利用自行设计的岩石渗透试验系统,采用稳态渗透法测试了10件标准煤矸石试样非Darcy渗流时的渗透特性。通过最小二乘法对渗流速度和压力梯度进行回归分析,得到煤矸石的Darcy流渗透率、非Darcy流渗透率和非Darcy流β因子。研究结果可为工程中煤矸石做充填材料提供参考。
Using the self-designed rock infiltration test system, the infiltration characteristics of non-Darcy seepage of 10 standard coal gangue samples were tested by steady-state infiltration method. By regression analysis of seepage velocity and pressure gradient by the least squares method, Darcy flow permeability, non-Darcy flow permeability and non-Darcy flow β factor were obtained. The research results can provide a reference for the filling material of coal gangue in the project.
