Abstract: Loess gully region gob is the only ways for West-East oil and gas pipeline, the risk assessment on oil and gas pipeline traversing gob is a major issue for solving operation of pipelines. It combines with integral method to further make risk assessment on oil and gas pipelines traversing god based on the results of mining subsidence hazard study in loess gully region. The method has proved that it has some guidance on risk assessment of oil and gas pipelines traversing the loess gully region.
