Silent Gas, Loud Alarm: Dhanbad Coal Belt Shaken by Deadly Leak
In Kenduadih, on the southern edge of Dhanbad’s coal belt, residents say the air turns unbreathable after dark. A carbon monoxide leak linked to the Putki–Balihari colliery area has been blamed for multiple deaths and widespread illness, forcing families to abandon homes built on a landscape shaped and destabilised by decades of mining. The incident, which began escalating in December 2025 and has continued into January 2026, has claimed at least three lives and left dozens hospitalized with severe respiratory distress, nausea, and disorientation.
The latest victim, a resident of Rajput Basti, was rushed to the regional hospital just days ago, underscoring that the danger is far from over. "We sleep with masks on, but the headaches don't stop," said Ravi Singh, a resident. "The ground beneath us is burning, and now the air is poisoning us".
The leak is not an isolated industrial accident but a symptom of a century-old wound. The Jharia coalfield is home to underground fires that have raged since 1916. According to experts from the Central Mine Planning & Design Institute (CMPDI), who recently deployed drones for thermal mapping, the leakage is a result of subsidence.
As the coal burns underground, it creates voids. When the land above sinks (subsidence), cracks form, acting as chimneys for lethal gases like CO, which is odourless and colourless, to seep into homes. Bharat Coking Coal Limited (BCCL) ,which has recently launched a sucessful IPO, has attempted to contain the crisis by injecting liquid nitrogen into boreholes to displace oxygen and cool the fires, but these are stopgap measures against a geological juggernaut.
Shri Sanjeev Pathak, Advocate and social worker of Bokaro district, says , 'The burning coal mines of Jharia area are time boms.It can explode anytime." This sentimate is echoed by locals also.They are spending sleepless nights.They are living under constant threat since decades.
The gas leak highlights the "triple threat" facing Dhanbad’s mining belt:
- Fire: The underground infernos are the root cause. They destabilize the rock strata and produce toxic emissions.
- Collapse: Land subsidence is the most visible risk. In late 2025, incidents of vehicles and even homes being swallowed by sudden craters were reported. The earth, hollowed out by fire and extraction, is fragile.
- Water: While fire grabs the headlines, water inundation remains a silent threat. During monsoons, abandoned mines often fill with water. If a thin wall between an active and an abandoned water-logged mine breach, the result is a flash flood underground—a tragedy that has claimed countless miners' lives in India’s history.
For the residents of Kenduadih, the choice is between a lethal home and an uncertain future. While administration notices urge immediate evacuation, locals are hesitant. "They ask us to leave, but where do we go? The rehabilitation colonies are far, jobless, and often lack basic amenities," argues a local community leader.
As the region grapples with this crisis, safety protocols are more vital than ever for both miners and residents in affected zones:
- Gas Detection is Non-Negotiable: Miners must carry portable multi-gas detectors. For residents in danger zones, CO alarms should be mandatory in homes.
- Know the Exit: In underground mining, maintaining clear, well-lit escape routes and refuge chambers is critical.
- Ventilation Discipline: Never block ventilation ducts. In the event of a leak, move upwind or to higher ground immediately; CO is slightly lighter than air but can mix and linger in enclosed spaces.
- Respect Barriers: Never enter abandoned or "sealed" mine areas. The air inside is often oxygen-deficient or explosive.
