Study on the influence of ventilation methods on coal spontaneous combustion in gob-side entry retaining goaf areas

Gong-kuang zidonghua
Under gob-side entry retaining mining conditions, the gas distribution characteristics in the goaf are easily affected by the ventilation methods, making it difficult to accurately identify the locations of coal spontaneous combustion hazards. To address
