摘　　要：文中采用UDEC离散元数值模拟方法,对相同留宽、不同采宽条件下条带开采地表移动变形规律进行了模拟研究,确定了“建下”压煤开采的最佳条带方案,并得出了地表移动变形随采宽变化的规律,为今后类似条件下条带开采设计和条带开采岩移预计参数的选取提供借鉴。In this paper,UDEC discrete element numerical simulation method was used to simulate the surface movement and deformation law of the strip mining under the conditions of the same reserved width and different mining width.Best strip plan for the compressed coal mining was determined under the buildings,and the laws of the surface movement and deformation changing with the mining width were obtained,which provided the reference for the design of the strip mining and the selection of the rock movement prediction parameters under the similar conditions in the future.
