Abstract: To address disaster-related problems induced by retained coal pillars, including stress concentration, gas accumulation in the goaf and the upper corner of the working face, and spontaneous combustion of coal pillars, a study on roof-cutting gob-side entry retaining technology for no pillar mining was conducted in the 11309 working face of Fujia’ao Coal Mine. Based on the theory of the “roof-cutting short cantilever beam”, a no pillar mining process using roof-cutting gob-side entry retaining was proposed for Fujia’ao Coal Mine. Through theoretical analysis and numerical simulation, the roof-cutting parameters of the 11309 return airway were designed, and the roof pre-splitting blasting cutting parameters, roof reinforcement support scheme, and strengthened support scheme for the dynamic pressure zone were determined. Field engineering tests were subsequently carried out, and rock pressure monitoring of the surrounding rock of the roadway was performed. The roof-to-floor convergence of the roadway was less than 500 mm, while the side-to-side convergence was less than 350 mm. The results indicate that the application of roof-cutting gob-side entry retaining technology for no pillar mining achieved favorable engineering performance. The deformation of the retained roadway section remained within a controllable range, and the overall retaining effect was satisfactory, thereby meeting the requirements of safe on-site production.
