| Abstract: | Taking gob-side roadway engineering in the mining roadway of 3112 isolated working face,Dongfeng Colliery as the background,the coal pillar width is determined as 8.28 m by theoretical calculation,and the reasonable reserved width of coal pillars in the 3112 working face as 9 m by UDEC numerical simulation,which proves that industrial tests have achieved good results. |

| Keywords: | isolated working face gob-side roadway coal pillar width stress distribution |
