| 摘 要： | 伏萨尔梁属不连续介质结构模型，物理意义明确，计算简便，原来用于研究层状裂隙岩体中地下采场顶板脱层后的稳定性，因这种状况与露天采场内地下采空区顶板剥离卸载后的状况相似，故对伏萨尔梁法进行修正，将其应用露天采场采空区处理研究，并依据伏萨尔梁法基本原理开发了高台阶分区处理大面积采空区工艺，该工艺已应用于洛阳栾川钼业公司露天矿大面积采空区处理，收到了良好的效果。

| Abstract: | The conception of Voussoir Beam was mentioned at the first by Mr Evans in 1941.Due to its clear physical meaning and simple culculation mode,it was applied to analyse the stability of roof of underground stope located in bedded rock with cracks.Since the underground stope roof in open pit is of similar structure,the Voussoir Beam theory has been revised and applied to treatment of goafs in open pit.The practice of using Voussoir Beam theory to treat big goafs of Yichuan molybdenum ore open pit mine in Luoyang was successful. |
