The Schedule File

A Schedule file is generated as part of operational scheduling, and is used to populate many screens derived from the Schedule ribbon (for example Update Schedule).

This topic describes the fields contained within the schedule file.

Mandatory Fields

Field Name	Type	Description
BLOCKID	Numeric.	A unique identifier for the block containing the material source for the activity.
PERCENT	Numeric.	The percentage of the activity being carried out on the block.
TIMENO	Numeric.	The period number in which the activity occurs.
LDRSEQ	Numeric.	The order per machine that the activity occurs in within one period.
ACTIVITY	Alphanumeric.	The type of activity being performed, for example drilling.
LOADER	Alphanumeric.	The name or description of a machine (for example "CAT573").
TYPE	Alphanumeric.	The type of machine (driller, loader, and so on).

Activity-Specific Fields

Field Name	Type	Description
CATEGORY	Alphanumeric.	The category of the material being mined during the loading activity. This is only shown for ‘Selective’ type activities. Loading is an example of this.
SLOT	Alphanumeric.	Destination of the material per category mined by the loading activity.
EXPR	Alphanumeric.	Used to define delay events and synchronisations between activities within a period. There is a custom code depending on the type of synchronisation. If it is a delay, there is a seconds value. Delay code example: `d=3780`. Synchronisation code example: `sf=Loader:LDR1:1`.
VALID	Numeric.	Computed field for internal validation of the schedule.

Truck And Haulage Fields

Field Name	Type	Description
H_TRUCK	Alphanumeric.	Haul truck selected to be used for the loading activity.
BNCHFCTR	Numeric.	Adjustment factor for the time taken to go between the block and the bench exit.
RAMPSCTR	Alphanumeric.	Name of the sector corresponding to the haulage between bench exit and pit exit.
SURFSCTR	Alphanumeric.	Name of the sector corresponding to the haulage between pit exit and destination.
DUMPSCTR	Alphanumeric.	Name of the sector corresponding to the haulage between destination and final dump point (only used for stockpiles and dumps).
TRUCKHRS	Numeric.	Total hours required by the trucks in order to complete the haulage.
CYCLTIME	Numeric.	Time per trip.
HAULDIST	Numeric.	Distance for the outward trip.
EFHLOAD	Numeric.	Distance for the outward trip calculated against a 0% gradient.
EFHEMPTY	Numeric.	Distance for the return trip calculated against a 0% gradient.

Reserves Fields Reported In The Schedule

Field Name	Type	Description
TONNES	Alphanumeric.	Amount of tonnes being mined by the activity. This is derived from the reserves based on the PERCENT mined by the loading activity.
DENSITY	Numeric.	Density of the material loaded (derived from the reserves).
VOLUME	Alphanumeric.	Volume of the material loaded (computed field) based on the PERCENT. Other production fields (as specified on the activity, for example DrillMTR).
PFLOW	Alphanumeric.	The PFLOW value on the block.
GRADE fields	Alphanumeric.	Displayed for records for the loading activity.
Product Recovery (any name)	Numeric.	A field that specifies the recovery of a block-category for a specific process destination. As with plant throughput, this is set within the options for ‘Normal’ type destinations. The value is a percent (0–100).
Plant Throughput (any name)	Numeric.	A field that specifies the throughput of a block-category for a specific process destination. Set within destinations for ‘Normal’ (Plant) type destinations. There is a throughput and recovery tab. The throughput can be specified for each block-category in terms of tonnes per time period.
Fields for pit, phase (pushback) and bench (any name)	Alphanumeric.	Generated by automated bench creation, this will be PIT, PHASE and BENCH however, you can use any fields for this alphanumeric information. If PIT, PHASE or BENCH are present in the file they will be automatically treated as this type of information.

Legacy Fields

These fields are no longer used, but are still included.

DRAW.
DRILL.
CRUSHER.
SHAPEID.

Field Selection Logic

The following pseudo-code demonstrates the logical process undertaken by the scheduler in order to pinpoint the correct data field and value during processing:

IF the ACTIVITY is selective (“Loading” is always selective) THEN.

IF ACTIVITY is “Loading” and BLOCKID is negative (this means it is a stockpile reclaim and the BLOCKID will identify the stockpile) THEN.

IF the machine processing type is tonnes THEN.

TONNES (numeric) – This is the tonnage being reclaimed.

Else.

VOLUME (numeric) – This is the volume being reclaimed.

ELSE.

There can be multiple rows for this activity, one for each category.

CATEGORY (alpha) – This is the category name.

PERCENT (numeric) – This is the percent of the block category being processed.

ELSE.

PERCENT (numeric) – This is the percent of the block being processed.

IF ACTIVITY is “Loading” THEN.

SLOT (alpha) – This is the destination for the material.

H_TRUCK (alpha) – This is the haul truck name.
