Quality assessment of the raw input - material properties data quality

CHALLENGE

Ore grade control and TI deparments do not have visibility of the quality of the material properties provided through the input raw data, so, in case of data deviations, no actions are driven by the site in order to correct and improve it, as it has a direct impact on the quality of the stockpile blockmodels.

SOLUTION

Dedicated page called "Properties Null and Outside Ranges" that exposes the quality of the material properties provided in the raw data, which is one of the main parameters that feed the stockpile blockmodels (along with the geospatial data). The aformentioned page, besides the Site Data QA Overview and the Stockpile Data QA Overview, enable the application to cover the most relevant parameters to be considered when evaluating the quality of the blockmodels.

To access the "Null and Outside range properties (Beta)" page, the user should follow the steps below:

  1. Click on "Stockpile data quality" icon.

  2. Click on "Null and Outside range properties (Beta)"

  3. Select the start and end date (8 days max)

  1. Click on "Choose stockpile" which will display a list of stockpiles that recorded material movements for the selected period of time.

  1. From the list select the stockpile of interest

  1. The page will displayed the following information related to the selected stockpile:

  • - Total events: N° of dump events recorded in the database.

  • - Total % events with anomalous value: % of events with have properties out of range and null properties values calculated from the total dump events recorded.

- Total % events with values outside range: % of events with properties out of range calculated from the total dump events recorded.

- Total events with null value: % of events which properties with empty values calculated from the total dump events recorded.

- Property: list of properties tracked in the stockpile blockmodel.

- Range: Uppe

r and lower limit configured in the application for the properties tracked in the stockpile blockmodel which are defined by each site.

- Total Number of events with anomalous properties: N° of events which have either a null or outside range value per each particular property.

- Total Number of events with properties outside range: N° of events which have values outside range.

- Total Number of events with null material properties: N° of events which have empty values per each particular property.

Note: as can be inferred , anomalous properties are those with either null or outside range values or both.

VALUE

  • Increase the understanding of the quality of the raw input data, therefore the quality of the stockpile block models.

  • Enable sites to correct on time eventual data deviations.

  • Support site ownership over the input data.
