Your First Blast — Step-by-Step Walkthrough

This guide walks you through creating a blast design from scratch — from opening Kirra to exporting a production-ready file.

---

Before You Start

• A modern browser (Chrome recommended)
• Hole survey data (CSV, DXF, or other supported format) or bench coordinates to generate a pattern manually

---

Step 1 — Open Kirra

1. Open Kirra in your browser by navigating to the application URL.
2. The Welcome popup appears with version info, a quick guide, and licence details.
3. Dismiss the popup to start.

The Welcome popup on startup.

Step 2 — Import Your Data

1. Go to File → Import.
2. Choose your format: CSV, DXF, DTM/STR, OBJ, PLY, GLTF/GLB, IREDES, KML, SHP, or LAS.
3. Select your file and complete any import mapping if prompted.
4. The canvas auto-centres on your imported data.

Kirra confirms when data has been loaded successfully.

If prompted, click Continue to proceed.

Tip: See the Importing section for format-specific guidance.

Step 3 — Toggle Between 2D and 3D

• Use the view toggle to switch between 2D (plan view) and 3D (elevation view).
• 2D is ideal for pattern layout; 3D shows terrain and hole depths.

---

Step 4 — Select Holes

• Click a hole to select it.
• Shift+click to add or remove holes from the selection (multi-select).
• Selected holes highlight on the canvas.

---

Step 5 — View Hole Properties

• Right-click a hole to open the context menu.
• Choose Properties (or equivalent) to view and edit collar, toe, diameter, bearing, inclination, subdrill, timing, and charge info.

---

Step 6 — Generate a Pattern (Optional)

If you are building a pattern from scratch:

1. Go to Pattern → Add Pattern.
2. Choose Rectangular, Polygon, or Line-based.
3. Enter burden, spacing, and hole count (or draw a boundary).
4. Click Generate — holes appear on the canvas.

See Pattern Generation for full details.

---

Step 7 — Assign Timing

1. Open the Connect toolbar (floating toolbar on the right).
2. Use the Connect tool to set delay sequences between holes.
3. Assign inter-hole and inter-row delays as required.

See Timing Sequences for advanced options.

---

Step 8 — Add Charging (Optional)

1. Open the Charging panel.
2. Select one or more holes.
3. Build deck configurations: stemming, boosters, explosive products.
4. Apply to selected holes.

See Charging Overview for the full workflow.

---

Step 9 — Run Analysis (Optional)

1. Open the Surface toolbar.
2. Click Blast Analysis Shader for vibration modelling.
3. View predicted PPV, Voronoi rock distribution, and blast statistics.

---

Step 10 — Export

1. Go to File → Export.
2. Choose your format: CSV, DXF, GLB, GeoTIFF, IREDES, etc.
3. Configure any format-specific options.
4. Save the file to your chosen location.

Step 11 — Print

• File → Print to PDF — Print the current view directly to PDF.
• File → Print from Template — Use an XLSX template for formatted reports.
