摘要
针对无底柱分段崩落法在实际应用中由于矿块结构参数变化,以及矿体中夹杂有大量的伟晶岩,而导致在回采过程中出现的损失贫化或永久损失的难题,通过改进掘进巷道和出矿方式,最大限度的降低了矿石的损失贫化从而提高矿石的回采率。
Pillarless Sublevel Caving is widely adopted in underground iron parameters of ore blocks or due to occurrence of a lot of pegmatite inclusion, there is To solve this problem, the mode of tunneling and ore withdrawal is improved, depletion is maximally reduced while ore recovery is remarkably increased. ore mine. Due to change of structural often ore loss or depletion during stoping. which brings the effects that ore loss or depletion is maximally reduced while ore recovery is remarkably increased.
