爆破落矿
ore break by blasting
度、单位炸药消耗量、炮孔或药室的布置、装药结构以及爆破技能等。 对于坚硬矿石，落矿费用中凿岩占60%一70%，爆炸材料占20%一30%，装药和爆破占10%一2()味。 (龙凌霄)匕ooPO}LJokLJong爆破落矿(ore break by blasting)通过爆破崩落矿石的作业。根据装药空间不同，落矿爆破分为炬吁L爆破和响室爆破。炮孔爆破按孔的深度分为浅眼爆破、中深孔爆破、深孔爆破。根据药包形状，落矿爆破分为柱状药包爆破和球状药包爆破。根据爆下矿石的碎胀状况，落矿爆破分为自由空间爆破和挤压爆破;自由空间爆破是指供爆下矿石破碎膨胀所需空间(补偿空间)足够大，能满足矿石的自由碎胀。 评价爆破落矿效果的主要指标是:凿岩劳动生产率(即凿岩工或设备每班钻孔长度及相应的崩矿量);矿石损失率;犷石贫化率;大块矿石产出率;单位炸药消耗量等。爆破落矿效果主要取决于矿石的坚固性、节理和裂隙的密度、矿体厚度、自由面数、炸药性能和密
