摘要:

地下矿采空区的恢复和治理对矿区及周边环境有重要影响。以某金属矿地下采空区为研究对象,基于MIDAS GTS NX软件进行数值模拟,对该区域分步开采及充填过程、采空区废石充填后上覆岩层的稳定性进行分析,同时对该区域实施废石充填+胶结充填接顶后采空区安全稳定及地表河流的影响情况进行研究。研究结果表明,对采空区实施废石充填+胶结充填接顶可有效减缓围岩应力,保障地表河床的稳定性,显著提升采空区结构稳定性,使整体处于安全水平。

Abstract:

The restoration and management of underground mine goafs significantly impact mining areas and their surrounding environments. Using an underground goaf in a metal mine as the study object, this research employs the MIDAS CTS NX software for numerical simulations. The analysis focuses on the stability of the stepwise mining and filling process, as well as the overlying strata after waste rock filling. Additionally, the study examines the safety and stability of the goaf and the impact on surface rivers after applying waste rock filling + cemented filling to the roof. The results show that the waste rock filling + cemented filling to the roof effectively alleviates surrounding rock stress, ensures the stability of the riverbed, and significantly enhances the structural stability of the goaf, maintaining overall safety levels.
