greatly improved, mining process
In, the demolition effect of cutting groove is very significant considering that ore recovery ratio and explosion block uniformity, the demolition effect of cutting groove
Good, ore recovery ratio height, blast fragmentation size are more evenly.
Currently, common cutting groove forming technique, which cuts kerve method, scallop hole for courtyard, raises into channel process and wedge by angle
Shape kerve method.It is using courtyard as the scope of freedom of explosion and compensation space, with shallow bore hole, medium-length hole, major diameter that courtyard, which cuts kerve method,
Deep hole etc. carries out explosion and forms cutting groove, and entire driling explosion is all to carry out in the chamber of cutting groove upper end, but early period digs
Chamber heavy workload, rock penetration performance is low, long construction period, and construction cost is higher.Scallop hole raises into channel process and wedge shape by angle
Kerve method beats the blasthole of differing tilt angles applying man-hour requirement, then explosion forms cutting groove, simple process, but construction period
Long, construction cost is high.
Patent No. CN201610384398.2 discloses a kind of quick formation process of big structure stope cutting groove, including with
Lower step: 1) Slice stoping: the high 80-150m of stope, width 20-25m, length is orebody thickness, is divided into 4 layerings, and layering is high
Degree is 20-30m；2) cutting lane arrangement: cutting lane is arranged in disk end on stope；3) it cuts well arrangement: cutting well and be arranged in stope and cut
The side of crosscut is cut close to stope boundary or is arranged among stope cutting lane；4) cutting groove is formed: quick-fried using medium-length hole
Broken technology shaft formatting by one blasting, cutting lane explosion quickly form cutting groove using method from top to bottom.The technique is to cut well
For the scope of freedom, successively explosion formation cutting groove, complex process, explosion number are layered using cutting well and the medium-length hole for cutting lane
More, heavy workload, construction efficiency are low.
Therefore, it is badly in need of a kind of novel cutting groove manufacturing process, to reduce the construction cost of mining, improve construction efficiency.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide a kind of forming of townhouse hole cutting groove
Method, this method using townhouse hole as scope of freedom explosion after form cutting groove, it is simple process, high-efficient, effectively reduce mining
Workload shortens construction period.
The technical solution adopted by the present invention to solve the technical problems is: a kind of townhouse hole cutting groove forming process, including with
Lower step:
1) Volleyball Association's round is formed using the impactor with guiding device；
2) in the several blast holes of two sidetrackings in townhouse hole；
3) using Volleyball Association's round as the scope of freedom, then successively the blast hole of explosion scope of freedom two sides forms cutting groove.
Further, the impactor with guiding device includes impactor ontology and guiding device, the guiding device
Including guide rod and the impactor casing being fixedly arranged on guide rod, the impactor casing is set on the impactor ontology,
The impactor ontology includes drill bit and drilling rod, and the guide rod is equipped with groove, and the radius of the drill bit is greater than outside guide rod
The distance between the axis of wall and impactor ontology, and it is less than the distance between the axis of groove and impactor ontology, the brill
The left side of head is located in the groove.
Further, the step 1) forms the specific steps of Volleyball Association's round are as follows:
A) upward pilot hole is bored in production face with drilling machine；
B) by the guide rod insertion pilot hole of guiding device, impactor ontology is installed；
C) first drilling hole is bored upwards with impactor ontology, pilot hole and first drilling hole form townhouse hole；
D) guide rod of guiding device is inserted into first drilling hole again, installs impactor ontology；
E) second drilling hole is bored upwards with impactor ontology, and so on, Volleyball Association's round can be formed.
Further, the blast hole is symmetrically provided with the two sides in townhouse hole.
Further, the sequence of step 3) borehole blasting hole explosion are as follows: the explosion of side in the middle part of townhouse hole described in first explosion
The blast hole of the other side in the middle part of hole, then explosion townhouse hole, then explosion simultaneously are opened in close to the two sides on one side in the middle part of townhouse hole
Blast hole, last explosion simultaneously are opened in the blast hole close to the two sides of another side in the middle part of townhouse hole.
It is preferred that the quantity of the blast hole be 6, the blast hole include the first hole, the second hole, third hole, the 4th hole,
5th hole, the 6th hole.
Further, first hole, the second hole and third hole are located in same level, the 4th hole, the 5th hole and
6th hole is located in same level, and first hole and the 4th hole, the second hole and the 5th hole, third hole and the 6th hole are right respectively
Claim the two sides for being set to the scope of freedom.
Further, the blasting sequence of the blast hole is followed successively by the second hole, the 5th hole, third hole, the first hole, and the described 4th
Hole and the explosion simultaneously of the first hole, the 6th hole and the explosion simultaneously of third hole.
Further, the blast hole is 1.5-1.8 meters with a distance from the scope of freedom, and the distance between two neighboring blast hole is
1-1.5 rice.
Further, the blast hole is 1.5 meters with a distance from the scope of freedom, and the distance between two neighboring blast hole is 1.2
Rice.
According to composite factors such as toe burden, Blasting height (step height), aperture, explosives, determine blast hole to certainly
It is 1.5 meters by the distance in face, the distance between two neighboring blast hole is 1.2 meters, is to rely on to form 3 meters × 3 with the scope of freedom
The cutting groove of rice, toe burden is excessive, and backlash also increases；Toe burden is too small, not only increases boring work amount, wave
Take explosive, and operation is dangerous.
A kind of townhouse hole cutting groove forming process of the present invention the utility model has the advantages that the present invention passes through with the band for being capable of forming townhouse hole
Have guiding device impactor formed Volleyball Association's round, then using townhouse hole as scope of freedom explosion after form cutting groove, the cutting groove
Simple process, the strong operability of manufacturing process, and its explosion number is few, reduces the workload of scope of freedom formation, saves
Blasting cost improves construction efficiency.
