Abstract: Taking 5105 large cross-section gob-side entry in Tashan coal mine as engineering background,by using the on-site measurement method,the variation relationships between roadway surface displacement,end anchor bolt axial force and the distance to coal face were researched in mining process.The results show that under the common influence of mining face and adjacent lateral residual abutment pressure,the advanced abutment pressure influence range of large cross-section gob-side entry is increased;the convergence amount of roadway sides is much larger than the variation amount of roof and floor in recovery period,the displacement along the gob is larger than the entity coal side displacement.In the mining drastic influence stage,the end anchor bolt axial force fluctuations violently,and the phenomena are completely different with the static pressure roadway.
