Description
Изобретение относитс к области горной промышленности, а именно к разделу разработки Пластовых месторождений полезных ископаемых с выкладкой бутовой полосы в лаве вдоль штрека.The invention relates to the field of the mining industry, namely to the section of the development of the Plast mineral deposits with the laying of a rubble strip in the lava along the drift.
По предлагаемому способу взрывание пробуренного со штрека в почве разрабатываемого пласта производитс параллельно линии очистного забо скважин. При этом дл защиты штрека при взрывании этих скважин оставл ют предохранительный породный целик между боковой стенкой штрека и бутовой полосой , что обеспечивает снижение трудоемкости и ускор ет работы по возведению бутовой полосы в лаве, вдоль штрека.According to the proposed method, blasting from a drift drilled into the soil of a developed reservoir is carried out parallel to the line of the cleaning hole of the wells. At the same time, to protect the drift when blasting these wells, a safety rock pillar is left between the side wall of the drift and the rubble strip, which reduces the labor intensity and speeds up work on the construction of the rubble strip in the lava along the drift.
На чертеже изображена выкладка бутовой полосы в лаве вдоль штрека (вид в плане) и разрезы по А-А и Б-Б.The drawing shows the layout of the rubble strip in the lava along the drift (plan view) and sections along aa and bb.
Устройство содержит бутовую полосу / штрек 2, скважину 3, лаву 4, органку 5 и зашитный породный целик 6.The device contains a rubble strip / drift 2, a well 3, a lava 4, an organka 5 and a hard rock pillar 6.
Предлагаемый способ выкладки бутовой по лосы в лаве вдоль штрека может быть применен как по восстанию, так и по падению разрабатываемого пласта.The proposed method for calculating the rubble in the lava along the drift can be applied both in the uprising and in the fall of the reservoir under development.
Предмет изобретени Subject invention
Способ выкладки бутовой полосы в лаве вдоль штрека, отличающийс тем, что, с целью трудоемкости и ускорени работ, выкладку бутовой полосы производ т посредством взрывани пробуренного со штрека в почве разрабатываемого пласта параллельно линии очистного забо лавы скважин с оставлением защитного породного целика между боковой стенкой штрека и бутовой полосой.The method of laying the quarry strip in lava along the drift, characterized in that, in order to labor intensively and speed up work, the rubbish strip is laid out by blasting the developed reservoir drilled from the drift in the soil parallel to the well clearing line leaving the side wall of the drift and rubble stripe.
