摘要
矿岩可崩性是衡量矿岩发生崩落的难易程度,对于崩落法开采矿山,首采分层开采后,上覆矿岩能否连续冒落是矿山重点关注的问题之一。研究依托敦德铁矿,在岩体质量分级基础上,基于 Laubscher 崩落图法分析了矿岩可崩性,为矿山掌握首采分层开采后围岩可崩性提供了依据,对于矿山设计、生产具有重要的指导意义。
The caveability of the rock can measure the difficulties of the caving of ore rock. For the mine developed by caving method, after the first-mining slicing, whether the overlying ore rock can continuously inbreak is one of the key problems for the mine. The study is based on Dunde Iron Ore. On the basis of Laubscher caving diagram method, the paper analyzes the caveability of the ore rock. It provides references for the caveability of the first-mining slicing for the rear surrounding rock. It has great significance for mining design and production.
