摘要: 基于采场覆岩“垮落—断裂—弯曲下沉—地表沉陷”一体化过程,研究了岩层破坏与移动特征。根据裂隙带内岩层裂隙发育程度的不同而导致的岩层移动差异,将裂隙带划分为块体铰接带似和连续带,提出了采空区上覆岩层的“冒落带、块体铰接带、似连续带和弯曲下沉带”的“四带”划分,采用顶板铰接结构的形成条件、岩体稳定性系数和岩层裂隙分维数给出四带划分方法。

Abstract: Based on the integration process of strata “collapse - breaking - bending - subsidence”, the strata failure and movement were analyzed. Considering the difference of the fracture development and the strata movement, the fracture zone is divided into quasi-continuous zone and block articulated zone. Thus, the four zone division of “caved zone, block articulated zone, quasi-continuous zone and continu- ous deformation zone” is set up, and the division criterion of the four zones is put forward by using hinge condition of strata structure, coefficient of rock mass stability and fractal dimension of strata fracture.
