摘　　要：为了获得大采高工作面回采过程中的沉陷规律,在大采高回采工作面地表上方建立地表移动变形观测站,结合地质、采矿因素进行综合分析研究,得到工作面走向和倾向的下沉及水平移动规律,并预测整个工作面回采全过程中的沉陷规律,为工作面的实际回采提供了依据。In order to obtain the subsidence patterns during the mining process of the high mining height working face,a surface movement and deformation observation station is established above the surface of the high mining height working face.Combined with geological and mining factors,comprehensive analysis and research are conducted to obtain the subsidence and horizontal movement patterns of the working face’s strike and inclination,and to predict the subsidence patterns throughout the entire mining process of the working face,providing a basis for actual mining of the working face.

关 键 词：大采高工作面 地表下沉 地表水平移动 曲率变形
