摘要:焦坪矿区大采深、厚煤层综放开采条件下,地表下沉量较小,呈现非充分的采动影响现象。通过相似材料
模型试验,分析了本区地质开采条件下工作面宽度、隔离煤柱尺寸、上覆岩层岩性与地表移动的内在关系,揭示
了岩层移动的基本特征。研究证实了深部开采条件下工作面间留设一定宽度的隔离煤柱对地表沉降起到有效的控
制作用,这可为本区及类似条件的其他矿井提供参考。

Abstract:A phenomenon of sub-critical mining subsidence appears in Jiaoping mining area in Shaanxi Province,
which is under the conditions of great mining depth,thick seam and fully-mechanized top-coal caving. By similar
material tests,the relationships of ground movement with the width of working face,the size of face-separated
pillar,and the lithologic characteristic of overlying strata are studied. The main characters of rock masses
movement are revealed. The achieved results prove that the face-separated pillars with a d
