高阶段大直径深孔嗣后充填采矿法在某铁矿的应用研究

Application Research on High-Sublevel Large-Diameter Longhole Cut and Fill Mining Method in an Iron Mine

针对某急倾斜厚大铁矿体的开采现状,开展采矿方法研究。在查阅国内外类似矿体开采现状的基础上,提出了几种可行的采矿方法。综合分析各采矿方法的安全、高效、经济等主要指标,认为采用高阶段大直径深孔嗣后充填采矿技术能够满足矿山大规模开采要求,可以实现急倾斜厚大矿体的低成本高效开采。同时对国内外其他类似矿体开采起到借鉴意义。

Aiming at the mining situation of a steeply inclined thick orebody, the research on the mining method has been conducted. On the basis of referring to the mining situation of similar orebodies at home and abroad, this paper proposes several feasible mining methods. Through the comprehensive analysis of the safety, efficiency, and economy indicators, it is considered that the high-sublevel largediameter longhole cut and fill mining technology can meet the requirements of the large-scale mining, and achieve the low-cost and efficient mining of the steeply inclined thick orebody. At the same time, it can also provide reference for the mining of similar orebodies at home and abroad.
