Abstract: In view of the complexity and urgency of the controlling of underground engineering rock deformation,and based on the theory and experiments,the non-coupling compound charge directional rupture blasting technology is proposed,and its blasting mechanism are analyzed simply.Finally,the technology is applied to the actual construction of roadway.The measurement results of on-site rock deformation and internal force of bolt show that the charging structure can effectively control the deformation of surrounding rock,and reduce the disturbance to the surrounding rock.
