Worked example
A drill-and-blast contractor delivers a production blasting programme at an open-cut metalliferous mine in regional New South Wales, drilling and charging benches under the operator's blast management plan and the Resources Regulator framework. The programme runs across a quarter, with each blast planned and fired under the statutory arrangements. The crew reviews the SWMS against the operation: the drilling-rig fume and respirable crystalline silica from rock dust are assessed, the blast exclusion zones are determined for fly-rock and air-blast, and the post-blast re-entry atmosphere controls are set. The dominant hazards are drilling fume and silica dust, blast fly-rock and vibration, premature initiation, and the post-blast atmosphere of fume and dust, so the SWMS specifies dust suppression and respiratory controls at the rigs, exclusion zones sized for fly-rock with positive clearance of all persons before firing, initiation under the statutory shotfiring controls, and re-entry only after the blast atmosphere has cleared and been checked. Charging follows the explosives controls with detonators kept separate until charging, and the blast is fired under the blast management plan with the exclusion confirmed. Misfire procedures are set so that a hole that does not detonate is managed under controlled re-entry rather than approached directly, and the firing sequence and tie-in are checked before the crew withdraws to the firing position. The drilling, blasting, and re-entry records are documented to the mining framework, and the programme runs without an uncontrolled fly-rock, premature initiation, or re-entry incident, with the records retained under the regulator's requirements.

Frequently asked questions
How are blast exclusion zones determined?
Exclusion zones are sized for the credible fly-rock range and the air-blast and vibration limits of the specific blast design, and all persons and unprotected equipment are positively cleared from the zone before firing. The SWMS specifies that the exclusion is determined per blast and confirmed clear before initiation, under the operator's blast management plan. Firing before the exclusion is confirmed clear is a prohibited step, because fly-rock can travel well beyond the immediate bench.
What controls the post-blast re-entry atmosphere?
A blast generates fume — including oxides of nitrogen and carbon monoxide — and dust, so the SWMS specifies that re-entry occurs only after the blast atmosphere has cleared, by ventilation or natural dispersal, and been checked. Re-entering too soon exposes the crew to toxic fume and dust. The re-entry control is treated as a distinct hazard from the blast itself, with the atmosphere confirmed before anyone returns to the bench or heading.
Why is drill-and-blast high-risk work?
It involves explosives and generates respirable crystalline silica, blast fly-rock, vibration, and toxic post-blast fume, managed under the mining safety framework with statutory shotfiring accountability. The fatal potential of premature initiation and fly-rock places it among the most tightly controlled mining activities. The SWMS treats it as high-risk and frames the controls around the explosives, exclusion, and atmosphere hazards within the operator's blast management plan.
How is the silica dust from drilling controlled?
Production drilling of silica-bearing rock generates respirable crystalline silica, so the SWMS specifies dust suppression at the rigs — water injection or dust collection — and respiratory protection where the dust cannot be fully controlled, with exposure monitoring. Silica is a recognised carcinogen and the drilling is a significant source. The dust controls at the rig are treated alongside the blast controls, because the drilling phase carries its own respiratory hazard separate from the blast.
How does this relate to a separate explosives-handling SWMS?
This SWMS covers the drill-and-blast operation including charging and firing, while the explosives-handling SWMS covers the transport, magazine storage, and on-bench handling of the explosives in more detail. The two are complementary — charging and initiation here reference the explosives controls, and the explosives-handling SWMS governs the storage and movement of product. Operators use both, with this SWMS focused on the drilling, charging, and blast execution.
