摘要
介绍了某铁矿的地质概况。针对其矿岩结构为破碎厚大矿体的现状,通过比较上向水平分层充填法、阶段空场嗣后充填法、分段空场嗣后充填法的优缺点,决定采用分段空场嗣后充填法为主、阶段空场嗣后充填法和分段空场嗣后充填法为辅的采矿方法。采矿试验获得的经济技术指标都高于标准要求,具备实际可行性。
The geological situation of an iron mine is introduced.The rock structure of the mine is broken and thick ore body.By comparing the advantages and disadvantages of the upward horizontal layer filling method,the stage open field subsequent filling method and the stage open field subsequent filling method,it is decided to adopt the mining method with the stage open field subsequent filling method as the main method,the stage open field subsequent filling method and the stage open field subsequent filling method as the auxiliary method.The economic and technical indexes obtained from the mining test are all higher than the standard requirements and have practical feasibility.
