为了不占或少占农田,广西长营岭选矿厂的厂址选在灰岩的山坡上。选厂的粗重选工段厂房均座落在标高234～315米的边坡台阶上。通过设计方案的选择和岩石边坡稳定计算,这项工程的施工中采用了喷锚加固岩石边坡、柱基岩石边坡而取代了钢筋混凝土护壁的新技术。该工程自1977年8月份开始施工,至年底土建工程基本结束,共采用喷锚加固柱基下及墙基下岩
In order not to occupy or occupy less farmland, the site of Guangxi Changyingling Concentrator is selected on the limestone hillside. Heavy factory electoral plant sections are located in the elevation of 234 to 315 meters on the slope of the steps. Through the selection of design scheme and the stability calculation of rock slope, the new technology of sprayed anchor to reinforce rock slope and plinth rock slope instead of reinforced concrete retaining wall was adopted in the construction of this project. The project started construction in August 1977 and by the end of civil engineering basically ended, the use of spray anchor reinforcement column foundation and rock under the rock
