由露天开采剥离物和煤矸石组成的土体，水分渗漏严重，在低温季节无法形成冻土。在距离煤矸石土体表层一定深度构建阻水层，以提高煤矸石土体的水源涵养能力。然而，由于缺乏相关重构阻水技术（构造）数据集，目前在青海木里矿区实施土壤重构技术存在较大的不确定性。本研究利用室内土柱入渗试验、模拟降雨试验得到构建阻水层后的煤矸石土体入渗率数据集，结合数学统计方法以及数学模型拟合与评估，得到在构建不同阻水层下的煤矸石土体的入渗数据集，并通过实地验证评价发现，煤矸石粉碎物级配=2:5:3(1~2mm、0.5~1mm、< 0.5mm)，煤矸石粉碎物容重控制为 1.60~1.75g/cm2，W-OH浓度为3.5~4.5%喷洒量为2.5~3.5L/m2，PAM播撒量为在压实后的煤矸石表面干撒0.05~0.07g/cm2范围内阻水效果最佳。

Build a water blocking layer at a certain depth away from the surface layer of the coal gangue soil to improve the water conservation capacity of the coal gangue soil. However, due to the lack of relevant reconstruction water blocking technology (structure) data sets, there is great uncertainty in the current implementation of soil reconstruction technology in Muli Kuangqu, Qinghai. In this study, indoor soil column infiltration test and simulated rainfall test were used to obtain a data set on the infiltration rate of coal gangue soil after the construction of water-blocking layers. Combined with mathematical statistical methods and mathematical model fitting and evaluation, the infiltration data set of coal gangue soil under the construction of different water-blocking layers was obtained.
