摘　　要：在分析目前深部开采条件下岩层移动角确定存在问题的基础上,在一定的地质采矿条件下,探讨了岩层移动角随开采深度、开采厚度及煤层倾角等的变化规律,建立了深部开采条件下移动角的计算公式。指出在同一矿区,不同的开采深度、开采厚度条件下,移动角并不是一定值,而是与采深、深厚比等存在复杂的非线性关系。最后,实例验证了岩层移动角确定的合理性,从而为最优设计保护煤柱提供理论依据。Based on analyzing problem of displacement angle of stratum mining in deep-lying conditions at present, under a determination geology mining conditions, the changing principle of displacement angle of stratum is probed into, along with exploiting depth, thickness and coal inclination angle etc, and its calculation formula is established in deeplying. In a mine, under different mining depth and thickness conditions, the displacement angle of stratum is not const, but complicated un-liner relations changing with mining depth and the ratio of mining depth and thickness. At last, the reasonable of determination on displacement angle of stratum is verified with example, and theory basis is provided for designing coal pillar.
