| 中文摘要: |
| 采空区覆岩“三带”形成、发展与其应力位移分布密切相关。本文以新集二矿1煤210108工作面采空区巨厚砂岩顶板为研究对象，采用数值模拟方法分析采空区覆岩应力位移场分布，结果可为采空区覆岩破坏及“三带”分布分析提供依据。 |
| 英文摘要: |
| The formation and development of goaf overburden “three zones”is closely linked to the overburden stress distribution of goaf. In this paper,we take the thick sandstone roof of face gob in Xin JI second mine 210108 as the subject ,the numerical simulation was used to analyse the distribution of gob overburden stress displacement field,which can provide the basis for the gob overburden damage and the distributed of “three zones” . |
