摘要
本文通过研究银山铅锌矿北山区采矿方法并结合有限元计算，提出了在现有采矿方法的基础上，对采场底部结构及上盘加设锚杆支护新工艺。实践表明，这项新工艺具有显著的经济效益和社会效益。
Study on the mining technology in Beishan Area of Yinshan Lead-Zinc Mine and relevant finit element calculations have led to the intreduction of a new bolt support technology which has been applied on the stope bottom structure and the upper side wall. It is shown in practice that this new support techndogy has yield ed remarkable economic and social benefits.
