摘要:
在龙首矿西二采区上部中段采矿方法由胶结充填法转为无底柱分段崩落法时,矿山面临着覆盖层形成及矿石损失贫化控制等一系列技术难题。首先提出了大体积胶结充填体诱导冒落覆盖层形成方案,分析得出胶结充填体具有较好的可冒性;然后对胶结充填体破碎后的块度分布规律进行了研究,结果表明胶结充填体在破碎过程中不会产生大量粉状物,因此不会造成矿石提前贫化;最后针对崩落法采场仅有的4个回采分段提出一种组合式放矿方案,并对该方案在矿石贫损控制方面的有效性进行了试验验证。将各项研究成果应用于现场生产实践,成功诱导顶板胶结充填体冒落形成覆盖层,在获得良好矿石贫损指标的基础上,使采场产能提升30%,采矿成本降低28%,在复杂开采条件下实现了低品位矿石的安全高效、低贫损及低成本开采。
