Abstract
The present invention relates to an explosive, in particular it is a non-TNT and water-resistant ammonium nitrate compound explosive for coal mine, containing ammonium nitrate, edible salt, wood flour, also containing rosin, paraffin wax, diesel oil, and their weight ratio is 80.1-82% of ammonium nitrate, 5.1-6% of wood flour, 10-13% of edible salt, 0.9-2% of rosin, 0.4-1% of paraffin wax and 0.5-2% of diesel oil. Said invention doesn't contain toxic material TNT, and has the humidity resistance and water resistance, and its explosion effect is more than that of No.3 ammonium nitrate-TNT explosive for mining.
Description
The present invention relates to explosive, particularly do not have tritonal and water resisting colliery ammoniumnitrate explosives.
Existing coal mining explosive adopts anti-water an-tnt explosive more, and as No. 3 colliery an-tnt explosives, it constitutes component and proportioning is ammonium nitrate 65.5～68.5%, tritonal 9.5～10.5%, wood powder 2.1～3.1%, salt 19～21%.Wherein tritonal is toxic substance, in explosion, and the serious harm HUMAN HEALTH, moreover it is in short supply to make the raw material of toluene, concentrated nitric acid of tritonal, national departments concerned is indication expressly, stops to supply with civil explosive and produces required tritonal.
Given this, purpose of the present invention just is to provide a kind of water-proof explosive without TNT for coal mine that tritonal and blast performance are higher than No. 3 colliery an-tnt explosives that do not contain.
Water-proof explosive without TNT for coal mine of the present invention comprises ammonium nitrate, salt, wood powder, also includes rosin, paraffin, diesel oil, and its weight proportion is,
Ammonium nitrate 80.1～82%
Wood powder 5.1～6%
Salt 10～13%
Rosin 0.9～2%
Paraffin 0.4～1%
Diesel oil 0.5～2%
Above-mentioned ammonium nitrate as explosive oxidizer, mainly plays the blast effect, and ammonium nitrate content is high more, and its explosive power is strong more, increases ammonium nitrate content, thereby substitutes tritonal.Ammonium nitrate is preferably powdery.
Above-mentioned wood powder mainly plays the moment detonative action, and wood powder content is high more, and its explosive brisance is high more.Wood powder can be selected wood charcoal powder, tree bark powder etc. for use.
Above-mentioned salt as smoke suppressor and stablizer, is eliminated blast fumes, and the stable detonation performance improves security.
Above-mentioned rosin, paraffin, diesel oil as anti-water, are wrapped in outside the ammonium nitrate powder, prevent that explosive from making moist and reduce and even lose blast performance.
The present invention is with ammonium nitrate powder and wood powder, salt, diesel oil, molten rosin and paraffin uniform mixing and heat frying, and the cooling of sieving is made.
Water-proof explosive without TNT for coal mine of the present invention has following advantage and effect.
One, the present invention does not contain toxic substance tritonal, has eliminated harm blasting explosive mfr and the healthy root of user, helps environment protection.
Two, rosin of the present invention, paraffin, diesel oil can prevent effectively that explosive from making moist, and keep the blast performance of explosive.
Three, the present invention increases ammonium nitrate and wood powder content, has replaced nuisance tritonal, and blast performance is higher than the colliery an-tnt explosive No. 3.
Below, the invention will be further described to use embodiment again.
Embodiment 1
A kind of water-proof explosive without TNT for coal mine of the present invention, its component and weight proportion thereof are:
Ammonium nitrate 81.5%
Wood powder 5.5%
Salt 10.5%
Rosin 1%
Paraffin 0.5%
Diesel oil 1%
With ammonium nitrate through primary crusher, the firsts and seconds fine crusher, pneumatic drier is made dried powder; Wood powder is through the pneumatic drier drying; Rosin, paraffin melt through the air-flow melting tank; Salt is through the reverberatory furnace roasting; Measure by said ratio with diesel oil, mix after wheel roller rolls evenly, sieve the cooling of sieving through the 80 order medicine of a cold natures again, packing is made.
Embodiment 2
A kind of water-proof explosive without TNT for coal mine of the present utility model, its component and weight proportion thereof are:
Ammonium nitrate 80.1%
Wood powder 6%
Salt 10%
Rosin 1.3%
Paraffin 0.8%
Diesel oil 1.8%
The complete processing of present embodiment and embodiment 1 are similar.
Embodiment 3
Ammonium nitrate 82%
Wood powder 5.1%
Salt 11%
Rosin 0.9%
Paraffin 0.5%
Diesel oil 0.5%
The complete processing of present embodiment and embodiment 1 are similar.
The foregoing description is its blast performance after testing, compares with No. 3 colliery an-tnt explosive national standards, and the example table is as follows:
| Gap distance (cm) | Explosion velocity (m/s) | Brisance (mm) | Capacity for work (ml) | Along gas security (frequency of igniting) | Toxic gas (l/kg) | |
| No. 3 colliery an-tnt explosive GB12437-90 | ≥2 | ≥2600 | ≥10 | ≥240 | 0/5 or 0/15 | ≯80 |
| The embodiment of the invention | 6 | 2817 | 13.0 | 260 | 0/5 | 55 |
