摘要:

针对背斜区煤层由近水平变成倾斜,从背斜构造对排土场综合作用的角度对排土场参数做出优化,并对优化后安太堡露天矿内排土场边坡的稳定性做出分析和预测。综合考虑内排土场地质条件、采矿条件、气候条件、岩土物理力学性质、运输及排弃方式以及排土场地形地貌等因素,得出了内排土场技术参数和排土参数以及优化参数后边坡稳定的结论。

Abstract:

 According to coal seam from nearly level to tilt in anticline zone, the article optimizes dump parameters from the effect of anticline structure on dump, analyzes and predicts the slope stability of internal dump after optimization. Considering the geological conditions, mining conditions, climate condition, soil physical and mechanical properties, transportation and abandoned way and topography of dump, the author obtains the technical parameters and dumping parameters and the conclusion of slope stability after optimizing parameters.
