摘要
目前岩矿标准试件测出的抗压强度严重偏高，而实际碎磨中碰到的都是形状极不规则的自然矿块，过去对不规则矿块抗压强度测定的方法不够完善且问题较多，基于此本文提出了确定不规则自然矿块抗压强度的新方法。
The paper points out that the compression strength measured from standard rock specimen is severely higher than that in practice. Main problem is that the ore blocks in practice are all irregular natural ore blocks. Therefore the paper has advanced a new researching method on resistance to crushing of irregular blocks and has provided useful method and practical engineering data for crushing engineering of rocks and ores.
