Using the Calendar File in Short-Term Scheduling in GEOVIA Minex

Did you know that you can better utilize the Calendar File in GEOVIA MinexTM within short-term scheduling? Users can enter detailed information in the Minex calendar file on maintenance, downtime or planned stoppages for any equipment – either within the same calendar or in separate calendars.

Different calendars can have different shift timings or production factors. You can also add different calendar numbers for various excavators for short-term planning to include planned equipment maintenance. The following example shows part of a Minex .ascii calendar file for a particular excavator, factoring in maintenance time. You can edit this file according to your requirements.

You might have already used Month, Week and Days as scheduling time boundaries, but you can also click on the clock icon next to Month(s) to use a date control file (.ctl format) to control and execute time steps defined by you. You can also create your own time steps down to the hour. Please ensure that your reserve database is up-to-date and accurate enough to work in the short term.

1. To browse for the .ctl file, click the clock icon and select the .ctl file format (this can be created in an application such as Notepad on Windows)

2. Your .ctl file needs to be in the following format. Note that you will have to adjust the start time with the .ctl file manually, for instance changing the start time to STARTDATE 01-JAN-20 08:00.

01-JAN-20 07:00
01-JAN-20 19:00
02-JAN-20 07:00
02-JAN-20 19:00
