Abstract: In order to improve the resource recovery rate of coal and alleviate the problem of tight mining and tunnelling
replacement, the technology of gob-side entry retaining by roof cutting and pressure relief was adopted in the 5-200 working face
of Fangshan Dianping Coal Mine. The on-site application results show that the deformation of the roadway after roof cutting and
pressure relief is significantly reduced, and the comprehensive production cost is reduced by 10% to 20%, resulting in significant
economic benefits.

Key words: gob-side entry retaining; roof cutting and pressure relief; coal mining without pillars
