Blasting — AI-optimized blast design & fragmentation
AI Autopilot tunes hole pattern, stemming, powder factor and delay timing against geology and downstream processing targets. Better fragmentation means less oversize, faster dig rates and lower kWh/t at the primary crusher.
概要
Blasting sets the entire mine-to-mill chain in motion. Oversize boulders become problems at the primary crusher; fines steal recovery at leaching. The blast is the only step where the entire downstream p80 distribution is practically determined.
Traditional blast design relies on templates and a senior blaster's intuition. That is a 10-year mental model being applied to ore that is increasingly heterogeneous as mines get deeper and lower grade.
BrainiAll AI Autopilot ingests borehole MWD data, geological models, prior blast performance, and measured post-blast fragmentation. It proposes hole spacing, burden, stemming height, powder factor and initiation sequence that produce the target fragmentation envelope for what the plant wants downstream.
Autopilotの機能
連続的・多変数制御 — 単一ループPIDではありません。アドバイザリ層アーキテクチャにより安全性はそのまま維持されます。
Geology-aware blast design
MWD data + block models guide hole pattern per rock domain — not one-size-fits-all.
Fragmentation control
Post-blast fragmentation imagery trains the model to hit downstream p80 with every shot.
Vibration & air-blast limits
Enforces PPV and dBL constraints near sensitive receptors — regulator-ready records.
Powder factor optimization
Minimum explosives for target fragmentation — less cost and less backbreak.
Initiation sequence
Inter-hole and inter-row delays tuned to direction of throw and bench geometry.

Fragmentation done right pays everywhere downstream: faster dig, smaller primary feed, lower grinding energy per ton, and better flotation recovery. A 10% reduction in oversize events at primary crushing can unlock 2-4% sitewide throughput uplift with zero capex.
