得出在类似地质条件下的支护形式需要以锚杆索的及时主动性能为基础
) Abstract: The support question of headentry of 66111 coalface in Xinzhuangzi Colliery of Huainan Mining-Group is a typical roadway stability control question about large dip and composite roof
The article simulated different support methods with FLAC5
0,and reached a conclusion that the support method under similar condition needed a positive and initiative bolting support system,then take reinforcement measures to achieve high strength and integrity
The combined support method using anchor and U-shelf can effectively control the deformation of surrounding rock, with reference to similar condition roadway controlling
