Six Queensland coal mine contraband incidents prompt statewide safety alert

Incident Overview

Six contraband incidents at Queensland underground coal mines have prompted a statewide safety alert, with the mine-safety regulator warning that one spark could trigger a fire or explosion. No injury was reported in the source material.

7NEWS reported on 11 September 2026 that Resources Safety and Health Queensland (RSHQ) had confirmed six contraband incidents across different underground coal mines during the previous five months. Two incidents allegedly involved workers using vapes underground, after more than a decade without a reported case of that kind. The report highlights the need for workers and mine operators to understand serious ignition risks. Workers injured in workplace incidents may wish to obtain advice about workers compensation options.

Workplace, Location and Time

The incidents occurred across underground coal mines in Queensland. The source report did not identify the individual mines or the dates of each incident, but described the pattern as a recent rise in dangerous items being taken below ground.

Workers and Safety Risk

RSHQ Chief Inspector of Coal Mines Jacques le Roux warned that ignition sources are particularly dangerous in methane-rich underground environments. Coal dust can also burn, creating the potential for a fire or explosion if a spark or flame is introduced.

The statewide safety alert reminded mine workers that vapes, e-cigarettes, lighters, matches, smoking materials, mobile phones, smart watches, digital watches, electronic car keys and other devices capable of creating a flame, spark or electrical arc are prohibited underground.

Injuries and Immediate Outcome

The 7NEWS report did not identify an injury, fire or explosion resulting from the six incidents. It reported that investigations remained ongoing, while the regulator focused on preventing a contraband item from becoming an ignition source in an underground mine.

Testing by RSHQ’s scientific arm, SIMTARS, found that vapes can reach temperatures above 250 degrees Celsius. Damaged or overheating devices were also capable of generating more than 100 times the energy needed to ignite gas in an underground mine.

Regulator Response

RSHQ urged workers to check their pockets and bags before going underground. It also called on mine operators to strengthen search procedures and review their systems for controlling contraband.

The regulator said the recent incidents were being investigated. The safety alert was issued while those investigations continued and while operators reviewed the risks associated with ignition-capable devices.
