Abstract: In order to determine the supporting mode of a minelike layered roof,firstly,by understanding the engineering geology of the surrounding rock of a mine roof and the basic characteristics of the surrounding rock,the mechanism of the layered roof of the mine is analyzed,and a layered roof is obtained.The general destruction mode.Then the ore stability of the mine is combined with the engineering practice,and reasonable structural parameters of the stope are proposed.The controlled blasting technology is used to maximize the integrity of the layered roof.Finally,through the analysis and comparison of several different support methods,combined with the characteristics of the layered roof in the project,it is determined that the support of the layered roof is long anchor cable support.The support method can change the safety structure of the layered roof support and improve the integrity and carrying capacity of the roof support structure of the type.At present,this kind of support method has been gradually promoted and applied in the mine.At the same time,in view of the current status of roof management,the problems of mine roof management are summarized,and a reasonable and effective roof management system is formulated to improve the safety of mining operations.
Key words: Stope, Layered roof, Bolting, Long bolt support, Combined support, Roof management
