Use in path delays for delays where the timing is dependent on when particular mining blocks are scheduled. They might include such things as walking the equipment from one location to another (deadheading), or any other planned delay, timed to coincide with the completion of a mining block (e.g. planned maintenance).

Adding an in path delay

To enter an in path delay in the input path, select Insert Blank Row from the right click menu and then open the Activity drop down list for the blank row. Select the required Non Productive Activity from the list. The words In Path Delay will be displayed in the Scheduling Task column.

Delay duration

The duration of the delay is specified in the "Entered % / Delay / SP Qty" column. The duration can be entered in either calendar, operating or roster hours, according to the delay time base that you specify.

End of period delay

An in path delay can also extend to the end of the current time period. This is called an "end of period delay" and the duration should be set by typing in EOP.

Delay time base

Calendar

If the delay type is set to Calendar, the duration must be entered in calendar hours.

Calendar delay types will ignore the roster and can therefore occur in both rostered and non-rostered time. If the non-productive activity selected for the in path delay is an operating delay, the delay will also report operating hours in the non-rostered time.

For calendar delay types, the "Actual % / Delay" in the Output Path will also be in calendar hours.

Roster

If the delay type is set to Roster, then the duration must be entered in calendar hours.

Roster delay types will obey the roster and they can therefore only occur in rostered time.

For roster delay types, the "Actual % / Delay" in the Output Path will also be in calendar hours.

Operating

If the delay type is set to Operating, the duration must be entered in operating hours.

Operating delay types will obey the roster and they can therefore only occur in rostered time.

For operating delay types, the "Actual % / Delay" in the Output Path will also be in operating hours.

A non-productive activity which is non-operating can be entered as an in path delay and still be set as an operating delay type. In this case the duration of the delay will be entered in operating hours, but there will be no operating time reported for that delay.

Summary of Delay Types

A summary of these delay types is presented in the following table.
