Description
Granulated emulsion explosive for rocks belongs to the explosive class.It mainly is is the ammonium nitrate-fuel oil mixture of oxygenant preparation with the ammonium nitrate and makes the explosive mixture that adhesion agent is formed with emulsion explosive.
In underground mine, in the long-hole blasting project, replace in the big gun hole, loading powder type explosive by hand with the pneumatic loading device.Because explosive does not have viscosity, the air-flow of pneumatic loading device can be produced by boasting about 15% explosive in the big gun hole.Not only dust from flying pollutes working face, has a strong impact on the healthy of workman, and has increased the cost of blasting operation.The emulsion explosive of applying at present is paste, because viscosity is too big, is unsuitable for the powder charge in the big gun hole of pneumatic loading device.The titania-mica of abroad applying (claiming the latex ammonium nitrate-fuel oil mixture again) is the mixture that emulsoid and ammonium nitrate-fuel oil mixture are formed.Its emulsoid is that the main components such as high-temperature water solution, oil, wax, emulsifying agent of main composite oxidant salt are formed by ammonium nitrate.The BME series granular emulsion explosive of China Beijing Mine and Metallurgy General Inst development (seeing " the academic proceeding of whole nation mining for the second time ", in December, 198 6), similar to external titania-mica.These two kinds of explosives lose with the pneumatic loading device and load in the big gun hole.And be non-detonator sensitivity, need detonate with priming explosive.The viscous granular Non-TNT explosive (seeing Chinese patent CN85100393A) of Changsha Mine Inst's development has viscosity, available charge pneumatic machinery.The main component of this explosive is, 76～90% ammonium nitrate, and 8～20% thickness sensitizing agent, surplus are diesel oil.The thickness sensitizing agent is the methylamine nitrate by 85-92%, and the polyacrylamide of 8-15% is formed.This explosive processing is simple, and production cost is lower, and transportation and use are safer.But the blast performance to this explosive in the CN85100393A specification sheets is not described.
The objective of the invention is to develop a kind of can underground mine adopt the pneumatic loading device in, the explosive of deep blasting hole filling.Requirement to this explosive is that the pneumatic loading device can blow and draw, and can glue to such an extent that live in the big gun hole, and have a water resisting property and good blast performance, satisfies need of explosion engineering.
The granulated emulsion explosive for rocks that the present invention proposes is to be puddled by ammonium nitrate-fuel oil mixture and emulsion explosive to form, and its preparation process is as follows:
The preparation of emulsion explosive: ammonium nitrate, SODIUMNITRATE, urea, sodium lauryl sulphate etc. are soluble in water, or do not add SODIUMNITRATE and urea preparation aqueous phase solution.With compound wax, diesel oil, emulsifying agent such as heat fused such as sorbitan list olein, additive rosin as oil phase, under condition of stirring, aqueous phase solution is injected in the oil phase, carry out emulsifying effect, make the w/o type water-in-oil emulsion, add whipping agent such as Sodium Nitrite and sensitive agent aluminium powder again, or do not add aluminium powder, promptly make emulsion explosive.The composition of emulsion explosive following (weight, %):
Ammonium nitrate 63-83
SODIUMNITRATE 8-14(or do not add)
Urea 1-3(or do not add)
Water 9-12
Emulsifying agent sorbitan list olein 1.5-2.0
Compound wax 1.5-2.0
Diesel oil 1.0-2.0
Aluminium powder 0.3-2.0 (or not adding)
Sodium lauryl sulphate 0.24-0.4
Whipping agent Sodium Nitrite 0.20-0.25
Additive rosin 1.5-4.0
The preparation of ammonium nitrate-fuel oil mixture: permeate ammonium nitrate, powdery ammonium nitrate, aluminium powder with diesel oil, mixtures such as additive rosin perhaps do not add powdery ammonium nitrate, aluminium powder.The mixture that has permeated diesel oil is stirred, promptly make ammonium nitrate-fuel oil mixture.Its composition following (weight, %):
Ammonium nitrate 67-95
Diesel oil 3-6
Ammonium nitrate (powdery) 20-25 (or not adding)
Aluminium powder 2.0 (or not adding)
Additive rosin 1-5
Above-mentioned two kinds of explosives that prepared are mixed, stir, promptly make granulated emulsion explosive for rocks.Its emulsion explosive consumption is a 10-50%(weight), ammonium nitrate-fuel oil mixture is 50-90%.
