The sequence in which areas are to be mined is an interactive process that involves the user and the ICAMPS system. To assign mining areas to a machine, the user points to the areas in the order they will be mined. Color coded graphical feedback lets the user see which areas have been assigned to a machine. The user also maintains the technological sequence of mining among the machines by assigning precedences where necessary. The simulator then follows the user specified mining sequence and precedence requirements and reports the duration and cause of any delays.
