1) moved volume of surrounding rock
围岩移进量
2) displacement forecast of rockstrata
围岩移近量预测
3) roadway surrounding rock deformation amount
巷道围岩移近量
4) Displacement of surrounding rock
围岩位移
1.
After the excavation of powerhouse system, we monitored that the displacement of surrounding rock increases quickly and its space displacement is obvious.
厂房系统开挖后,监测到围岩位移迅速增大,空间位移表现明显,围岩位移和应力一般在支护后变化逐渐趋缓;围岩位移和锚杆应力曲线呈台阶式分布,从围岩位移变化、锚杆和锚索应力变化来看,厂房与主变室的交叉洞口处,变形较大,厂房上游拱座处受力较为复杂,变形也较大。
2.
According to the large quantity of in situ measured data,the characteristics and variation laws of displacement and load of bolts in the surrounding rock are studied,and the factors which influence the displacement of surrounding rock and the load along bolts are analyzed as well.
通过大量的原型监测数据 ,研究了大型地下洞室的位移特性、锚杆应力特性以及它们的变化规律 ,并分析了对围岩位移和锚杆应力的影响因
5) moving displacement of side-to-side and roof-to-floor in roadway
围岩移近
1.
1 mine ,the moving displacement of side-to-side and roof-to-floor in roadway is too big due to the roadway pressure and the weak coal rock, and because the traditional U bracing trellis is not effective ,thus ,the control measure of the enhancement of the bolt for the weak coal rock has been adopted to achieve good effect.
潘一矿东翼-530m--800m暗主斜井,在过C13-1煤层时,由于巷压较大、煤岩松软等原因,造成巷道围岩移近量过大,传统的U型棚支护已不能发挥作用,通过采取锚杆补强的控制措施,取得了良好效果。
6) Rock movement range
岩移范围