The present invention is owing to adopt above-mentioned raw materials proportioning (gross weight of forming every kind of explosive is 100%) and preparation method, and the granulated emulsion explosive for rocks of making has certain form.When the preparation emulsion explosive, do not add SULPHUR POWDER, can not produce SO behind this explosive charge
2And H
2Obnoxious flavoures such as S.General emulsion explosive all will be put into Auto-regulating System of Density of Heavy Medium with emulsoid in preparation process indoor, under 50 ℃ of temperature, through foaming in 5-7 hour, can guarantee that just emulsion explosive has good blast performance.This quick-fried medicine can foam at normal temperatures voluntarily, can save foamed process.This explosive is raw materials used, and sale is all arranged on market.Direct production cost is all lower than No. 2 rock explosives that use now and emulsion explosive, only 780-930 unit/ton.General emulsion explosive production factory need not increase investment this explosive of just can changing the line of production.
The granulated emulsion explosive for rocks that the present invention proposes has detonator direct initiation sensitivity No. 8.Be packaged into the powder stick of diameter 43mm with paraffin paper paper shell, preserve and still can detonate fully in one month, do not have residual medicine.Brisance under the steel tube confinement condition is more than 30mm.At internal diameter is under the steel tube confinement of 50mm, and explosion velocity is greater than 3000 meter per seconds.With the powder charge of pneumatic loading device, this explosive blows and draws, and sticking as to live in the big gun hole, charge density is a 1.22-1.30 gram/cubic centimetre.Returning dose lacks than No. 2 rock explosives.This explosive all compares safety in use, transportation, preservation process.
The invention will be further described with embodiment below.
Example 1. is with 81.5%(weight) ammonium nitrate be dissolved in 10% the hot water, water temperature is 95 ℃-105 ℃, adds 0.26% sodium lauryl sulphate again, makes aqueous phase solution.Compound wax with 1.5%, 1% diesel oil and 1.5% additive rosin are heated to 95 ℃, make oil phase, add emulsifying agent sorbitan list olein 2% again.Aqueous phase solution is injected oil phase, make w/o type milk sap.In the time of 50-60 ℃, add whipping agent Sodium Nitrite 0.24% and sensitive agent aluminium powder 2%, promptly make emulsion explosive.
Ammonium nitrate with 76%, 15% powdery ammonium nitrate and 4% rosin mix, and the diesel oil infiltration with 5% is more than 3 hours, puddles even ammonium nitrate-fuel oil mixture.
Select the emulsion explosive adhesion agent of 10-50% as required, its surplus is an ammonium nitrate-fuel oil mixture, with both puddle evenly granulated emulsion explosive for rocks.
Example 2 is dissolved in 65.5% ammonium nitrate, 14% SODIUMNITRATE, 2% urea in 10% the water (95-105 ℃), adds 0.26% sodium lauryl sulphate again, makes the oxygenant aqueous phase solution.Compound wax with 1.5%, 1.5% diesel oil, 2% emulsifying agent sorbitan list olein, 2.74% additive rosin is heated to 95 ℃, makes oil phase.Aqueous phase solution is injected oil phase, make w/o type milk sap.The whipping agent Sodium Nitrite of adding 0.5% is promptly made emulsion explosive under 50-60 ℃.
The preparation of ammonium nitrate-fuel oil mixture and granulated emulsion explosive for rocks is with example 1.
Example 3-9, the preparation method is with top described, and its prescription is listed in table 1, table 2.
