Abstract: In terms of improving the recovery rate of coal resources and the speed of roadway excavation, gob side entry retaining
is an effective method. This paper introduced the parameter design in the process of entry retaining with roof cut-out pressure relief
in A Coal Mine, and analyzed the construction process of roof cut-out pressure relief.

Key words: coal mining; gob side entry retaining; roof cut-out pressure relief; mining design
