| 摘 要： | 根据矿岩工程地质条件、岩石力学性质及采矿方案建立二维相似模型试验。通过试验研究不同采矿区域周边的近域与远域尤其是顶板覆岩的受力、变形和塑性破坏特性,分析该种方法开采的竖直方向影响高度,确定覆岩移动变形规律及铝土矿开采的影响程度。试验表明,放顶与切顶方法可有效控制采场压力、控制上部岩层的均匀沉降。

| Abstract: | Based on the geological conditions, rock mechanics properties and mining schemes, a two-dimensional similarity model test was established. the near and far areas around the mining areas were studied through experiments., especially the stress, deformation and plastic failure characteristics of The influence height of the mining method was analyzed. The rule of overburden movement and deformation and the influence extent of bauxite mining were determined. The test indicated that roof caving and roof cutting can effectively control stope pressure and uniform settlement of upper strata. |
