Abstract
Traditional blasting design is mainly based on experience, blasting passport in AutoCAD is drawn manually, this causes time-consuming, costly, waste of manpower. For this reason, the development of a reliable software for gate road blasting design is an ideal way to solve the current problems. However, in Vietnam the work is still far from enough, because until date there are no software can resolve both process of calculation blasting parameters and automatically drawing blasting passport in AutoCAD. Therefore, in order for developing a suitable model to solve the problems in the current gate road construction, it is necessary to create an algorithm linking between blasting parameters calculation process and drawing blasting passport in AutoCAD process. This paper introduces an automatic algorithm linking between blasting parameters calculated by Delphi programming language and AutoCAD to help drawing automatically. Through the characterization of input data for gate road, calculation of geometric parameter and algorithm of blast-hole pattern for each section was introduced in details. The algorithm was applied to automatic blasting passport design for gate road in underground mining with semi-circle arch which verified the feasibility of the algorithm.
