Degassing pipe
Gas drainage pipes are specialized pipelines used in coal mines to extract gas from coal seams, surrounding rock formations, and mined-out areas. They pump combustible gas to the surface or to safe zones under vacuum, thereby preventing gas accumulation and explosions. Their primary function is to ensure mine safety; at the same time, the extracted gas can be utilized as a resource—for example, for electricity generation or for domestic gas supply.

Degassing pipe
Gas drainage pipes are specialized pipelines used in coal mines to extract gas from coal seams, rock formations, and mined-out areas. They convey combustible gas to the surface or to safe zones by creating a vacuum, thereby preventing gas accumulation and explosions. Their primary function is to ensure mine safety; at the same time, the extracted gas can be utilized as a resource—for example, for power generation or for domestic gas supply.
Main types and parameters
Material: metal (e.g., steel, steel pipe with a plastic coating), PVC/PE plastic pipe; the metal pipe is resistant to high pressure, while the plastic pipe is corrosion-resistant.
Technical specifications: diameters ranging from 25 mm to 800 mm, wall thicknesses from 2 mm to 30 mm, enabling adaptation to various drainage requirements.
Performance characteristics: the material must be fire-resistant, antistatic, resistant to acids and alkalis, and so on, with a service temperature range of –30°C to 120°C.
Installation and selection
Installation requirements: The pipeline must be suspended level and at a distance of at least 300 mm from the ground, avoid routing it on the same side as the cable, and ensure that water is drained regularly.
Selection calculation: Determine the pipe diameter based on the gas emission volume, wastewater volume, and flow velocity (typically 5–15 m/s).
