Abstract: In the Gequan coal mine, such geological structures as folds and faults are extensively developed, and the geological structures are more complex on its south limb than on its north limb. A study of gas geology on the south limb indicates that the geological structures are leading factors bringing about the abnormity in gas effusing. Some suggestions and measures are given for forecasting the abnormal gas effusing.
