沙厂铁矿露天转地下采矿方法的确定

Determination of Open-pit Transferring to Underground Mining Method for Shachang Iron Ore

根据沙厂铁矿多层复杂矿体的条件,在露天转地下开采过程中,分别采用空场法和崩落法,实现露天转地下开采的平稳过渡,保证了矿体开采的安全、经济、高效。

According to the conditions that Shachang Iron Ore has multilayer comprehensive orebody, during lhe process of open-pit lransferring to underground mining, open-stope method and caving method are adopted respectively, achieving smooth transition from open-pit to underground mining. It guarantees the safe, economic and efficient orebody mining.
