Description
В известных способах отбойки полезных ископаемых при помощи зар дов ВВ (взрывчатых веществ) щпуры и патроны этих зар дов имеют цилиндрическую форму.In the known methods of blasting minerals using explosive charges (explosives), the drill bits and the cartridges of these charges are cylindrical in shape.
Отличительной особенностью описываемого способа вл етс применение ПЛОСких пр моугольной формы щпуров в сочетании с плоскими пр моугольными зар дами ВВ. Это обеспечивает снижение выхода щтыба и более раЕ омерное дробление полезного ископаемого.A distinctive feature of the described method is the use of flat rectangular nipples in combination with flat rectangular explosive charges. This ensures a reduction in the yield of shtyb and more uneven crushing of the mineral.
На фиг. 1 схематически изображен один из вариантов расположени плоских пр моугольных шпуров в очистном забое; на фиг. 2 - один из вариантов расположени пр моугольных щпуров в забое подготовительной выработки.FIG. Figure 1 shows schematically one of the options for the location of flat rectangular boreholes in the longwall; in fig. 2 is one of the options for the arrangement of rectangular dowels in the bottom of the preparatory development.
Дл ведени буровзрывных работ по -олисываемому способу в очистном или подготовительном забое полезного ископаемого при помощи пневматической «ли электрической цепной пилы нарезаютс тонкие пр моугольные щпуры в соответствии с разработанным паспортом. Затем щпуры зар жаютс плоскими пр моугольной формы зар дами ВВ и производитс взрывание.In order to conduct drilling and blasting operations in a selective manner, in cleaning or preparatory mining of a mineral by means of a pneumatic electric chain saw, thin rectangular drill bits are cut in accordance with the developed passport. Then the drills are charged with flat rectangular explosive charges and exploded.
Предмет изобретени Subject invention
Способ отбойки полеаных ископаемых посредством зар дов ВВ, о тл-и чающийс тем, что, с целью снижени выхода щтыба и обеспечени равномерного дроблени , отбойку осуществл ют пр моугольной формы зар дами взрывчатых веществ, размещаемыми в щпурах соответствующей формы.The method of blasting the minerals by means of explosive charges, which is only so that, in order to reduce the yield of the pier and to ensure uniform crushing, the blasting is carried out rectangular in form of explosives placed in the cores of the corresponding form.
