Description
Shantengyue Jiang and Mo Zhang offer a 2026 modeling paper on gas moving through hot, cracked coal deep underground. Older work often treated crack roughness in rough terms, which made danger forecasts for mines less useful. Their model links heat, water pressure, rock strain, and crack shape in one system, using a single roughness score to connect surface bumps with how easily gas flows.
Checks against real records from a Liupanshui coal face and from a gas well support the model. Warmer coal and smoother cracks both let gas move faster and raised pressure and ground shift in the tests. Mine teams can use results like these to judge where gas may gather before it becomes a hazard.
