为制定有效的矿井突水预警与防治对策,以单侯矿三采区为工程背景,基于现场地质钻孔编录数据,应用Surpac软件,构建三采区主要含水层三维可视化模型。利用该软件的三维交互式图形功能,直观显示了三采区主要含水层与5煤和1煤的空间位置、规模形态以及分布范围;通过统计分析与计算,分别给出了5煤和1煤回采工作面与邻近含水层的隔水厚度等值线图、邻近含水层与各个回采面的最小隔水层范围,圈定了流场面积与体积,提出了合理的回采顺序,能在复杂水文地质条件下进行分析和突水进行预测预防。

In order set up the effective mine water inrush early warning and the water inrush prevention and control countermeasures, based on No.3 mining block of Danhou Mine as the engineering background and based on the prepared data of the site geological boreholes, the Surpac software was applied to establish a 3D vis ualized model of the mine main aquifer.With the 3D interactive graph functions, the software could be applied to directly display the space location, scale morphology a nd the distribution scope of No.5 seam and No.1 seam as well as the main aquifer in No.3 mining block.With the statistical analysis and calculation, the water isolation t hickness contour drawing between the coal mining faces in No.5 seam and No.1 seam and the nearby aquifers could be obtained including the min water isolation layer scope between the nearby aquifer and each coal mining face.The flow field area and volume was determined.A rational mining sequence was provided.The analysis cou Id be conducted under the complicated hydrogeological conditions and the water inrush could predicted and prevented.
