摘　　要：以某露天煤矿为研究背景,根据该矿区工程地质特点,采用极限平衡法,针对易燃区边坡第1开采阶段进行边坡稳定性评价。通过计算可知,在保证内排跟进速度的情况下,第1阶段条采方案可满足矿区生产要求。在此基础上,结合现场实际情况,针对第2阶段边坡控制开采方案进行研究,进而确定条采煤层厚度、宽度、开采边界以及内排土场参数,确保露天煤矿安全生产。Taking a surface coal mine as the research background, according to the characteristics of engineering geology, using the limit equilibrium method, the paper carried out slope stability evaluation for the first mining phase of flammable slope. By calculation, under the condition of ensuring the inner dumping following up the speed, the first phase mining scheme can meet the requirements of mining production. On this basis, combining with the actual situation, the paper studied slope control scheme of the second phase to determine the seam thickness, width, mining boundary, inner dumping site parameters and ensure open-pit coal mine safety production.
