摘要
针对深井开采覆岩结构变形的特殊性,提出基于应力场转移的深井覆岩结构形变模型。采用三维半解析数值计算和现场综合试验与勘测的方法,给出采动岩体沉陷移动的分带、分区特征及突变集中变形和阶段性滞缓移动现象的动态演化规律,为深井开采覆岩与地表移动变形灾害控制提供科学理论依据。
In view of the specification of structural deformation in overlying strata of deep mining, we proposed a model for the structural deformation in overlying strata of deep mine based on the transfer of stress field. Through the theoretical analysis, 3-D semi-analytical numerical calculation and field tests and investigation, we gave out the zonal and strip characteristics of subsidence movements in rock mass induced by mining and the dynamic evolutionary rule of mutation collective deformation and the phenomenon of phased slow movement. All of these provide scientific and theoretical bases for disaster control of overlying strata and surface subsidence and deformation in deep mines.
