Abstract
The invention discloses a porous granular ammonium nitrate fuel oil explosive safe to use based on up-hole blasting. The porous granular ammonium nitrate fuel oil explosive is prepared by mixing the following raw materials in percentage by weight: 90 to 95 percent of porous granular ammonium nitrate, 2 to 5 percent of diesel oil number 0, 2 to 5 percent of additive and 0.5 to 2 percent of sensitizing agent, wherein the additive is a mixture of one or several of ethylene-propylene rubber, vaseline, polyisobutene, A wax and epoxy resin according to arbitrary proportion. The porous granular ammonium nitrate fuel oil explosive provided by the invention not only can solve the difficult problem that an explosive is easy to return after up-hole blast charge, but also has excellent explosive property, the explosive velocity can reach 3200 to 3400m/s, and meanwhile, the production of the explosive is safer and more environmentally friendly.
Description
Technical field
The invention belongs to industrial explosive technical field, relate to a kind of ammonium nitrate-fuel oil mixture.Ammonium nitrate-fuel oil mixture of the present invention is mainly used in the explosion of perform hole.
Background technology
Also exist in upper perform hole explosion powder charge labour intensity high, return the problems such as dose is large, blast hole utilizing factor is low, and the upper perform hole blast explosive of part contains TNT, produces a large amount of toxic gas harm fireman person healthy in blasting process.
In order to solve the problem, US5454869 discloses one " ANSWAX " explosive, although this explosive solves the problem that medicine is not returned in perform hole powder charge, explosive property decreases.Diameter 75mm without confined charge, ANFO has the explosion velocity of 1800m/s, and ANSWAX puts out quick-fried; Diameter 100mm without confined charge, the explosion velocity of ANFO is that the explosion velocity of 3000m/s, ANSWAX but reduces to 2700m/s.
CN102718615A discloses a kind of ammonium nitrate-fuel oil mixture, and what it adopted solves the high problem of upper perform hole powder charge propellant return rate without terraced viscous explosive formula and preparation method, and ammonium nitrate-fuel oil mixture can be sticked in upper perform hole, explosive property is also better.But its main thought uses nontoxic methylamine nitrate to carry out the larger TNT of alternative toxicity as sensitizing agent, methylamine nitrate is a kind of single chmical compound explosive, extremely responsive, production process is complicated, process control needs is high, do not meet that on-site mixed explosive susceptibility is low, the simple requirement of production technique, there is great potential safety hazard in process of production.
CN104045495A discloses a kind of viscosity ANFO explosives prill and preparation method thereof, by adding emulsion matrix or waste emulsion explosive in ammonium nitrate, solve the problem of perform hole powder charge height propellant return rate, can be bonded in perform hole, also solve the process problem of waste emulsion explosive, performance is also better simultaneously.But the quality of waste emulsion explosive own is unstable, so puddle ammonium nitrate making viscosity ammonium nitrate-fuel oil mixture easily cause unstable product quality, and there is potential safety hazard when puddling in actual production.
Summary of the invention
The object of this invention is to provide a kind of porous particulated ammonium oil explosive based on upper perform hole explosion of use safety, to solve the problem that in upper perform hole explosion, propellant return rate is high.
Porous particulated ammonium oil explosive of the present invention is become by the mixed raw material of following weight percent: ammonium nitrate 90 ~ 95%, 0
#diesel oil 2 ~ 5%, additive 2 ~ 5%, sensitizing agent 0.5 ~ 2%.
Wherein, described additive is the arbitrary proportion mixture of one or more in second third glue, Vaseline, polyisobutene, A wax, epoxy resin.
Further, the sensitizing agent described in the present invention is glass microsphere and/or perlite.
The preparation method of porous particulated ammonium oil explosive of the present invention is according to described weight percent, and ammonium nitrate is added 0
#mix in diesel oil, the sensitizing agent adding 1/3 ~ 2/3 weight mixes, then the additive adding fusing is mixed, finally add residue 1/3 ~ 2/3 weight sensitizing agent mix.
Wherein, be that described additive is melted at 100 DEG C.
Sensitizing agent is divided into two portions by the present invention, respectively adds a part respectively in the front and back adding additive.Preferably, sensitizing agent is divided into two portions by the present invention, respectively adds the sensitizing agent of 1/2 weight at every turn.
Porous particulated ammonium oil explosive prepared by the present invention is suitable for using as upper perform hole blasting explosive.
Porous particulated ammonium oil explosive of the present invention easily returns a difficult problem for medicine after solving perform hole blasting charge, not only be applied to perform hole powder charge propellant return rate low, and there is good blast performance, explosion velocity can reach 3200 ~ 3400m/s after tested, is better than the explosion velocity of ordinary granular ammonium nitrate-fuel oil mixture 2800 ~ 3000m/s.
The present invention adds sensitizing agent at twice in the production process of porous particulated ammonium oil explosive, has both added the free-running property of explosive, and what also make sensitizing agent mix with explosive is more even, make the blast of explosive more completely, performance is improved.
Add without the single chmical compound explosive such as TNT, methylamine nitrate in porous particulated ammonium oil explosive component of the present invention, produce safer, environmental protection, raw material sources are extensive, are easy to realize industrialization and produce.
