Abstarct: Drilling and blasting is the most common method for excaveting rock in open pit mines. The goal of drilling and blasting is crushing the ore to the acceeptable dimention and transport them to out of mine. Also, blasting costs and damages after it (back break, land vibration, air blast, fly rock and … ) shuld be in their minimum values. Blast holes pattern, the amount of charge required (Main and bottom charge), blast start system and sequences are main factors to gain these goals. Management of these factors make the way easy to an ideal drilling and blasring operation. In order to manage well in any field, complete and accurate information is needed to provide a broad view of the subject to decide. Acording to increasing development of technology and due to mines are equipped with computer systems, using of blast management softwares is the best way to desirable results. These softwares have plenty of capabilities. Calculating drilling geometry such as burden, spacing, subdrilling and steaming height is one of these compabilities. In the next step required amount of explosives and Auxiliary equipment that are needed. In the next step required amount of explosives and Auxiliary equipment that are needed. Blast holes circuitry is one of the most important factors in blasting operations that are largely ignored today. If there is a databaxse that contains all the information of previouse blasting operation, then use of this information can help managers and engineers to decide better. If there is a comprehensive software with these campabilities, then the operation speed and accuracy of the results will be optimized. Software presented in this research that programming with Microsoft Visual Basic.NET 2010 and named Blastograph has these compabilities. It can design blast pattern, calculate specific charge, circuitry in different way, record blasting blocks, report in variuos shape and etc.
