Spontaneous combustion is a serious safety hazard in underground coal mines, particularly in mined-out areas (e.g., gob). It is estimated to be the cause of more than 20% of coal mine fires. Pressure balancing is a ventilation technique that can be used to reduce or eliminate the ingress of oxygen t...

Secondary Li-ion batteries are considered the most sustainable power supplies for electric vehicles (EVs). With the extensive implementation of EVs, we are starting to find an expanding number of safety accidents triggered by Li-ion batteries in EVs globally. Battery EV fire produces intense heat, s...

Lithium-ion (Li-ion) batteries are finding more use as power sources in the mining industry. However, they are known to pose significant fire and explosion hazards. When a Li-ion battery is exposed to excessive operating conditions, its internal temperature may exceed a normal operating range, allow...

The evolution of major coal oxidation and resulting sponcom incidents are sudden and may result in catastrophic negative safety outcome or result in the withdrawal of persons and closure of longwall panels/mines. Historically, experiences of highly gassy longwall workings in Australian Goonyella Mid...

An experimental investigation of temperature decay and maximum smoke temperature beneath an underground mine drift (54 m long, 2.6 m wide, and a height of 3.2 m) was carried out to examine the effect of ceiling smoke extraction on fire evolution in an underground mine. A single non-centralized smoke...

Detecting the development of explosive methane–air mixtures on a longwall face remains a difficult task. Even when atmospheric monitoring systems and computational fluid dynamics modeling are used to inspect methane concentrations, they are insufficient as a real-time warning system in crucial are...
