【摘要】 利用突水资料进行矿区地下水数值模拟,不仅节省了资金,而且可以达到更好的数值仿真效果。首先, 根据水文地质条件概化,建立了矿区地下水渗流的数学模型为非均质二维承压水越流系统模型。然后,运用突水资料对模型进行检验,模型求解运用三角网格有限差分法。模型检验中不仅各观测孔的实测水位与计算水位拟合较好,而且模拟流场与实测流场也基本吻合。最后,利用所建模型进行预测表明,-100 m水平以下煤层的开采,矿坑涌水量大,开采成本较高。更多还原

【Abstract】 It is not only to save bankroll, but also to achieve better effect of numerical emulation using the data of water invasion to put up groundwater numerical simulation. First, according to the simplifying of hydrogeological condition, the groundwater seepage mathematics model of the coal mine area is developed. The model is a heterogeneous two-dimensional confined flow with leakance. Then, the model is checked up with the data of water invasion and solved with the finite difference of triangle gridding. Through the model checked, the fitting of the measured water level and the computed water level of each observation well is good. Moreover the simulated flow field and the measured flow field are basically fitted. Finally, the model forecast to the exploitation of coal below -100m proves that the mine hydraulic discharge is tremendous and production costs are higher.更多还原
