In open pit mines and quarries, mining of ore beneath overlying burden is mostly performed by the help of appropriate blasting processes in easing of the excavation of adjacent rock. Reaching to required blast outcomes is expected to affect the succeeding processes, directly. Therefore an easy control and the specific blast programme is necessary, most of the time. In this study, first, many effective factors on blast design were investigated; secondly, the related theoretical and or practical equations up to date which include these factors were studied. A user-driven computer model was developed using Pascal software language to be able to fulfill design considerations of the blast area interacting with the inputdata keyed in. To design with, the developed computer model was put into test running it under several predetermined values of different blast design considerations. Later, it was run several times using mechanical characteristics of rocks sampled from a private limestone quarry and recommendations were suggested on blast design.
