| Abstract: | The stability of mined-out area is depended on pillar and roof in mine using room-and-pillar mining method.The failure patterns of pillar and stope roof are expounded.Based on the theory of underground pressure and strata control,the mechanics mechanism of pillar and stope roof is analyzed,and the factors influencing the stability of pillar are summarized. |
