摘要
在大量落矿采矿法的采场,普遍采用设有二次破碎水平的底部结构,不但采准工作量大,而且不能解决高效落矿与低效出矿的矛盾.为此,凤凰山铜矿大胆革新,设计采用无二次破碎水平、振动连续出矿的平底底部结构,较好地解决了上述问题,取得了满意的效果.
In the stope for the mass caving method, the bottom structure, at which the secondary crushing level was arranged, was used generally. This layout not only was heavy in developmental work but also could not solve the contradiction of high-efficiency caving with low-efficiency ore removal. As viewed from this, a bold innovation has been conducted in Fenghuangshan copper mine. A bottom structure with flat sill, without se-condary crushing level, for vibrated continuous ore removal has been designed to use for solving the previous problems, with a better and satisfactory result.
