Description
Изобретение относитс к горнодобывающей промышленности и может быть использовано при поддержании горных выработок в услови х пучащих пород почвы.The invention relates to the mining industry and can be used in the maintenance of mine workings in the conditions of puffing soil rocks.
Цель изобретени - снижение затрат на поддержание выработки.The purpose of the invention is to reduce the cost of maintaining production.
На фиг. 1 показано формирование ленточных барьерных целиков при горизонтальном расположении сло пучащих пород; на фиг. 2 - формирование целика нри наклонном залегании сло пучащих пород.FIG. Figure 1 shows the formation of tape barrier pillars with a horizontal arrangement of a layer of pulling rocks; in fig. 2 - formation of the pillar in the oblique bedding of the straying rocks.
По направлению к слою пучащих пород 1 бур т щпуры 2 и взрыванием в них камуфлет- ных зар дов образуют зону трещиноватос- ти, в которую нагнетают в жущий раствор. В результате образуют барьерный целик 3Towards the layer of pulling rocks 1, the drill bit 2 and the blasting of camouflage charges in them form a fracture zone, into which they are injected into the mortar. As a result, form a barrier pillar 3
