Type: article
Abstract: As one of the main energy sources in China, it is very important to ensure the safe production of coal. Aiming at the problems of air leakage, gas accumulation, large dust and spontaneous combustion of coal seam in 1027 gob-side entry retaining working face of Jiegou Coal Mine in Anhui Province, the technical measures of " one ventilation and three preventions " are adopted. Through the use of Y-type ventilation system, thin spray sealing technology of gob-side wall and three kinds of fire prevention and extinguishing technology, the safe production of gob-side entry retaining working face is ensured, which provides technical and practical experience for the " one ventilation and three preventions " work during the safe mining period of gob-side entry retaining working face.
