| Abstract: | This paper mainly analyzes the supporting capacity of the chamber in a shaft on the basis of its service time and the lithology of the wall rocks,and then works out the shoring parameter according to the theory on combined arch.In practice,the combined shoring with anchored net,anchored steel belt,sprayed concrete and anchorage cable has been applied in shaft-chambers and great benefits have also be achieved in technology and economy. |
