落矿
breaking ground
l旧伙旧ng落矿(breaking ground)使矿石与矿体分离，并破碎到适应块度的作业。落矿是矿石回采的主要作业之一，其作业费用占回采费用比较大的比例，如用分段或阶段强制崩落采矿法时，其落矿费用约占回采费用的1/3。落矿分为爆破落矿(又称崩矿)、自然崩落落矿、机械落矿和水力落矿等。现在和以后的相当长的时期内，金属矿山(或矿岩属中等硬度以上的其他矿山)主要用爆破落矿。矿石可崩性好时，利用自然崩落法落矿也占有相当的比重。机械和水力落矿仅适用于松软矿石，但已很少使用。对落矿的要求是:作业安全，矿石损失与贫化小，应尽可能使爆破范围以外的矿岩和工程受破坏程度缩小，矿石块度符合需要，需要二次破碎的大块矿石少，落矿强度符合需要，费用低。 (龙凌霄)
