Study on developing an automatic software to design tunnel blasting passport in autocad

Abstract

Automating the process of designing tunnel blasting passport to create smooth boundaries is an urgent issue in country’s actual conditions. This paper presents the method of developing automatic design software based on the optimization foundation theoretical methods, graphical methods as well as automatic drawing in AutoCAD methods. The software's interaction with AutoCAD is a new and important factor to help completing an automatic closed cycle on the computer from data entry to blasting passport export in AutoCAD, thereby contributing to increasing production efficiency and reducing risks in tunnel excavation.
