摘　　要：为了研究厚层风积沙出露地表的煤矿沉陷规律,以葫芦素煤矿为例,利用RTK技术,联合其他观测仪器,进行现场地表移动观测,获得了地表移动相关参数,为有效解决地表建(构)筑物压煤问题、指导矿井安全生产、丰富该区域的覆岩移动变形规律,提供了可靠依据。In order to research the regular of coal mining subsidence where the Thick Aeolian Sand on the surface,taking Hulusu Coal Mine as an example.Using RTK technology and combining with other observation instruments,surface movement observation on the spot,obtained the related parameters of surface movement.The research provide reliable basis including effectively solve the problem of surface construction(structure) pressing coal,guide safe production in mines.It also enriches the law of overburden movement and deformation in this area,raise the overall benefit of the mine.
