摘　　要：论文将抛石挤淤方法首次应用于露天矿工程,采用能量守恒原理和功能互相转化原理分析抛石挤淤方法在阴湾排土场积水坑中的挤淤深度,利用数值模拟分析抛石挤淤的过程和作用范围以及挤淤深度,理论计算和数值模拟互相补充。按照该研究成果施工后半年多内,期间伴随大降雨,该区域现场未发现不稳定迹象,表明该方法科学可行,成果可靠。The method of backfilling rocks to squeeze out ooze was applied in engineering practice of the open pit mine for the first time, achieving expected effect. Based on the principle of conservation of energy and work - energy mutual transformation, the ooze depth in the plash of Yinwan waste dump was analyzed. Numerical simulation method was applied to analyze the process and action range of backfilling rocks to squeeze out ooze, and the ooze depth, and the simulation result was combined with that of theoretical calculation. The result was applied in construction practice and was proved reliable, without any sign of instability during engineering practice of more than haft a year accompanied by heavy rain.
