| Abstract: | The formation and development of goaf overburden ＂three zones＇is closely linked to the overburden stress distribution of goal 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＂. |
