Study on Influence of Blasting Operation on Design of Roadway Cross-section

摘要：

A roadway was usually excavated by blasting operation when drilling and blasting method was used for roadway excavation, so it is necessary to take the influence of blasting operation on the design of roadway cross-section into consideration. This paper studied the relation between blasting parameters and cross-sectional parameters of roadway under the condition of wedge and cone cut, and obtained the regularity of blasting parameters and cross-sectional parameters of roadway. Studying the relation between blasting parameters and cross-sectional parameters of roadway is not only favorable to the acquisition of reasonable cross-sectional parameters of roadway and blasting parameters, but also to the increase of roadway advance rate under the condition of guaranteeing safe driving.
