In order to improve the grouting efficiency and accuracy of phosphogypsum based self-produced gas expansion slurry, the change in density of phosphogypsum based self-produced gas expansion slurry with time was analyzed. Based on fluid mechanics theory and the time-varying model of slurry density, a mathematical model of the seepage diffusion pressure of the slurry during the self-produced gas expansion stage was established. Through a self-built phosphogypsum based self-produced gas expansion slurry similar model experiment system, the seepage pressure variation of phosphogypsum based self-produced gas expansion slurry in the fracture network during the self expansion stage was studied, and the mathematical model of the seepage diffusion pressure of the slurry was modified to verify the rationality of the modified mathematical model of seepage diffusion pressure. The results show that the trend of slurry density over time follows a negative exponential power characteristic. During the self expansion process, the diffusion area of the slurry increases and the increase in diffusion area of the slurry becomes smaller and smaller. The relative error between the theoretical and experimental results of the seepage pressure at the monitoring point does not exceed 10%, proving the rationality of the modified mathematical model for seepage diffusion pressure.

为提高磷石膏基自产气膨胀浆体的注浆效率和准确性,分析磷石膏基自产气膨胀浆体密度随时间的变化,基于流体力学理论和浆体密度时变模型,建立浆体在自产气膨胀阶段的渗流扩散压力数学模型。通过自行搭建的磷石膏基自产气膨胀浆体相似模型试验系统,研究裂隙网络中磷石膏基自产气膨胀浆体在自膨胀阶段的渗流压力变化,修正浆体渗流扩散压力数学模型,验证修正后的渗流扩散压力数学模型的合理性。研究结果表明:浆体密度随时间变化趋势符合负指数幂特征;在自膨胀过程中,浆体扩散面积越来越大,浆体扩散面积的增幅越来越小;监测点的渗流压力的理论结果与试验结果的相对误差不超过10%,证明修正后的渗流扩散压力数学模型具有合理性。

为提高磷石膏基自产气膨胀浆体的注浆效率和准确性,分析磷石膏基自产气膨胀浆体密度随时间的变化,基于流体力学理论和浆体密度时变模型,建立浆体在自产气膨胀阶段的渗流扩散压力数学模型。通过自行搭建的磷石膏基自产气膨胀浆体相似模型试验系统,研究裂隙网络中磷石膏基自产气膨胀浆体在自膨胀阶段的渗流压力变化,修正浆体渗流扩散压力数学模型,验证修正后的渗流扩散压力数学模型的合理性。研究结果表明:浆体密度随时间变化趋势符合负指数幂特征;在自膨胀过程中,浆体扩散面积越来越大,浆体扩散面积的增幅越来越小;监测点的渗流压力的理论结果与试验结果的相对误差不超过10%,证明修正后的渗流扩散压力数学模型具有合理性。

In order to improve the grouting efficiency and accuracy of phosphogypsum based self-produced gas expansion slurry, the change in density of phosphogypsum based self-produced gas expansion slurry with time was analyzed. Based on fluid mechanics theory and the time-varying model of slurry density, a mathematical model of the seepage diffusion pressure of the slurry during the self-produced gas expansion stage was established. Through a self-built phosphogypsum based self-produced gas expansion slurry similar model experiment system, the seepage pressure variation of phosphogypsum based self-produced gas expansion slurry in the fracture network during the self expansion stage was studied, and the mathematical model of the seepage diffusion pressure of the slurry was modified to verify the rationality of the modified mathematical model of seepage diffusion pressure. The results show that the trend of slurry density over time follows a negative exponential power characteristic. During the self expansion process, the diffusion area of the slurry increases and the increase in diffusion area of the slurry becomes smaller and smaller. The relative error between the theoretical and experimental results of the seepage pressure at the monitoring point does not exceed 10%, proving the rationality of the modified mathematical model for seepage diffusion pressure.
