The Web app blast holes drill design data can easily be synchronized into the Fielder app using the “Drill Log App” in the image below. The holes and rows details, hole depth, hole angle and azimuth can be easily synchronized into the Fielder app. Furthermore, the drill operator drilling information, blast bench observation features (hard, soft, water, clay, etc.) and actual drilling depth data can be modified in the mobile app and synchronized into the web app. In both ways the data can be synchronized for better visibility of actual blast data.

List View

After completing the drill shot design in the Strayos Fielder app, Users can switch between Map View and List View to manage and monitor the drill plan (1).

The List View provides a detailed overview of all drill rows and their corresponding drill hole information (3). Users can add new drill holes to any row by selecting the + Add Hole option (4). Additional rows can be created using the + Add Row option at the bottom of the drill plan (8), while unwanted rows can be removed using the Remove Row option (7).

Each drill hole displays its current drilling status (6), allowing Users to monitor progress throughout the operation. To begin drilling, Users can select the status icon for a drill hole and assign the appropriate drilling machine. Once all holes within a row have been completed, the Mark Drilled option (5) can be used to update the drilling status for the entire row.

Users can also synchronize project data with the Strayos Web Platform and access additional project options using the Sync and More Options menu located in the top-right corner of the screen (2).

Note: The numbers in parentheses correspond to the numbered callouts shown in the figure below.

Map View

The Map View provides a graphical representation of the drill shot design, allowing Users to view the complete drill layout, drill hole positions, and the current drilling status. Users can monitor drilling progress and perform drilling operations directly from the map.

To begin drilling, Users should double-tap the desired drill hole, select the appropriate drilling machine, and start the drilling process.

The Map/List toggle (1) allows Users to switch between Map View and List View. The Layers Menu (2), located on the right side of the screen, provides additional map display options and tools that can be enabled or disabled as required. These options include:

• Satellite Map (3): Displays satellite imagery as the map background.
• Driller Location (4): Displays the current location of the driller on the map.
• Drone Map (5): Displays the drone orthomosaic synchronized from the Strayos Web Platform.
• Labels (6): Displays the label or identification number for each drill hole.
• Design Length (7): Displays the planned depth of each drill hole.
• Drilled Length (8): Displays the actual drilled depth of each completed drill hole.
• Add Pin (9): Allows Users to place reference pins at specific locations on the map.
• Upload KML (10): Allows Users to import KML files into the Strayos Fielder app for additional map overlays and reference data.

The + and − controls on the left side of the screen allow Users to zoom in and zoom out of the map for improved visibility and navigation.

Note: See the figure below for the location of each Map View feature and tool.

Start Drilling

To start drilling, Users should open the required Project and select the drill hole they wish to drill. If a drilling machine has not yet been assigned, the Strayos Fielder app will prompt Users to either select an existing drill or add a new drill. Once a drill has been selected, Users can begin the drilling operation.

See the figure below for an illustration of selecting a drill hole and assigning a drilling machine.

Finish Drilling

After the drilling operation has been completed, tap the Finish Drilling button to stop the drilling process. The application automatically stops recording the drilling time and saves the drilling record for the selected hole.

If additional drilling information needs to be recorded, tap Add Hole Info to continue with the remaining hole details.

See the figure below.

Enter Hole Length

After selecting Add Hole Info, the application prompts Users to enter the actual drilled hole length.

Enter the measured hole length using the on-screen numeric keypad or adjust the value using the increment and decrement controls. Once the correct value has been entered, tap Next to continue.

See the figure below.

Enter Hole Angle

The application will then prompt Users to enter the actual Hole Angle.

Enter the measured hole angle using the numeric keypad or adjust the value using the increment and decrement controls. After entering the correct value, tap Next to proceed.

See the figure below.

Enter Hole Azimuth

Finally, enter the measured Hole Azimuth for the selected drill hole.

Use the on-screen numeric keypad or the increment and decrement controls to enter the correct azimuth value. After confirming the value, tap Next to save the information and complete the hole data entry process.

See the figure below.

Add Hole Information

After entering the hole details, Users can record additional information for the selected drill hole by tapping Add Feature, Add Photo, or Add Comment.

• Add Feature – Record geological features encountered during drilling, such as Overburden, Coal Seams, Voids, Clay, Rock Layers, or any other geological conditions relevant to the operation.
• Add Photo – Capture or upload photographs of the drill hole, geological features, or surrounding conditions for documentation.
• Add Comment – Add observations, notes, or any additional information related to the drill hole.

After all required information has been entered, Users should tap Done to save the recorded data and complete the hole information.

See the figure below for an illustration of the Add Hole Information screen.

Complete the Drill Shot

After a drill hole has been completed, its status is automatically updated in both the List View and Map View. The completed hole is displayed with its assigned status and color, allowing Users to easily monitor drilling progress across the entire shot.

Repeat the same drilling process for each remaining hole until all holes in the shot have been completed.

For faster operation, the List View also provides the following options:

• Mark Drilled – Marks all drill holes in the selected row as drilled.
• Reset Row – Resets the drilling status of all holes in the selected row, allowing the row to be drilled again if required.

See the figure below for an illustration of the completed drill holes in the List View and Map View.

The Bottom Navigation Toolbar provides quick access to the primary features of the Strayos Fielder app. Users can navigate between different modules without leaving the current project.

The toolbar includes the following options:

• Home – Returns Users to the project dashboard, where drill projects can be viewed and managed.
• Strata – Displays the list of available geological feature types and their corresponding color codes used for geological logging.
• Add Drills – Allows Users to add, edit, and manage drilling machines available for drilling operations.
