Can coal stored in high water content spontaneously combust

Can coal spontaneous combustion be prevented in high-pressure water environment?

However, for the coal in the high-pressure water environment, the changes in the physicochemical properties and spontaneous combustion characteristics have been neglected in this process, which increases the difficulties in the prevention of coal spontaneous combustion.

Does water immersion pressure promote spontaneous combustion of coal?

The results showed that elevated water immersion pressure promoted the spontaneous combustion tendency of coal, and the composite judgment index of coal decreased to 521.1. Coal immersed in pressurized water entered the stages of oxygen-absorbing oxidation and thermal decomposition earlier than coal immersed in atmospheric pressure water.

When is spontaneous combustion of coal more likely?

Spontaneous combustion of coal is more likely during and after mining, especially when exposing coals. This tends to be more of a problem in lower seams.

Does pressurized water influence oxidation and spontaneous combustion of coal?

To date, there is substantial research on the oxidation characteristics and spontaneous combustion characteristics of coal immersed in water at atmospheric pressure, but the research neglects the influence of the pressurized water environment.

What causes coal to self-heat and spontaneous combustion?

If this heat is not adequately dissipated, it can cause the coal to heat up further, leading to self-heating and eventual spontaneous combustion. The rate of oxidation increases as the temperature rises, creating a feedback loop that can result in the coal igniting. What factors contribute to coal self-heating and spontaneous combustion?

Are coal mines liable for spontaneous combustion?

To provide a better understanding of the spontaneous combustion phenomena, the prediction of the spontaneous combustion liability in coal mines using reliable testing methods were reviewed, and relationships between the intrinsic and extrinsic properties of coal and coal-shale were established.
