| Abstract: | Due to the particular difficulties of support design and construction technology of deformation and damage in extra softrock,classification by analyzing the deformation of this laneway,the whole supporting system and construction technique of deformation and damage in extra softrock are put forward,based on the hydrology geology and-300m wall rock conditions of the laneway in shaft station of the Hemushan diggings of Maanshan Iron & Steel Co.Ltd.The real deformation measured results show that this supporting system and construction technique can effectively control the wall rock deformation of deformation and damage roadway in extra softrock.It proves that this system has good supporting effect and technical value,worthing popularizing. |
