Abstract: The case for small coal pillars along goaf part of the coal resources can not be exploited, so in Xu Tuan 8214 wind lane completely roadway driving along goaf scheme is proposed,then,this paper through the numerical simulation demonstrates the rationality of the scheme. In order to accurately grasp the completely along goaf roadway mine pressure distribution, we arrange at the scene monitoring section and compare with the same conditions roadway driving along goaf with small coal pillar .The results found completely roadway driving along goaf exists asymmetry of mine pressure effect, stress environment is better than small coal pillars along goaf. Finally, this paper puts forward asymmetrical frame reinforcement anchor supporting structure, monitoring results show that deformation of roadway excavation and recovery phase for mine production safety does not affect, supporting effect is remarkable.

Key words: completely roadway driving along goaf, supporting technology, asymmetry mine pressure, roadway deformation
