Abstract
Изобретение относитс к горнодобывающей промышленности и предназначено дл креплени горных выработок. Цель - повышение эксплуатационной надежности анкерной крепи. Анкер включает стальной стержень 1 с закрепленной на нем шайбой 2, уплотнительной шайбой 6 и нат жной гайкой 5. На стержне 1 размещен обсадной стакан 7 с продольными щел ми 8 и упором 9. Стержень 1 расположен в сыпучем материале (СМ) 3, снабженном хаотично ориентированными в его объеме фибрами 4. Фибры 4 выполнены в виде отрезков тонкой стальной проволоки. Уплотнительна шайба 6 вдавливаетс внутрь обсадного стакана 7. При этом происходит уплотнение СМ 3 с фибрами 4 и расклинивание обсадного стакана 7 за счет продольных щелей 8. Стержень 1 по всей длине взаимодействует с массивом горных пород посредством фибр 4 в СМ 3 и обеспечивает надежное противодействие деформированному процессу в окрестности выработки. 1 ил.The invention relates to the mining industry and is intended to fasten mine workings. The goal is to increase the operational reliability of anchor lining. The anchor includes a steel rod 1 with a washer 2 fixed on it, a sealing washer 6 and a tension nut 5. On the rod 1 there is a casing 7 with longitudinal slots 8 and an anvil 9. The rod 1 is located in a loose material fibers oriented in its volume 4. The fibers 4 are made in the form of thin steel wire segments. The sealing washer 6 is pressed into the casing 7. This seals the CM 3 with fibers 4 and wedges the casing glass 7 due to the longitudinal slits 8. The rod 1 along the entire length interacts with the rock mass by means of fibers 4 in the CM 3 and provides reliable resistance to the deformed process in the vicinity of development. 1 il.
