| Abstract: | In the mined-out areas,theoretical and numerical simulation comparative analysis on gas flow law with U+L ventilation and Y ventilation are conducted.The Y ventilation benefits are indicated by gas control effect comparison of U+L ventilation of fully-mechanized mining face in the early stage and Y ventilation of gob-side entry retaining in the later stage of No.24202 Shaqu Mine.Finally,combined with the actual situation,the suggestions for future are presented. |
