Ktwoaiin d-ig«7 iflo egz. A-i Cena 45 il PLThe subject of the invention is an ammonium nitrate mining explosive with a high resistance to the action of water and a high degree of safety against methane and coal dust, intended for use in dry and water-laden coal seams of methane coal. mixtures of mainly ammonium nitrate in the amount of 40-80% by weight, nitroglycerin or its mixtures with ethylene glycol in the amount of 2-10% are highly safe against methane and coal dust. by weight, 0.3-9% by weight of dinitrotoluene and / or TNT, 0.3-9% by weight of wood flour or wood flour at 0.3-5% by weight, and 8-40% by weight of sodium chloride. Such non-hazardous explosives are, however, characterized by non-resistance to the action of water, which makes it impossible to carry out blasting works in wet seams of methane coal, y '' The aim of the invention is to develop a new ammonium carbonate explosive, which, while maintaining a high degree of safety against methane and coal dust, would simultaneously ensure resistance of this material to the action of water. The above requirements are met by the mining explosive according to the invention, consisting of the basic components: ammonium nitrate in the amount of 40-80% by weight, nitro-glycerin or its mixture with nitroglycol in an amount of 2-10% by weight, diitrotoluene and / or tritium in the amount of 0.3-9% by weight, wood flour or wood flour in the amount of 0.3-5% by weight and sodium chloride in the amount of 8-40% by weight, and additionally with the addition of solid coating ingredients in the form of calcium stearate and / or stearin and or paraffin in the amount of 0.1-10% by weight and guar gum (C6H10O5) and / or other substances gelling, most preferably starch, gelatin or carboxyimethylcellulose in an amount of 0.1-5% by weight. Surprisingly, it turned out that the mining explosive with the composition according to the invention is characterized by a high degree of water resistance, withstanding the action of water for at least one hour. Moreover, this material is safe against methane and coal dust, showing correct shooting properties and a low content of toxic components in the blasting gases. Example: 65% by weight of ammonium nitrate previously prepared in the measuring vessels is poured into the mixer. passing at least 90% through a sieve with a mesh opening of 0.30 mm, 3.5% by weight of wood or clove dust, 21% by weight of sodium chloride passing 100% through a sieve with a mesh opening of 1.0 mm, at least 90% through a sieve with a mesh of 0.75 mm and about 30% through a sieve with a mesh of 106 6773 106 677 4 0.20 mm, 1% by weight of calcium stearate, stearin and paraffin. The mixture is stirred for about 5 minutes, and then 1% by weight of mypradex, that is, acidic guar (CeH10O5) n, 5% by weight of nitroglycerin, and 2 to 5% by weight of dinitrotoluene and TNT, are added. The entirety is mixed again for about 10 minutes and the resulting explosive is charged into cartridges with a diameter of 36 mm and weights of 100, 150 and 200 g.
