摘要
吉林镍业公司大岭矿矿岩结构复杂，为典型的低品位难采矿床。采矿方法选定后，落矿方式的研究对能否顺利回采非常重要，文中重点对回采落矿进行了叙述，对今后生产及类似矿山具有一定的指导意义。
The ore structure of Daling Mine is complex in Jilin Nickel Industry Corporation, it is typical low grade difficulty mining deposit. After determined the mining method, the study of stopping ore fall's way is very important to whether stopping successfully. This paper emphasized the stopping ore fall, its guidance to future production and similar mines.
