Description
Technical field
The utility model relates to a kind of layout instrument of arranging surface blasting big gun hole site, is applicable to the layout of the surface blasting operation such as surface mine, stone pit big gun, is specially adapted to the work of surface blasting cloth hole, mine.
Background technology
Mine surface blasting is to utilize the detonation of explosive to carry out fragmented rock body, is the most effective and most widely used rock excavation of one in current mining process, peels off means.Cloth hole is the important ring in whole surface blasting, and reasonably good blasting condition can be created in cloth hole, reduces boulder yield, reaches satisfied demolition effect.Otherwise, if cloth hole quality is not good, blasting condition is just relatively poor, although these problems can be carried out suitable adjustment to make up its shortcoming and defect in ore production and processing operation afterwards, but due to explosion genetic prerequisite defect, demolition effect still can be poor.Therefore, cloth hole quality is very remarkable on the impact of demolition effect.
In addition, cloth hole work is the imbody of blasting parameter design philosophy in practical operation, is also the foundation of perforation instruction issuing, therefore, once arrangement of boring holes scheme determine, rig will be by the operation of boring a hole of its design.So position, hole is after arranging, this work has unalterable feature to a certain degree.The whether reasonable of an arrangement of boring holes is directly connected to perforation expense, blasting cost, digging cost of transportation, secondary blasting expense in the future, and has direct relation with demolition effect.Therefore, considerable status is occupied in cloth hole in whole drilling and blasting operation.
But the surface blasting cloth hole work at present also main instruments such as tape measure that rely on is arranged one by one, construction relative complex, labour intensity is large, and operating efficiency is low, and certainty of measurement is relative with accuracy poor, be easy to cause explosion adverse consequences, seriously restricted high-efficiency mining and the production safety of enterprise.
Summary of the invention
In order accurately to determine the position, hole in blasting design scheme, can accurately determine the angle between pitch-row, array pitch and big gun hole, raise labour efficiency, improve demolition effect, improve mine productivity effect, the utility model proposes a kind of cloth hole instrument that can accurately arrange surface blasting big gun hole site.
For realizing above-mentioned purpose of the present utility model, the cloth hole instrument that the utility model is a kind of can accurately arrange surface blasting big gun hole site by the following technical solutions.
A kind of cloth hole instrument that can accurately arrange surface blasting big gun hole site of the utility model is to be constituted by 360 ° of wholecircle protractors, hollow arbor braid pin-and-hole mobile jib, expansion link, tripod.Hollow arbor braid pin-and-hole mobile jib is two, top-bottom cross layout, and pin-and-hole is positioned at the centre position of rod member; Between 360 ° of wholecircle protractors and hollow arbor braid pin-and-hole mobile jib, adopt pin to connect, level is installed on tripod; Hollow arbor braid pin-and-hole mobile jib two ends are connected by internal thread with expansion link; Described expansion link is marked with rule.
Described hollow arbor braid pin-and-hole mobile jib and expansion link are all light hollow metal tube; The length of hollow arbor braid pin-and-hole mobile jib is 1～3m, generally selects 2m.Length after expansion link full extension is generally 8～9m.
Described expansion link is to be formed by many lightweights, hollow, metal tube with scale socket, and the accuracy that expansion link is marked with rule is centimetre.
A kind of cloth hole instrument that can accurately arrange surface blasting big gun hole site of the utility model can accurately be determined Holespacing, array pitch and angular relationship by dial and 360 ° of wholecircle protractors of telescopic rod, reach the object of determining more accurately big gun hole site, realize rapidly and efficiently cloth hole operation, obviously improve demolition effect.Meanwhile, can also be used for the surveying work of slope angle etc.
In addition, the utility model can not only accurately be determined big gun hole site according to slope angle, and has easy to carry, simple to operate, safe and reliablely, can significantly improve efficiency, reduces enterprise's production cost, creates good economic benefit.
