The application is used to record the availability of the various active headings in the mine. This information is automatically added to an ODBC database so that reports can be generated for the relevant personnel.

The database stores records containing information about the availability of each heading. Whenever a change is made to the status of a heading a new record is added to the database and the date and time that the change was made is stored. Similarly, sets of records containing the headings’ resource data and other information are also stored. When the database is viewed using the HARP software the most recent records are combined and are displayed as a table. The historical data, i.e. the earlier records, can also be displayed.

Each heading can be linked to external files (e.g. plans and photographs) which can be quickly accessed using menu items, hotkeys etc.

A predefined set of reports can be generated using HARP. These are produced in HTML format. Custom designed reports can also be produced using third party software e.g. MS Access.

As well as table views of the data, the headings can also be displayed in plan and 3D views. The views are synchronised which means that whichever heading is selected in one view becomes selected in the other views.
