| Abstract: | The purpose of gob-side entry driving is to arrange the roadway into the stress decreasing zone,which is beneficial to the maintenance of roadway.Appling FLAC to simulate the stress state of the roadway after tunneling,and filling the coal pillar,the results show that the stress has a big decrease and by using the results,a support scheme is proposed,which can be demonstrated via practice. |
