Abstract Based on the exploration data, mining and excavating engineering exposed data and related test results of Hegang Mine in Jining, the hidden disaster-causing factors including goaf, impact risk and underground water body in the study area were studied in detail by means of field investigation, underground observation and statistical analysis. Nine hidden disaster-causing factors affecting the future production of the mine were identified, three hidden disaster-causing factors of which could be excluded. Combined with the characteristics of each hidden disaster-causing factor, targeted prevention and control measures were proposed.
