为探索煤炭地下开采是否对地表土壤湿度产生影响,以典型的荒漠化矿区神东矿区为研究对象,在构建土壤湿度监测指数和尺度化土壤湿度监测指数的基础上,通过消除遥感数据时相差异的影响,基于矿区两期遥感影像数据,反演得到研究区土壤湿度分布图,从矿井尺度上分析地下煤炭开采对神东矿区9个矿井的地表土壤湿度的影响,并利用实地调查土壤湿度数据对其进行验证。结果表明:地下煤炭开采活动对大柳塔、活鸡兔、锦界、榆家梁、石圪台、补连塔等矿井浅层土壤湿度产生了负面影响,导致采区土壤湿度小于非采区,与实地调查结果相吻合;上湾-尔林兔、乌兰木伦、哈拉沟矿井浅层土壤湿度并未受到地下采煤活动的显著影响。实践表明,开展植被建设、加强矿井水的循环利用等手段可以部分消除采矿活动的负面影响。

In order to explore the impacts of coal mining on land surface soil moisture,the Shendong Mining area,a typical desert mining area,was selected as the research region,baesd on the establishing the soil moisture monitoring index and scaled soil moisture monitoring index.elimination of the infuence of phase difference for remote sensing data,soil moiture distribution image was obtained by inversion with two issue of mining area remote sensing image data. In mine scale,the effect of underground coal mining on soil moisture was analyzed for main nine mines inShendong Mining Area.The field measured soil moisture was used to validate the impacts of coal mining.The results indicated that undergroundcoal mining produced negative impacts on land surface soil moisture in Daliuta,Huojtu Jinjie,Yujaliang.Shigetai and Bulianta mines and soil moisture in mined area was lower than soil moisture in un-mined area,which consistended with the results of field measurement.Meanwhile,Shangwan-erintu, Wulanmulun and Halagou mines were not obviously affected by underground coal mining.The pratice showed vegetation constructionand mine water circulation utilization could partally eliminate the negative influence of underground coal mining.
