全段高组合凿岩爆破技术在会宝岭铁矿的应用

Application of Combined Drilling and Blasting Technology with Entire Sublevel Height in Huibaoling Iron Mine

介绍会宝岭铁矿中深孔分段空场和高阶段大直径深孔联合回采工艺技术,与采用单一中深孔分段空场法形成对比,对较厚矿体采用全段高组合凿岩爆破技术,实现安全、高效开采,提高资源回收率,技术经济效果明显。

The combination mining technology of sublevel open stope and high-level large-diameter long hole mining in Huibaoling Iron Mine is described, and compared to the single medium length hole sublevel open stope method, for the thick ore body the safe and efficient mining is achieved, the recovery rate of resources is increased, and the technical and economic index is largely improved by combined drilling and blasting technology with entire sublevel height.
