中文摘要：
应用土柱试验研究矿区充填复垦地煤矸石层水分竖直上移运动,分别设定三种不同的容重、泥岩和块度（直径小于1cm）的煤矸石质量百分比维度,研究水分上移高度和剖面含水量变化,研究结果表明：煤矸石中泥岩的风化程度越高,充填复垦地土壤的水分条件将越优越.在给定地下潜水位条件下,若不考虑地表蒸发的影响,煤矸石层水分竖直上移的高度可用二次曲面响应模型来描述.
英文摘要：
A soil pillar test was applied to study the vertical movement features of the moisture in the coal rejects layer of the backfill reclamation land in the mining area. The percentage dimension of three coal reject qualities with different volume- weight, mudstone and particle （diameter lower than 1 cm） was individually set up and was applied to study the moisture upward moving height and the water content variation of the cross section. The study results showed that the higher weathering degree of the mudstone in the coal rejects was and the more favorable moisture condition of the soil in the backfill reclamation land would be. Under the condition of the preset underground water table, if the influence of the ground evaporation was not considered, the response function model of quadratic curved surface could be applied to describe the vertical upward moving height of the moisture in the coal rejects layer.
