This study takes the proposed pipeline of Qianjiang- Shaoguan section which affected by steeply inclined goaf in Chashan mining area as the research background. The influence of steeply inclined goaf on the pipeline were studied from the completion of mining and the mining process.Weanalyzed the influence of surface deformation and movement of goaf on gas pipeline, gave a preliminary evaluation method of pipeline safety, and used probability integral method to predict and evaluate pipeline safety in steeply inclined goaf site. Therefore, it is of great significance for the safe operation of pipelines to study the law of pipe- soil interaction and deformation properties in the goaf of steeply inclined coal seam.
