摘要:

为有效解决刚波夫门塞萨(Msesa)矿坑面临的复杂物性淤泥体处治问题,结合Msesa露天矿区水文地质条件、淤泥体物理力学特性等,利用数值模拟方法计算并结合工程实际,提出一套适用于废弃矿坑重新开发的淤泥体原位疏干排水及采掘技术体系。研究结果表明:将4孔疏干井均匀布设在采坑淤泥体最深部,总静态排水时间约45天,淤泥体储水排水时间约29天,实现淤泥体的超前疏排。提出的疏干采矿式清淤方案在技术、经济与安全方面具有明显优势,为露天矿采坑清淤与资源利用提供可推广的技术参考。

Abstract:

In order to effectively address the complex physical and mechanical challenges of sludge treatment in the Msesa open-pit mine, the hydrogeological conditions and physico-mechanical properties of the sludge body were investigated. Based on numerical simulations combined with engineering practice, a technical system for in-situ sludge dewatering, drainage, and mining suitable for the redevelopment of abandoned pits was proposed. The results show that when four dewatering wells are evenly arranged at the deepest part of the sludge body, the total static drainage time is approximately 45 days, and the sludge storage drainage time is about 29 days, achieving advanced pre-drainage of the sludge body. The proposed dewatering and mining-based dredging scheme demonstrates significant advantages in terms of technical feasibility, economic efficiency, and operational safety, providing a practical and transferable reference for open-pit mine dredging and resource utilization.
