Abstract: In order to further improve the ventilation safety of the working face, eliminate the hidden danger of gas accumulation in
the upper corner, and increase the coal pillar recovery rate of the working face, Zhangcun Coal Mine proposed the application of Ytype
ventilation system in gob side entry retaining for the 2603 working face through technical research. This paper analyzed the
principle and advantages of the Y-type ventilation system, and discussed the practical application of the Y-type ventilation system
in gob side entry retaining. The actual application results show that the application of the Y-type ventilation system in gob side entry
retaining has solved the problem of gas accumulation in the upper corner, reduced the amount of roadway excavation works,
increased the amount of coal pillar extraction and achieved significant application results.
