An integrated workflow for development headings and open-pit benches—from parameter modelling and hole patterns to optimization, engineering calculations, and design reports. Every design stage is governed by geometry, rock conditions, and engineering constraints, keeping parameter sources, calculations, and deliverables aligned. Development headings and open-pit benches use dedicated geometry, pattern, and verification workflows while sharing one editing and deliverable standard.

a lightweight web tool for tunnel blasting engineers. Quickly input blast hole data, calculate vibrations and delays, and visualize results in real-time — no Excel needed. Ideal for fast field drafts and early-stage design validation.
