In this study, RBD(Rock Blasting Design) program was developed to perform easily on plans of rock blasting. This program has abilities as follows, that is, the test blasting plan, the bench blasting plan, and the blasting vibration analysis. The value of geological property and blasting constants was offered by database, input value of variety constants repeatedly is planned out, faster and easier. And a value of input constant may be used by user for necessity.
