摘　　要：在研究开采沉陷引起的覆岩运动及其地表移动的规律时,采用相似材料模拟的方法,可以直观的表达出在工作面推进过程中,所引起的覆岩及其地表的水平位移、下沉量及其移动规律。通过实验表明,随着工作面的推进,煤层上覆岩层运动逐渐剧烈,水平位移和下沉量逐渐增大,直至达到充分采动后,水平位移和下沉量衰减并逐渐趋于稳定。In the research of mining subsidence movement rule, caused by the movement of overlying strata and surface, u- sing the method of similar materials simulation, it can be expressed in the working face advancing proeess, horizontal dis- placement, overlying strata and surface subsidence caused by its movement rule directly. Experiments show that, with the working face advancing, the overlying strata movement strengthens gradually, and horizontal displacement and subsidence increases gradually. Until it reaches the full subsidence, horizontal displacement and subsidence will attenuate and stabi- lize gradually.
