摘要
通过对废弃老采空区分析,将老采空区分为三种不同类型区:(1)由最大下沉值组成的竖向压缩区;(2)由下沉拐点到最大下沉点组成的不稳定区;(3)由边界点到下沉拐点组成的半稳定区。并对其残余沉降空间进行了分析。根据老采空区特点,提出了残余移动变形等效采厚的概率积分预测方法,对老采空区残余沉降预测方法研究起到推动作用。
By analyzing abandoned mine goaf, it comprises three type area: vertical compressed area among maximum subsidence, instable area between maximum and inflexion, semi-stable area between boundary and inflexion. And each of them is analyzed. On base of peculiarity of abandoned mine goaf, probability integral method of equivalent mining thickness is put forward to prediction residual movement and deformation of abandoned mine goaf, it has great effect on prediction method of residual movement and deformation of abandoned mine goaf.
