摘　　要：边坡高差大、整体稳固性差的边坡称之为为高危边坡。既要维护高危边坡的稳定,又要在高危边坡上采矿,是一对矛盾,矛盾的焦点是安全。在某露天矿山的高危边坡上进行了台阶采矿的试验研究。介绍了采矿方案的选择、回采爆破和充填的技术与工艺。现场试验获得了良好的技术经济效果,可供类似矿山参考和借鉴。Open- pit slope whose highness is great and overall stability is poor is called as high and dangerous one. Not only to keep high and dangerous Slope stable but also to mine ore in the slope are a pair of contradictions, and the focus of contradiction is safety. An experimental test of bench mining in the high and dangerous slope of a certain open- pit mine was made. The selection of mining plan, stope blasting and filling technology were described. A good tech - economic result was obtained from site test, and provided a reference for similar mines.
