摘　　要：通过相似材料模拟实验方法,研究地下开采引起岩层内部的移动和变形规律,揭示了煤矿开采上覆岩层中断裂、破坏、移动与变形及离层的产生、发展与分布的时空规律,为指导实施离层充填减沉技术及工程实践提供了科学依据。根据岩石变形和移动的分布特征,将采动覆岩进行分区,建立理论模型,为进一步进行计算机数值模拟奠定了基础。By means of the test study of similar material simulation, the law of rock mass deformation and movement are reappeared in coal mining. Rock rupture, breakage, movement and the space-time rules of the separated layer generation, development and distribution in overburden are given . It presented some technical foundations for using the technique of the surface subsidence controlled by grouting in overlying-separation layer. According to the characters of rock deformation, damaged overburden was divided into some zones, which establishes the basis for building the model and developing computer numerical simulation.
