| 摘 要： | 为了对长壁垮落法开采老采空区"活化"引起的地表残余沉降进行估计,从老采空区的覆岩形态结构出发,提出把长壁垮落法开采老采空区分成2个区进行预计:边界的欠压密区和中部的压密区,给出了欠压密区和压密区的尺寸.针对边界"活化"空间的分布特征和突发性"活化"特点,提出等价成变采高的小工作面开采来预计边界"活化"引起的地表残余沉降...

| Abstract: | To estimate surface residual settlement caused by activation of old goaf with longwall caving,we propose,for the first time,that the old goaf is divided into two areas based on the morphological structure of overlying strata.These two areas are: 1) the border brown-dense area,and 2) the central compaction zone.In addition,we have given the size of brown-dense area and the compaction zone.Aiming at the spatial distribution characteristics of border activation and the sudden happening of border activation,we ... |
