摘　　要：为分析膏体充填开采孤岛煤柱覆岩移动破坏规律,确定充填开采控制地表沉陷的充填率阈值,基于充填膏体作用机理,并结合现场地质条件,采用相似材料模拟和理论分析,研究了采用充填法和垮落法开采孤岛煤柱分别引起来的覆岩移动规律,根据地表变形规律分析了充填开采控制地表沉陷的充填率阈值,并通过现场实测进行了地表下沉分析。In order to study strata movement and failure laws of isolated coal pillar with paste filling mining, and determine the threshold value of filling rate by using filling mining to control surface subsidence, based on the paste filling mechanism and the geological conditions, adopting similar material simulation method and theoretical analysis, the laws of strata movement caused by filling method and caving method separately are researched, and the filling rate threshold value of using filling mining to control surface subsidence is analyzed according to surface detormation law, and surface subsidence analysis is carried out by means of site test.
