矿石损失与贫化矿石损失与贫化ore loss and dilution kuongsh一sunshl yuP一nhuo矿石损失与贫化(ore 1055 and dilu‘ion)指工业储量的丢失与矿石品位的降低矿石损失分为非开采损失和开采损失两大类。非开采损失是指与开采无关的矿石损失，如矿山设计中规定不采的各种永久性保安矿柱，以及由于地质和水文地质条件而不能开采的工业储量。开采损失是指:开采范围内生产期间产生的矿石损失，损失的矿石包括无法开采或开采经济上不合理的边角矿体;由于生产技术和工艺方法不 完善而未采下的矿石;由于各种原因残留在采场未被 放出的采下矿石和运输中撒落的矿石。矿石贫化分为 不可避免贫化和可避免贫化两类。不可避免贫化是指 设计允许的贫化，一般包括:开采极薄矿脉时按最小采 幅要求开采一部分围岩;矿体中无法剔除的夹石:采用 崩落采矿法时，在覆盖岩下放矿时随矿石放出而混人 一部分废石;采用充填采矿法时一部分高品位矿粉撒 落在充填材料中而丢失等。可避免贫化是指设计不允 许采下的围岩和夹石;生产管理不善引起富矿损失和 岩石混人等。 回采过程中产生的矿石损失贫化又分为一次矿石损失贫化和二次矿石损失贫化。一次矿石损失贫化是 指落矿过程中产生的矿石损失贫化，其原因是:由一于矿体边界变化、凿岩爆破技术和生产管理不完善等一部分矿石未崩下;部分围岩和夹石随矿石崩落混人采 下矿石中二次矿石损失贫化是指出矿过程中产生的矿石损失贫化.其原因是:采用崩落采矿法和留矿采矿法时·在放矿过程中.由于下盘倾角不足，一部分矿石残留于下盘;采用崩落采矿法时，在覆岩下放矿造成岩石混人;采用留矿采矿法时，放矿过程中围岩片落混人矿石中。采用崩落采矿法时，矿石损失贫化产生的过程 见图。
