Abstract
The utility model discloses an ore crusher which is applied to the secondary mining explosion of big ore in a mine. The utility model is characterized in that the processes of drilling and shooting are relieved; the utility model utilizes the mixture of an emulsion explosive and an energy cantaining constituent as a main charging which is loaded into a charging casing body which is made of plastic. The bottom surface of the charging casing body is a hollow spherical-surface-shaped energy gathering cavity. By practical tests, the utility model has the advantages of simple charging result, simple use, lower labor strength, high safety, good crushing effect, low explosion cost, little environmental pollution, and is novel generation replacement product which is used for the secondary mining explosion in the mining.
Description
The utility model is applicable to the new utensil that mine rock second-time breakage is adopted.
The continuous development of the industry of surface mining in recent years, the mining scope is dwindled gradually, and artificial rock drilling punching is continued to use in traditional second-time breakage, uses 2
#The method of tnt explosive explosion, this method not only labor strength is big, and the working environment of workers is abominable, and the effect of second-time breakage is also bad, and the danger that slungshot is hurted sb.'s feelings also takes place sometimes, adds and adopts 2
#Produce huge vibrations during the tnt explosive dobie, also have glass in various degree bad facility on every side.Chinese patent discloses and a kind ofly is applied to the broken tool (CN86 201382U) of ore deposit rock of mine big ore the second mining explosion with the hollow charge technology, has removed the process of drilling and blasting from.But it is because used main charge adopts the very high high explosive of cost, and when the compacting booster gains, has certain danger; The aspect charge constitution designs more complicated in addition, as comprises main medicine column, pair powder column, booster gains, dividing plate, cover metal etc.
The goal of the invention that this is novel, provide and a kind ofly need not drill and blast, reach the purpose of broken large rock mass, both simple in structure, easy to use, crushing performance is effective, water repelling property is strong, avoid the secondary slungshot to hurt sb.'s feelings again, little to shaking on every side, the broken tool that is applicable to mine rock second-time breakage that cost is low.
For realizing above-mentioned goal of the invention, this is novel takes following technical measures:
This novel it comprise by the main charge of charge shell suit and be provided with on the charge shell top end face can be by the round tube hole of its ignition; It is characterized in that: charge shell is a truncated conical shape, and its bottom surface is for suppressing the sockets for collecting energy of the hollow sphere shape that forms, and the main charge in it is emulsion or emulsion and the mixture that contains the energy component.
This novel feature also is: the charge shell end face is curved surface shaped or is planar shaped; Containing in the main charge can component be useless gunpowder.
This novel compared with prior art beneficial effect is as follows:
This product is its main charge of new product according to the surface mining needs: adopt emulsion or emulsion and the mixture that contains energy component (useless gunpowder) to add a setting dress and form, mainly be applicable to the secondary blasting in mine.Main feature is not contain TNT, and is pollution-free, little to shaking on every side, can alleviate working strength of workers; The performance of this product reaches the Q/HCGS121-1999 standard-required, and the product of trial production has successively advanced large batch of on probation in units such as rod milling mountain, Tangshan iron ore, Shoudu Iron and Steel Co mine company, north chestnut mineral offices, and each user is very satisfied to this product.Think this fragmentation tool: crushing effect is fine, reaches and satisfy user's requirement.Therefore this product is the substitute products that mining industry of new generation is used for secondary blasting.By the large rock mass second-time breakage is handled following characteristics are arranged:
1, this fragmentation tool crushing effect is good, because shell structure adopts sphere shape sockets for collecting energy, the result of Mohaupt effect, be that the detonation wave energy is concentrated relatively, promptly singly do not make ore deposit scar perforation, do not produce flying again, and rock, ore are produced the pressure break effect, reach the purpose of fragmentation.As 1～2m
3Bulk only get final product with the broken tool of 1 0.5kg, and breaking size is even.
2, this fragmentation tool powder charge result is simple, does not need booster gains to detonate.Safe and reliable, adopt this fragmentation tool not need manually to cut a hole the stone punching, reduced the harm of dust to the workman, Po Sui large rock mass seldom produces slungshot in addition, has avoided two quick-fried slungshots to hurt sb.'s feelings.
3, this fragmentation tool technical performance is strong, when density reaches 1.10～1.35g/m
3The time, explosion velocity is 5000～6000m/s, brisance 〉=14mm, and satisfied the requirement of second-time breakage: lumpiness is less than 1m
3
4, this fragmentation tool can be saved the secondary blasting expense, reduces mining cost, through experiment, and the broken 1m of past rod milling mountain iron ore
3Bulk uses 2
#Tnt explosive 0.75kg, and use broken tool only to use 0.5kg, obviously reduce mining cost.
Description of drawings:
Fig. 1 is this novel concrete structure figure;
Fig. 2 is the another kind of embodiment of Fig. 1.
Describe in further detail in conjunction with the embodiment of above-mentioned accompanying drawing this programme:
Referring to Fig. 1～2, this novel it comprise that the charge shell that is made of plastics 2 is truncated conical shape, its end face is curved surface shaped or planar shaped, its diameter of phi 1 is 47～80mm, diameter of phi 2 is 147～234mm, height H is 50～77mm, thickness of shell is 0.6～0.8; Be equipped with in it main blasting charge 3 adopt add in emulsions or the emulsion 30%～40% contain can component (useless gunpowder) mixture, manual then puddling evenly, shine below the medicine of a cold nature to 40 ℃, with the Stainless Steel instrument medicine is packed in the housing 2 of powder charge, and weigh up weight on request, the sockets for collecting energy 4 of the hollow sphere shape that suppresses with mould sticks the thin mould of plastics, vanning at last; Being provided with on charge shell 2 top end faces can be by the round tube hole 1 of its ignition, and available its inserts detonator.This product is placed on the rock that is applied, on round tube hole 1, insert detonator, connect lead-in wire, detonate in good time and can achieve the goal.
Claims (3)
