GMS在露天转地下水害防治中的应用

 为了评价再造阻水墙在露天转地下防治水工程的适应性,以安徽新桥矿业有限公司露天转地下防治水工程为例,考虑强降雨条件下露天坑积水、地表河流渗漏、北部侧向径流大量补给的情况,利用3DMINE建立地层模型,通过切分剖面导入GMS8.0软件Map模块建立复杂多图层概念模型,并基于Modflow模块建立多灾源条件下露天转地下工程地下水区域渗流数值模型,对再造阻水墙的适应性进行数值模拟.结果表明：利用GMS8.0软件可以精细、实时地模拟再现水文地质条件复杂的防治水工程的阻水动态过程.再造阻水墙在该矿山-180m标高以上部分墙内外水力梯度变化较大,阻水效果明显,适应性强.

Applications of GMS in the Prevention and Control of Water Disasters During the Transfer from Open Pit Mining to Underground Mining

In order to evaluate the adaptation of reconstructed water-resisting wall for the prevention and control of water disasters during the mining transferring period from open-air to underground, by taking water control project of Xinqiao Mining Corporation in Anhui Province as example, a numerical analysis was conducted. Considering the large supply of open pit water, surface water seepage, and northern lateral flow in the condition of strong rainfall, a stratigraphic model is established by using 3DMINE, and through syncopating profile into the Map module of software GMS8.0, a complex concept model with many layers is created and then based on the Modflow module of GMS8.0, a seepage numerical model of ground water region during open pit mining transferring to underground mining under the condition of many plagues source is established. Results show that GMS8.0 software is able to finely and real-time simulate and rebuilt a water-resisting dynamic process for the prevention and control of water under complex hydrogeological conditions. For the part of reconstructed water-resisting inside and outside wall that the elevation is above -180m, the hydraulic gradient change is large. And water block effect is obvious and has strong adaptability.
