煤矸石充填重构土壤水分再分布与剖面气热变化试验研究

Shuitu Baochi Xuebao, 2017
为研究煤矿区用矸石作为垫底基质进行土壤剖面重构土壤水分再分布过程和剖面热扩散与气体浓度变化特征，以指导工程设计和重构土壤熟化技术应用，在实验室设计了一种煤矿区重构土壤水气热运移模拟装置，通过布设在土柱系统不同深度的温湿度传感器和CO2浓度检测仪，连续监测重构土壤剖面含水量、温度和CO2浓度。结果表明：煤矸石层具有良好的阻水性，阻碍水分的入渗，增加上层土壤的持水能力。但是，煤矸石的持水性差，煤矸石层的含水量远低于土壤层10%左右；煤矸石具有更佳的热扩散性，在加热过程中煤矸石层的温度远大于土壤层 ...
