Abstract
The present invention is a kind of one-level, secondary emulsion explosive for coal mine novel method that the down-hole coal excavation explosion is used of producing.
At present, produce emulsion explosive both at home and abroad and all adopt SODIUMNITRATE to make oxygenant, the present invention adopts industrial table salt---and sodium-chlor replaces SODIUMNITRATE.
Advantage of the present invention is: replace price height and market SODIUMNITRATE in short supply with the competent sodium-chlor in the source of cheapness, not only reduced the explosive cost, solved raw material sources, simultaneously, sodium-chlor still has the flame arrest effect that suppresses blow-up.Be solid-state oil phase material owing to adopt under the normal temperature, the stability in storage of this explosive is good, and kenel is stronger than other emulsion explosive, is convenient to use under the coal mine.This explosive is with the sausage stuffer can of paraffin paper tube, the also vertical charge machine powder charge of available powdery ammonium ladder detonator, and charge device is simple, and explosive load is accurate.
Description
The present invention is a kind of one-level, secondary emulsion explosive for coal mine novel method that the down-hole coal excavation explosion is used of producing.
The emulsion explosive of producing both at home and abroad all adopts SODIUMNITRATE to make oxygenant at present.On November 20th, 1987, Hebei province institute of scientific-technical information uses the DIALOG international on-line retrieval system, the thematic information retrieval, search the relevant data storehouse, the result is: 1963～1980, the 1981～present emulsion explosive of making oxygenant without SODIUMNITRATE of all not finding of World Patent Index.At present, SODIUMNITRATE is in short supply and price is high on market, and raw material sources can't guarantee.
Make oxygenant for solving without SODIUMNITRATE, guarantee the performance of explosive again,, develop a kind of novel method that replaces SODIUMNITRATE production emulsion explosive for coal mine with industrial table salt-sodium-chlor finally through experiment in a large number.
Content of the present invention is: replace SODIUMNITRATE with sodium-chlor, with sodium-chlor, ammonium nitrate, urea and tensio-active agent 6503 is water-phase material, with paraffin, Vaseline, stearic acid, pitch and mineral oil is oil phase material, with SPan-80 is emulsifying agent, is that whipping agent is made emulsion explosive for coal mine with Sodium Nitrite and ammonium nitrate.
The set of dispense ratio of one-level emulsion explosive for coal mine is:
Ammonium nitrate 70.0～73.6%;
Sodium-chlor 9.0%～8.0%;
Urea 2.5～0.5%;
Water 12.0～10.0%;
6503 0.1～0.2%;
Paraffin 0.3～1.0%;
Pitch 0.5～1.0%;
Vaseline 0.5～1.0%;
Mineral oil 3.5～2.5%;
SPan-80 1.5～2.0%;
Sodium Nitrite 0.1～0.2%;
The set of dispense ratio of secondary emulsion explosive for coal mine:
Ammonium nitrate 68.5～72.1%;
Sodium-chlor 11.0～10.0%;
Urea 2.5～0.5%;
Water 12.0～10.0%;
6503 0.1～0.2%;
Paraffin 0.3～1.0%;
Pitch 0.5～1.0%;
Vaseline 0.5～1.0%;
Mineral oil 3.0～2.0%;
SPan-80 1.5～2.0%;
Sodium Nitrite 0.1～0.2%.
The present invention is achieved in that
One, water fusing: water-phase materials such as load weighted water, ammonium nitrate, sodium-chlor, urea and 6503 are dropped into water successively dissolve in the jar, heated and stirred is to dissolving, and temperature is controlled at 110～120 ℃.
Two, oil phase fusing: will heat in load weighted paraffin, pitch, Vaseline, the mineral wet goods oil phase material input oil phase melting tank, temperature is controlled at 100～130 ℃, must not surpass 130 ℃, be stirred to whole fusings.
Three, emulsification: will dissolve good oil phase material and add emulsifying agent SPan-80, stir and import in the emulsor after 2～3 minutes, stir with the rotating speed that is not less than 1000 rev/mins, and then will melt good water-phase material and slowly inject, treat that water-phase material all annotated back continuation stirring 5 minutes.
Four, cooling: the emulsoid that emulsification is good is put into water cooler, is cooled to 55～65 ℃.
Five, sensitization: the emulsoid that will be cooled to 55～65 ℃ places the sensitization machine, stirs with 600～800 rev/mins rotating speeds, drops into load weighted Sodium Nitrite, ammonium nitrate foaming agent solution, continues to stir 2～4 minutes.
Six, powder charge packing: will be vertical powdery ammonium ladder detonator charge machine or the sausage stuffer paraffin paper wound packages medicine that the emulsion explosive utilization is reequiped a little through the emulsification of sensitization.The powder stick diameter is 32mm or 35mm.Powder-charge temperature is 40～50 ℃.
The present invention has not only reduced the explosive cost, has solved raw material sources because of replaced the SODIUMNITRATE of shortage on price height and the market with cheap and the competent sodium-chlor of originating, and simultaneously, sodium-chlor still has the flame arrest effect that suppresses blow-up.Every performance of this explosive all meets or exceeds the performance of similar other products.Be solid-state oil phase material owing to adopt under the normal temperature, the stability in storage of this explosive is good, and kenel is stronger than other emulsion explosive, is convenient to use under the coal mine.
This explosive is with the sausage stuffer can of paraffin paper tube, the also vertical charge machine powder charge of available powdery ammonium ladder detonator, and charge device is simple, and explosive load is accurate.
