Gas explosion is the most common accident in coal mine accidents. In order to ensure the safe production of coal mines, all units and departments pay great attention to the study of gas. At present, the most common measure in coal mine production is to pump gas from special gas. To ensure the safety of mine operations. Gas pipelines are dedicated pipelines for the extraction of gas from coal mines. The performance of gas pipelines directly affects the safe production of coal mines. It can be seen that the performance of gas drainage pipelines has a major impact on the safe production of coal mines.
