| Abstract: | Based on the supporting problem of deep well soft rock roadway,combined with form and characteristics of intake well pit bottom drift deformation and failure on the third level of Beier 6 mine in Pingmei Environmental Energy Development Co.,Ltd.,and analysis the reason and mechanism of the damage,according to its destruction form and law,it suggested that pressure support technology,take "resistance after assignation" graded and grading combined support technology,and then consolidate,dynamic maintenance,which can effectively control the deep soft rock tunnel deformation and the soft failure roadway under high for deep well offer beneficial reference for the experience. |
