| Abstract: | In view of the conditions of 71 coal seam in Qidong Coal Mine of Wanbei Coal and Electric Power Group Corporation Ltd.,the displacements and stresses of surrounding rock of roadways drove along goaf and with different width coal pillars are simulated by use of FLAC2D software,and the reasonable coal pillar width is determined for roadway driving along goaf between adjacent working surface sectors in 71 coal seam,this provides reference to the determinate of reasonable position of similar roadway driving along goaf. |

| Keywords: | Driving roadway along goaf Width of coal pillar FLAC2D Numerical simulation |
