Abstract
Изобретение относится к патронам для взрывания. Применяется для надежного и безопасного взрывания в качестве скважинных зарядов при взрывных работах на земной поверхности в обводненных скважинах. Предлагаемый патрон для взрывания состоит из взрывчатого материала и полиэтиленовой оболочки, у которой днище заварено и боковая поверхность на расстоянии h = 30-79% от ее днища, определенном относительно высоты Н взрывчатого материала, перфорирована, при этом патрон снабжен дополнительно тканой оболочкой с днищем, имеющей наружные или внутренние машинные швы, и тканая оболочка расположена снаружи полиэтиленовой оболочки, причем все горловины оболочек соединены вместе и прошиты внешним машинным швом или машинными швами. Перфорация у полиэтиленовой оболочки представляет собой отверстия диаметром d = 0,5-2,5 мм, выполненные в одну линию перпендикулярно оси патрона с шагом s = 5-11 мм. Высота каждой полиэтиленовой оболочки равна или превышает высоту тканой оболочки до 100 мм, а длина контура полиэтиленовой оболочки равна или превышает длину контура тканой оболочки до 48 мм в поперечном сечении патрона, причем машинные швы расположены на расстоянии b=5-55 мм от кромок патрона при расстоянии между швами В = 5-60 мм. Донная часть тканой оболочки перегнута на 180° и прошита двумя внешними машинными швами по прямой линии и одним внешним швом по вогнутой линии. Боковая поверхность тканой оболочки перегнута на 180° и прошита внешним машинным швом, при этом тканая оболочка сшита из полипропиленового мешка отечественного или импортного производства или из полипропиленового мешка из-под гранулированной аммиачной селитры или из-под тротила, причем полиэтиленовая оболочкаThe invention relates to cartridges for blasting. It is used for reliable and safe blasting as borehole charges during blasting operations on the earth's surface in flooded wells. The proposed cartridge for blasting consists of an explosive material and a polyethylene shell, in which the bottom is welded and the side surface at a distance h = 30-79% of its bottom, defined relative to the height H of the explosive material, is perforated, and the cartridge is provided with an additional woven shell with a bottom, having outer or inner machine seams, and a woven casing is located outside the polyethylene casing, with all the casing necks joined together and stitched with an external machine seam or machine seams. The perforation of the polyethylene sheath is a hole with a diameter d = 0.5-2.5 mm, made in one line perpendicular to the axis of the cartridge with a step s = 5-11 mm. The height of each polyethylene sheath is equal to or greater than the height of the woven sheath up to 100 mm, and the length of the contour of the polyethylene sheath is equal to or greater than the length of the contour of the woven shell up to 48 mm in the cross section of the cartridge, with the machine seams located at a distance of b = 5-55 mm from the edges of the cartridge the distance between the seams B = 5-60 mm. The bottom part of the woven shell is bent by 180 ° and stitched with two external machine seams in a straight line and one external seam in a concave line. The side surface of the woven shell is bent by 180 ° and stitched with an external machine seam, while the woven shell is sewn from a domestic or imported polypropylene bag or from a polypropylene bag from under granulated ammonium nitrate or from trotyl, and the polyethylene sheath
