| Abstract: | In order to study the rapid and safety equipment withdrawing technology of 61101 work face in Tangjiahui Coal Mine，the deformation and failure of surrounding rock of withdrawal passageway were simulated by numerical simulation with the pre-driven and the exist-driving conditions，the scheme that combined anchored cable and chock support was proposed in this paper.The laws of strata behaviors for withdrawal technology were summarized by field application，which provides a practical and theoretical basis for further optimizing the support parameters of withdrawal passageway. |
