坑内开采引起的上覆岩层移动速度,从宏观上考虑,当其低于某临界值时便视为岩移终止,到达该临界值后岩移还会以较小的速度持续一段时期,这一阶段称为岩移终止期。将岩移处于终止期作为判断采区上部井巷、建筑及山体不再发生危险性变形或移动的依据。随着对岩层移动规律及建筑物结构研究的逐步深入,岩移范围内的建筑在一定条件下可以继续
Considering macroscopically, the moving speed of overburden caused by pit mining is regarded as the termination of rock movement when it is below a certain critical value. After the critical value is reached, rock movement will continue for a period of time at a relatively low speed The stage is called Rock Removal Termination. The rock movement at the termination of the mine as the upper part of the decision to determine the upper lane, building and mountain no longer dangerous deformation or movement of the basis. With the gradual deepening of the research on the law of rock movement and the study of building structure, the building within the range of rock migration can continue under certain conditions
