十年来,我矿用喷锚支护了平巷、马头门、电耙巷道、竖井共八千多米;支护了盲井卷扬机房、水泵房、配电所、机修库、炸药库等八个硐室,面积共达1500多平方米。改善了支护质量,加快了施工速度,减轻了劳动强度,还节省木材850多立方米,降低支护费用42万多元。实践证明,喷锚支护是一种多快好省的支护技术。
In the past ten years, mine mines have used jet anchors to support more than 8,000 meters of roadways, horse heads, electric roadways, and shafts; they have supported blind-hole hoisting machine rooms, pump rooms, power distribution stations, machine repair libraries, and explosive magazines. Eight bedrooms, covering a total area of more than 1,500 square meters. Improve the quality of support, speed up the construction speed, reduce labor intensity, but also save more than 850 cubic meters of wood, reduce support costs more than 420,000 yuan. Practice has proved that spray-anchor support is a kind of fast and good support technology.
