摘要
某磷矿为缓倾斜中厚矿体,矿体中间赋存软弱夹层,针对其开采现状,开展此类矿体采矿方法探索研究,在大量查阅国内外相关文献的基础上,提出了2种可行的采矿方法,通过对比分析,认为采用机械化条带后退式采矿技术能够满足矿山大规模安全开采要求,理论上保证了低成本开采此类矿体的可行性,同时对国内外其他类似矿体起到借鉴意义。
In the paper,agently inclined and medium thick phosphate orebody which contains a soft intercalated layer is introduced.Therefore,the mining method for this kind of orebody is studied.On the basis of a large number of references at home and abroad,two feasible mining methods are compared,and mechanized strip backward mining method is better which can meet the requirements of mass production capacity and safety mining.Theoretically,the mentioned mining method can ensure low cost input and supply techno-economic references for other similar orebody.
