In order to analyze the impact hazards during the recovery of the coal column recovery isolated island face in the south wing of the 707 mining area of Senbao Coal Industry, the likelihood index method and engineering analogy method were used. First of all, research and collection of the geological and technical conditions of the mining recovery was conducted, with analysis on the basis of a full grasp of basic data. The analysis by the likelihood index method showed no impact hazard, without impact ground pressure. The influence of five key factors on the occurrence of shock ground pressure was analyzed by the engineering analogy method, and it was found that the possibility of each factor inducing shock ground pressure alone was relatively small. Combining the likelihood index method and the engineering analogy method, the face recovery process can be done under the premise of good safety protection and other measures.
