基于GMS的矿井涌水量预测

Prediction of Mine Water Inflow Based on GMS

矿井涌水是矿山安全开采中难以解决又必须面对的问题。GMS(groundwater modeling system)具有强大的前、后处理功能,实现了地质模型、水文地质参数等的可视化,提供的自检功能为调试模型提供了极大方便。以宁夏某矿为例,应用GMS对其水文地质条件进行概化,建立水文地质结构模型和水文地质概化模型,通过MODFLOW模块对其涌水量进行预测。结果表明:三维地质模型具有很好地可视性,研究区地层能够更加直观的得以展示,模拟所得水位与实测水位拟合效果在置信区间内,模拟区首采面的涌水量的预测值为1450 m~3/h。为矿山开采、工程建设中涌水量预测的研究提供了更为直观、更为便捷的方法。

It is difficult and necessary to solve the problem of mine water inrush in safety mining.The powerful pre-processing and post-processing functions of Groundwater modeling system(GMS) achieves visualization of geological models and hydrogeological parameters.The self test ability provided by GMS provides great convenience for debugging models.Taking a mine in Ningxia as an example,the hydrogeological conditions is generalized and the hydrogeological structure models and hydrogeological generalization models is established based on GMS.Then the water yield is predicted through the MODLOW module of GMS.The results indicate that the three-dimensional geological model has good visibility,and the strata in the study area can be more intuitively displayed.The fitting effect between the simulated water level and the measured water level is within the confidence interval.The predicted water inflow of the first mining face in the simulated area is 1450 m~3/h..This provides a more intuitive and convenient method for the prediction of water inflow in mining and engineering construction.
