| 摘 要： | 运用粒子反向示踪理论,根据安徽铜陵新桥硫铁矿各含水层的水文地质条件、工程地质条件,利用抽压水试验得出的渗流系数、给水度等岩性特征,针对突水水源识别问题,建立Modpath的矿井突水可视化模型,并以时步分段量化研究水源渗透规律,分析了矿井突水的水源来向、侵害范围、影响程度等特征元素。研究结果验证了突水点上层含水层的岩溶裂隙带和断裂带对突水点的重要补给关系,并且有较强的直观判别能力;模型可以清晰判别分析矿井突水现象。

| Abstract: | By using reverse tracer particle theory, the seepage coefficients and the specific yields of Tongling Xinqiao pyrite aquifers are obtained according to their hydro-geological and engineering geological conditions by pump pressure test. To identify the source of water inrush, a Modpath visualization model for water inrush is established. Water penetration rules are quantitatively researched by time step, and source direction, influencing range and degree of water inrush are analyzed. Results show that the fissure zone and the rift zone of the aquifer upon water inrush are important supply for the water inrush. The model has strong visual discrimination ability and can clearly discriminate mine water inrush. |
