Datamine Task Scheduler (DTS) is a Gantt chart scheduler specifically designed for underground and open pit scheduling that is suitable for operational short-term and long-term planning. DTS can schedule both production and non-production tasks such as maintenance, workplace preparation and shift changes. Mine planners can interactively update schedule rules and dependencies between tasks or use advanced levelling algorithms to automatically resolve scheduling conflicts. Gantt charts and many other reports provide operations with rich mine planning reports. Integration of DTS in Studio mine design software enables mine engineers to dynamically and interactively see the effects of changing designs and updated reserves on schedules.
