| 摘 要： | 本文以相似材料物理模拟、有限元数值模拟和力学分析为手段;对条带法开采控制地表沉陷进行了深入的研究.揭示了条带法开采顶板岩层的破坏过程、破坏形态、破坏范围及整个覆岩体的移动与变形规律,特别是对波浪状下沉在覆岩中的传播机理和传播高度进行了较深入的探讨.给出了覆岩中波浪状下沉传播高度与条带采留宽度尺寸之间的关系和条带法开采地表下沉系数的表达式.划分出了条采覆岩破坏的三个影响带.在此基础上,提出了控制地表沉陷条带来留宽度设计所遵循的三个原则:即地表允许变形原则,煤柱稳定性原则和回采率原则.根据这三个原则,得出了条带采留宽度合理尺寸新的确定方法.所得结论对条带开采设计具有指导意义.

| Abstract: | Based on the simulation test with similar material and finite element numerical analysis, this paper studies the problem of the surface subsidence caused by strip mining in depth. The regular pattern of the movement and deformation of the overlying strata have been exposed. Three principles and the new calculating method to determine the proper size of pillar and mining width have been presented. The results of studies are of directive significance for the design of strip mining. |
