High intensive coal mining will impact on the moisture and eco-environment in the Blown-sand Region of the Northern Shaanxi Province. On the fissure of cut of No. 20108 coal face in the Yushuwan coal,by means of combi- nation between in-situ field monitoring and numerical simulation,a coupling model between moisture and heat on the influence of the fissure due to coal mining on the moisture transportation of the vadose zone was established. After vali- dation and calibration with field monitoring data from July 17th to 20th and July 25th to 30th,2014 respectively,rela- tive moisture and heat parameters could be acquired. Then this model can answer the influence degree and reveal the influence mechanism of fissures on moisture transportation. All these can provide reference for coal mining under water-containing and ecological restoration in the Blown-sand Region of the Northern Shaanxi Province and other similar regions.
