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.
