对芒特泰勒(Mt.Taylor)矿高17.4米的竖井井底车场-装载硐室的变形测量是对其稳定性和安全性的持续检验。在三个不同标高的水平线上安装了测量仪表并进行监控,它们各由三条线路组成。测量数据表明,柔性支架约束住了围岩。柔性支架由岩石与衬板之间混有纯水泥的豌豆状砾石和衬板与钢圈梁之间的让压木块构成。装载硐室为椭圆形,内径长径11.6米,短径9.6米。让压木块设计压缩值为15厘米,预计最大压缩量为7厘米,实测为5.7厘米。变形测量还表明,变形值随着时间的过去和从测量站到掘进中的临时井底之间的距离的增长而逐渐减小。 Deformation measurements of the shaft-bottoms, 17.4 meters above the Mt.Taylor mines, are ongoing tests of their stability and safety. The measuring instruments are installed and monitored on the level of three different elevations, each consisting of three lines. The measurement data shows that the flexible support restrains the surrounding rock. The flexible support consists of pea gravel mixed with pure cement between the rock and the lining board and the pressure-releasing wooden block between the lining board and the steel ring beam. Loading chamber is oval, the inner diameter of 11.6 meters long, 9.6 meters short diameter. Let compression block design compression value of 15 cm, the maximum compression is expected to 7 cm, measured as 5.7 cm. Deformation measurements also show that the deformation values ​​decrease over time as the distance between the measurement station and the temporary bottom of the tunneling increases.
