What Are Mining Lighting Solutions?
Answer: Mining lighting splits into two scopes. Underground workings need ATEX/IECEx-certified explosion-proof fixtures — Iway ROBUS EX01-C, EX02-A and EX02-B (Ex db IIC T6 Gb / Ex tb IIIC T80°C Db, 50–400 W, IP66/IK08) — because methane and coal dust create hazardous zones. Surface sites run on GC high-bay, ZT high-mast floods and TopGo light towers.
A mine is not one lighting problem. Below ground, the constraint is certification: every luminaire in a classified heading must be rated for the gas group and dust group present, and inspectors check the certificate before energising. On the surface, the constraint is scale: haul roads, stockpiles and ROM pads need high-mast floods, workshops need high-bay light, and temporary faces need towers that move with the operation. Iway supplies both scopes from one factory, with the Ex documentation and photometric files EPC contractors need at handover.
Underground Mining Lighting — ATEX/IECEx Explosion-Proof Fixtures
Underground workings, drive headings and hazardous chambers are classified for combustible gas (Zone 1/2) and combustible dust (Zone 21/22). The ROBUS explosion-proof families carry Ex db IIC T6 Gb / Ex tb IIIC T80°C Db certification, sealed die-cast housings and tempered-glass optics — flameproof enclosures that contain any internal ignition so it cannot reach the mine atmosphere.

Matching the Fixture to the Mine Area
The specification question we get from mine engineers is which fixture belongs in which area. This is the mapping we apply on site layouts, followed by a free lux-layout with IES files so uniformity (+/-5%) is verified before installation.
| Mine area | Fixture family | Why this family |
|---|---|---|
| Underground headings, hazardous chambers | ROBUS EX02-A / EX02-B (50–400 W) | Ex db IIC T6 Gb / Ex tb IIIC T80°C Db certification, IP66/IK08, 30–120° beam options for drive widths |
| Underground tunnels, confined drives | ROBUS EX01-C (50–120 W) | Compact flood, 120° beam, same Ex certification in a smaller envelope |
| Workshops, crusher bays, conveyor gantries | GC UFO high-bay (100–300 W) | Up to 180 lm/W, IP65/IK10, DALI and sensor control, emergency battery-backup options |
| Haul roads, stockpiles, ROM pads | ZT181 / ZT143 high-mast floods | 200–1000 W, up to 178,000 lm, 19 kV surge, anti-glare visors for 20–40 m masts |
| Temporary faces, no grid connection | TopGo 70V light towers | 33,000–105,000 lm, 6.0 m mast, zero-emission solar-hybrid — deploys without a diesel genset |
Send the area-classification study, site plan and target lux; we return a matched fixture schedule, IES photometric files and a DIALux evo simulation. Lux levels and fixture counts are quoted per project — we do not publish generic mine lux figures because the right level depends on the task area.

Frequently Asked Questions
Concise, citable answers — written so AI search engines can quote them directly.
What lighting do underground mines need?
Underground workings are classified hazardous areas — methane, coal dust and other combustible atmospheres — so fixtures must carry ATEX (2014/34/EU) or IECEx certification matched to the zone: Gas Zone 1/2 and Dust Zone 21/22. Iway supplies the ROBUS range (EX01-C, EX02-A, EX02-B) rated Ex db IIC T6 Gb / Ex tb IIIC T80°C Db, 50–400 W, IP66/IK08, with documented certificates for inspection. Lux levels and fixture counts are quoted per project against your area-classification study.
ATEX or IECEx — which certification for a mining project?
ATEX is the EU legal framework (Directive 2014/34/EU) required for equipment placed on the EU market; IECEx is the international scheme based on IEC 60079 standards that lets one certificate be recognised across many countries without re-testing. Specify ATEX for European projects and IECEx, often alongside local approvals, for projects in the Middle East, Latin America, Africa and Southeast Asia. We supply fixtures with the correct Ex rating and documentation for your target market.
How are surface mine sites — haul roads, stockpiles, workshops — lit?
Surface operations combine three layers. High-mast floods (ZT181, 200–1000 W, up to 178,000 lm, IP66/IK08, 19 kV surge) cover haul roads, stockpiles and ROM pads from 20–40 m masts. GC UFO high-bay families (100–300 W, up to 180 lm/W, IP65/IK10) light workshops, crusher bays and conveyor gantries at 4–15 m. TopGo zero-emission light towers (33,000–105,000 lm, mast to 6.0 m) cover temporary task areas where there is no grid. We return a free lux-layout so each area hits its target uniformly (±5%).
Can mining lights survive vibration, dust and temperature swings?
The ROBUS fixtures are built for exactly that envelope: sealed die-cast aluminium housings with zinc-rich powder coating, tempered-glass optics, IP66 ingress and IK08 impact ratings, LUMILEDS LEDs and SOSEN drivers, 50,000-hour rated life and a 5-year warranty. Working temperature is −35 °C to +50 °C (EX02 up to +55 °C, with −40 °C on request) for high-altitude and cold-climate sites. Surface GC and ZT families carry the same IP66/IK08–IP65/IK10 sealing philosophy.
What documentation comes with a mining lighting order?
Every Ex-certified order ships with the ATEX/IECEx certificate and fixture markings so EPCs and inspectors can verify compliance before energising. Projects also receive IES photometric files and a DIALux evo simulation, and samples average 3–7 working days. CE, FCC and RoHS compliance documents are supplied per order under ISO 9001 controlled production.
Do you supply mining lighting under OEM/ODM programs?
Yes. Iway manufactures in Shenzhen under ISO 9001 controlled production. OEM/ODM covers voltage and plug options for your market (AC100–277 V and 100–480 V multi-range on the ROBUS range), CCT and driver selection, beam angle, private-label branding and SKD/CKD programs for distributors and EPC contractors. Orders ship on EXW, FOB or CIF terms with consolidated freight.
