摘　　要：通过现场实际调查研究,详细分析了露天矿内排土场滑坡的影响因素,并研究了滑坡的特征及演化过程。根据上述分析,确定了主要因素,提出了预留煤柱滑坡防治方法;在确定排土场力学参数的基础上,建立分析模型,对不同安保煤柱参数下的排土场稳定性进行了分析。Based on engineering exploration, some factors that landslide of internal waste dump were analyzed, landslide characteristics and evolution process were studied. According to the above analysis, main factors were determined, the control method of coal pillar for landslide was proposed; and rock parameters of dump were selected, the model for stability analysis of dump in the different of coal pillar parameters was established.
