摘要
按照《工程岩体质量标准》以及采准巷道的实际稳定情况,以定性和定量的方法,分别对程潮铁矿已揭露的-302 m水平进行了矿岩工程质量分级评价,并对下部几个分段的矿岩工程质量做出了预测。针对不同等级的矿岩选择了相应的支护方案。分级分区结果与预测结果符合矿山实际情况,所选择的支护方案行之有效。
According to the criteria for classification of engineering rockmass and the actual stability state of mining preparation tunnels, the engineering quality of rockmass at -302 m sublevel of Chenchao Iron Mine is determined and evaluated by qualitative and quantitative methods. The engineering quality of rockmass at low sublevels is predicted furthermore. According to the different evaluation results, different reinforcing methods are selected. The evaluated and predicted results coincide well with practical cases, and the reinforcing methods are effective.
