开采扰动下三圣铁矿渗流特性及涌水风险分析

Seepage characteristics and water inrush risk analysis of Sansheng Iron Mine under mining disturbance

河流下方矿体进行开采时,渗流稳定性是保证地下矿山安全开采的重要因素。为分析头道羊岔河对三圣铁矿井下开采渗流稳定性的影响,基于水文地质概念模型,采用Flac软件开展了三圣铁矿井下开采扰动影响下的渗流特性分析。结果表明:采场的回采受河流水位渗流的影响较小,矿坑无涌水风险。计算结果可为矿山安全开采提供参考。

Seepage stability is an important factor to ensure the safety of underground mining when mining ore bodies under rivers.To analyze the influence of the Toudaoyangcha river on the seepage stability of underground mining in Sansheng Iron Mine, based on the hydrogeological concept model, the seepage characteristics under the influence of underground mining disturbance in Sansheng Iron Mine were analyzed by using Flacnumerical analysis software.The results show that the stoping is less affected by the seepage of the river level, and there is no water inrush risk in the mine.The calculation results can provide a reference for safe mining in mines.
