普朗铜矿大规模开采关键技术应用研究
|
摘要
普朗铜矿矿石品位低、矿体厚大、矿岩易崩落、地表容许塌陷,是自然崩落法采矿的理想目标。为了保证自然崩落法的成功应用,普朗铜矿组织开展了一系列井下大规模开采关键技术研究,主要包括矿床开采技术条件、矿体可崩性与崩落矿石块度预测、高中段大面积放矿控制技术、底部结构巷道稳定性和支护技术研究等,为应用自然崩落法开采打下了基础。
Pulang copper mine,with the characteristics of low ore grade,large and thick ore bodies,ore caving and allowable surface subsidence,is suitable for using natural caving method.In order to ensure the successful application of natural caving method,the key technologies of large-scale mining were studied in Pulang copper mine,including mining conditions of deposit,cavability of orebody,fragmentation prediction of caving rocks,ore-drawing control technology for high level and large area,stability of bottom structure and support technology.The study had provided reference for the application of natural caving method.
