我队于1982年7月承担了姑山铁矿一条长314米的斜井施工任务。斜井倾角22°,断面为2.6×2.35米,顶板有淋水,井筒悬吊设备较多,三班作业。掘进施工中,一般给腰线比较困难,受经纬仪焦距所限;倾角超过8°,水准仪也用不上。因此,用过去井下常规给腰线方法如倾角法、靠帮平移法等都不适应。我队测量组 In July 1982, our team undertook the construction of an inclined shaft of 314m in Gushan Iron Mine. Oblique tilt angle of 22 °, section of 2.6 × 2.35 meters, roof water, well-suspension equipment more, three shifts. Driving construction, the general to the waist line is more difficult, subject to the theodolite focal length limit; dip more than 8 °, the level does not have access. Therefore, the conventional downhole method used in the past, such as dip angle method, by the translation method are not adapted. My team measured group
