Abstract
The invention discloses a preparation method of a porous granular ammonium nitrate fuel oil explosive. The method comprises the steps that diesel oil and fine coal powder are thoroughly mixed in proportion; porous granular ammonium nitrate and the diesel oil with the coal powder in the first step are stirred continuously till the mixture is even to obtain the ammonium nitrate fuel oil explosive. Compared with existing industrial explosives, the porous granular ammonium nitrate fuel oil explosive is simple in preparation method, less in production cost, significant in coloration effect and suitable for industrial production and is relatively complete in explosion energy release when the coal powder with the oil can be in close contact with the porous granular ammonium nitrate.
Description
Technical field
The present invention relates to industrial explosive technical field, be specifically related to a kind of production porous particulated ammonium oil explosive method.
Background technology
Ammonium nitrate-fuel oil mixture, especially porous ammonium nitrate-fuel oil mixture, because it is simple to operate, production cost is low, be widely used, ammonium nitrate-fuel oil mixture is the mixture of Oxidizing and Reducing Agents, Oxidizing and Reducing Agents exposure level is relatively low, cause its reaction not exclusively, cause blast performance relatively low, document (Atsumi Miyake, Hidefumi Kobayashi, Hiroshi Echigoya, et al. Detonation characteristics of ammonium nitrate and activated carbon mixtures [J], Journal of Loss Prevention in the Process Industries, 20 (2007) 584 – 588) have studied the blast performance of gac and ammonium nitrate, because ammonium nitrate and gac can not intimate contacts completely, so blast performance is not very desirable.
On the other hand because ammonium nitrate is ball-type, space between porous particulated ammonium oil explosive particle is comparatively large, and explosion energy loss is comparatively large, causes brisance to reduce, therefore effectively reducing porosity, is another solution improving porous ammonium nitrate-fuel oil mixture blast performance.
summary of the invention:
The present invention, in order to reduce existing porous particulated ammonium oil explosive cost, maintains simultaneously and even improves porous particulated ammonium oil explosive blast performance, propose a kind of preparation method of porous particulated ammonium oil explosive.
For achieving the above object, technical scheme of the present invention is: a kind of preparation method of porous particulated ammonium oil explosive, comprises the steps:
The first step, diesel oil to be mixed in proportion fully with fine coal powder;
Second step, constantly to stir in ammonium nitrate and the first step until stir containing the diesel oil of coal dust.
In above-mentioned steps, in described ammonium nitrate-fuel oil mixture, diesel quality is 1%-5%, and the mass ratio of fine coal powder is 1%-5%, and diesel oil and the total accounting of fine coal powder quality are 6%, and all the other are porous ammonium nitrate.
In above-mentioned steps, the particle diameter of described fine coal powder is more than 320 orders.
The invention has the advantages that: described method is simple, combine porous particulated ammonium oil explosive manufacturing condition, reduce porous particulated ammonium oil explosive production cost, reach significant coloring effect simultaneously, be suitable for suitability for industrialized production, coal dust containing oil can contact closely with ammonium nitrate, and explosion energy release is relatively complete.
Embodiment
Illustrate that the invention will be further described below by concrete example, but enforcement example does not limit the scope of the invention.
Embodiment 1
Prepare porous particulated ammonium oil explosive 5kg, ammonium nitrate: diesel oil: 320 order coal dust screen underflow=94:5.5:0.5.Diesel oil and coal dust are proportionally mixed, mix after mixing with ammonium nitrate component, with reference to porous ammonium nitrate-fuel oil mixture explosion velocity testing method test explosion velocity, novel porous ANFO explosives prill explosion velocity is 2960m/s.Common porous ANFO explosives prill explosion velocity is 2830 m/s.
Embodiment 2
Prepare porous particulated ammonium oil explosive 10kg, ammonium nitrate: diesel oil: 320 order coal dust screen underflow=94:3:3.Diesel oil and coal dust are proportionally mixed, mix after mixing with ammonium nitrate component, with reference to porous ammonium nitrate-fuel oil mixture explosion velocity testing method test explosion velocity, novel porous ANFO explosives prill explosion velocity is 2890m/s.Common porous ANFO explosives prill explosion velocity is 2830 m/s.
According to the existing price of existing market, after using fine coal powder, porous particulated ammonium oil explosive is per ton can save cost 150-200 unit.
