为了补充普朗铜矿地质特征研究以及探明矿区裂隙渗流特征，基于 COMSOL 软件对
普朗铜矿裂隙渗流进行数值模拟。通过人工测窗法、三维激光扫描法和数字式全景钻孔摄像法对
矿区的节理裂隙进行全面测量，调查开采前后矿区岩体裂隙张开度、倾向倾角、分布特征等情况。
利用 Monte-Carlo 法生成裂隙网络模型并导出矿区岩体裂隙的几何参数，用 COMSOL 软件对普朗
铜矿中裂隙进行渗流数值模拟。模拟结果得出，矿区的孔隙率为 2.56%，渗透系数为 6.52×10-8 m/s，
对普朗铜矿的开采和资源评估具有重要意义，为其他类似矿山中裂隙渗流的数值模拟提供借鉴。
In order to supplement the geological characteristics of Pulang Copper Mine and explore the
characteristics of fracture seepage in mining area，the numerical simulation of fracture seepage in Pulang
Copper Mine is carried out based on COMSOL software. By means of artificial window method，3D laser
scanning method and digital panoramic borehole camera method，the fractrue opening degree，fractrue dip
angle and crack distribution characteristics of mining rock mass are investigated. The fracture network model
was generated by Monte-Carlo method and the geometric parameters of fracture were derived. The fracture
model and seepage numerical simulation were carried out by COMSOL software. The simulation results show
that the porosity of the mine area is 2.56% and the permeability coefficient is 6.52×10-8 m/ s，which is of
great significance to the mining and resource evaluation of Pulang Copper Mine，and provides a reference for
the numerical simulation of seepage flow in other similar mines.
