This paper describes a new digital Centralized Blasting System (CBS), which is currently being introduced into underground applications. The CBS makes use of the field-proven detonator and equipment technology of an electronic detonator system and existing mine radio communication networks. Therefore no capital investment for additional mine infrastructure networks is required for the deployment of the digital CBS. Components of the new system are a Remote Blasting Box for use at the actual blast site and a Master control unit 'Lockbox' which is located at the central blasting location of the mine. The system is operated via a PC based centralized blasting software. Several sophisticated safety devices guarantee the highest safety standards are maintained with the application of the new digital CBS.
