Blasting pretreatment of underground bedrock and solitary rock in shield section under complex environment
This paper introduces an advanced pretreatment method of bedrock and solitary rock in shield section under complex environment.Combined with the geological survey data and field environment,the deep-hole controlled blasting method is used to deal with the bedrock and solitary rock in shield section,reasonable blasting parameters and microsecond network delay are selected,and multiple safety protection measures are taken,such as multi-channel coverage protection,drilling large aperture vibration reduction holes,etc.Finaly,good blasting effect is obtained,construction period is shortened,and the cost of shield excavation is effectively reduced,which provides a reference for similar projects.
