分段凿岩阶段出矿嗣后充填法在黄岗铁矿的应用

主要介绍阶段充填采矿法在厚倾斜矿体中的应用,概述采切工程布置、回采设计和生产过程中需要注意的问题。分段凿岩阶段出矿嗣后充填采矿法在黄岗铁矿的应用,提高了生产效率,降低了综合成本,取得了较好的经济效益,同时确保了采矿作业安全,保护了地表生态环境。结果证明分段凿岩阶段出矿嗣后充填采矿法在回采厚矿体中具有极大的优越性。

Application of sublevel rock drilling and stage ore removal afterwardsback-filling mining method in Huanggang Iron Mine

This paper mainly introduces the stage filling mining method in the application of inclined thick ore body, an overview of the mining engineering arrangement, mining design and the problems should be noticed in the process of production. The application of sublevel rock drilling and stage ore removal afterwards back-filling mining method in Huanggang Iron Mine has improved the production efficiency, reduced the comprehensive cost, achieved good economic benefit, ensured the safety mining operations at the same time, and protected the surface ecological environment. The result shows that the sublevel rock drilling and stage ore removal afterwards back-filling mining method has great advantage in mining thick ore body.
