The special drainage pipe for mining is developed for severe working conditions such as underground water discharge, tunnel drainage, and dry drainage. It is made of high-pressure and high-impact HDPE material, which can withstand complex geological pressure and long-term water flow initialization. The overall strength is high, and the toughness is good. It adapts to the complex operating environment of the mine.

The inner wall of the pipe is smooth, non-scaling, non-blocking, high drainage efficiency, and at the same time acid and alkali resistance, mud wear resistance, corrosion resistance, and not easy to age and crack. Using hot melt or flange connection, the interface has strong sealing and no leakage. It can still operate stably in humid, dusty, and frequent vibration underground environments, with long service life and low maintenance costs.

Widely used in coal mine, metal mine, non-metallic mine underground drainage, tunnel drainage, tailings drainage, mine construction drainage and other scenes, is to ensure the safety of mine production, prevention of water damage special drainage pipeline.

• Steel wire reinforced structure, high pressure bearing and negative pressure resistance

  The steel mesh skeleton is compositely reinforced and can withstand pressures up to PN1.6MPa-PN10.0MPa, adapting to high-pressure and negative-pressure suction conditions for underground drainage without pipe explosion or collapse;

• Double protection of inner and outer layers of HDPE, resistant to mineral water and slurry corrosion

  The outer layer is anti-aging and erosion-resistant, and the inner layer is resistant to corrosion by acidic mineral water and tailings wastewater, and is resistant to scaling and medium penetration;

• Resistant to impact and creep, suitable for complex underground drainage conditions

  Resist slow crack growth, resist water flow impact and sediment erosion, and adapt to underground geological subsidence and hydraulic pressure fluctuation deformation;

• Antistatic and flame resistant, meeting mining safety regulations

  It can achieve anti-static and flame-retardant modifications to avoid the safety risks of sparks and static electricity accumulation in underground drainage conditions;

• Steel-plastic combination, both rigidity and toughness

  The strength is higher than that of pure PE pipes, the flexibility is better than that of steel pipes, it can be laid in a bend, and it resists the displacement and vibration damage of underground surrounding rocks;

• High-pressure connection is reliable, drainage is anti-seepage and anti-leakage

  Special high-pressure component connections and tight sealing of the steel-plastic interface prevent mineral water leakage from contaminating the underground environment and are suitable for long-distance drainage pipe networks;

• Lightweight, easy to install, high mining construction efficiency

  The dead weight is much lower than that of steel pipes, which facilitates underground transportation and docking. 50mm-225mm diameter pipes can be customized according to actual working conditions, greatly shortening the construction period of the drainage pipe network;

• Long-term stability and durability, reducing mine drainage operation and maintenance costs

  The service life of drainage in mining areas is ≥30-50 years. It does not need anti-corrosion and frequent maintenance and replacement, reducing investment in maintenance of underground drainage systems.
