摘　　要：矿产资源的不断开发导致矿坑涌、突水现象愈加频繁,此类问题多发生于大水矿山,为更好指导大水矿山深部开采工作,准确预测矿山深部开采矿坑涌水量至关重要。结合某矿区勘察资料、水文地质条件和观测井实测水位数据,利用Visual MODFLOW软件建立矿区水文地质数值模型,进行稳态与非稳态校正以及相关参数敏感性分析;根据该矿区-150 m水平矿坑真实涌水量拟合分析Drain模块水力传导系数值,运用识别后模型对矿山深部开采矿坑涌水量预测,结果表明-200、-250、-300、-350 m等不同水平矿坑正常涌水量为17209.82、18896.20、21299.31、23494.10 m^(3)/d,预测结果可为矿山防治水工作提供依据,以及为工程安全开挖提供保障。The continuous development of mineral resources has led to the increasing frequency of pit gushing and water inrush,which mostly occur in large water mine,so it is very important to accurately predict the water inflow in deep mining pits in order to better guide the deep mining work of large water mine.Combined with the exploration data,hydrogeological conditions and measured water level data of observation wells,Visual MODFLOW software was used to establish a hydrogeological numerical model of the mining area,and the steady-state and unsteady state correction and sensitivity analysis of related parameters were carried out.According to the fitting of the real water inflow of the pit at the-150 m level in the mining area,the hydraulic conductivity coefficient value of the Drain module was analyzed.The results showed that the normal water inflow of-200,-250,-300,-350 m and other pits at different levels was 17209.82,18896.20,21299.31 and 23494.10 m^(3)/d,which can provide a basis for mine water prevention and control and guarantee for safe excavation of the project.
