应用室内模拟试验与野外试验相结合的方法， 对半干旱地区煤矸石山浅层矸石风化物与黄土的水分特性进行了比较研究． 结果表明： 矸石风化物因具有颗粒粗、孔隙大、渗透系数高、田间持水量、凋萎系数和累积蒸发量低的特点， 故有一定的保水性能； 尤其旱季， 矸石山剖面０～３０ ｃｍ 的有效水含量， 裸露矸石明显高于覆土矸石和黄土， 且其剖面水分含量在０ ～６０ ｃｍ 内与深度呈显著正相关． 并提出和论证了能充分利用水分的矸石山“薄层覆盖复垦”新技术．
The water characteristics of shallow gangue weathering material and loess in coal gangue hill in semiarid area were compared with the method of indoor simulation and field experiment. The results showed that the gangue weathering material had some water retention properties due to its coarse grain size, large pores, high permeability coefficient, low water holding capacity, wilting coefficient and cumulative evaporation. Especially in the dry season, The effective water content of bare rock was significantly higher than that of covered soil and loess, and the water content in the profile was significantly and positively correlated with depth within 0 ~ 60 cm. And put forward and demonstrated that can make full use of moisture Gangue Hill “thin layer reclamation” new technology.
