摘　　要：根据地层的沉积特征和相似材料模拟,将固体密实充填开采岩层移动特征分成有结构关键层和无结构关键层2类模式进行描述。并针对有结构关键层情况,建立了固体密实充填岩层移动模型,模型由3部分有机组成,即结构关键层力学模型,结构关键层上方岩体移动模型和基岩面上方土体移动模型。最后将建立的岩层移动模型用于工程实例取得了良好的效果。According to the sedimentary characteristics of stratum and similar material simulation, the strata movement characteristics for the solid compacted backfilling are divided into two types for describing. One is structure key layer; the other is no structure key layer. Aiming at the second type, the solid compacted backfilling strata movement model is established, that is made up of three organ- ic composition parts, namely structure key layer mechanical model, rock movement model above the structure key layer and the soil movement model above bedrock surface. At last, taking the model based on the structure key stratum as an engineering project, it has achieved good effect.
