摘要
为探明阳城煤矿3305工作面矿井水的位置和赋存形态,选用井下三维高密度数据采集系统采集数据;反演模型选用浅层垂直细分三维模型,反演方法选用圆滑约束最小二乘法,借用三维可视化系统进行成图,得到工作面顶板地层电阻率三维数据体;而后运用切片技术对数据体进行切割,确定了矿井水的位置与赋存状态,保证工作面回采安全进行。
In order to ascertain the location and occurrence of the mine water in the 3305 working face of Yangcheng coal mine,the underground three-dimensional high-density data acquisition system is selected to collect data;the shallow vertical subdivision three-dimensional model is used for the inversion model,and the smooth constrained least square method is used for the inversion method,borrowing a 3D visualization system for mapping to obtain a 3D data volume of resistivity of the top slab of the working face;then use the slice technology to cut the data volume to determine the location and occurrence of the mine water and ensure the safety of the working face.
