[地质] adjoining rock stability
- 初始地应力是地下工程围岩稳定与支护结构设计的一个基本参数。
In situ stress is one of the basic parameters for the stability of surrounding rock and the design of support structure. - 井下试验表明,高预应力、强力锚杆支护系统能有效控制深部巷道强烈变形,保持围岩稳定。
Underground test showed that this system can control large do formation of deep mine to keep stability of its surrounding cock. - 这为研究煤炭地下气化时热作用下燃空区的围岩稳定及应力场和位移场的变化规律提供试验依据。
The results provide experimental basis for stability of surrounding rock when heat exits in the place of firing and variation regularity of strain field and displacement field.
