Queensland’s mining safety regulator has issued a warning to coal mine operators and workers following an alarming spike in contraband entering underground operations this year.
Resources Safety and Health Queensland (RSHQ) revealed it has received six separate reports of unauthorised ignition sources in underground coal mines so far in 2026.
The illegal items detected include two vapes, two unauthorised watches, a mobile phone, and smoking materials.
The sudden surge marks a drastic escalation in non-compliance. RSHQ records show only a single report of underground contraband was recorded between 2000 and 2025, a 2012 incident involving smoking materials.
The regulator warned that contraband presents a catastrophic threat due to the presence of methane gas and combustible coal dust in underground environments.
A single spark, open flame, or battery failure can instantly trigger a massive fire or explosion, endangering dozens of lives.
RSHQ emphasised that lithium-ion batteries found in vapes, smartwatches, and mobile phones pose severe risks even when turned off.
If dropped, crushed by heavy equipment, or short-circuited under mechanical stress, these batteries can fail catastrophically and generate extreme heat or electrical arcs.
Mine operators, Site Senior Executives (SSEs), and supervisors are being urged to immediately review ignition source controls, visitor access protocols, and worker training.
RSHQ advised sites to audit their search procedures to ensure they include both routine and random checks across all shifts, contractors, and staff.
Workers are instructed to thoroughly check their pockets, personal bags, and belongings before heading underground, and to declare any prohibited items immediately.
RSHQ reminded all personnel that failing to comply with Queensland’s coal mining safety legislation carries severe penalties, including immediate termination of employment, site disciplinary action, or criminal prosecution.
Underground investigations into the recent incidents remain ongoing.
