Comprehensive Solutions For The Application Of "Polyethylene (PE) Pipes For Underground Coal Mines" In Underground Coal Mines

The working environment in underground coal mines is complex and dangerous, imposing extremely strict requirements on the performance of various types of pipes. Jianlong's specially produced polyethylene (PE) pipes for underground coal mines, with their outstanding characteristics, provide reliable and efficient solutions for various key applications in underground coal mines, such as gas drainage, positive pressure ventilation, negative pressure ventilation, water supply and drainage, and shotcreting.

PE pipe performance meets downhole needs

Light weight and easy installation

The density of polyethylene pipes for coal mines is small, and the unit weight is about 1/8 of steel pipes and 1/3 of glass fiber reinforced plastic pipes.

Therefore, polyethylene pipes for coal mines are not only easy to transport and install, but also can greatly reduce the labor intensity of workers when used underground and improve work efficiency.

Corrosion resistance and no scaling

Polyethylene pipes for coal mines have strong corrosion resistance and no scaling, and are particularly suitable for conveying high-sulfur water and water containing calcium, iron and other ions.

It greatly saves the cost of anti-corrosion and descaling, and the service life is much higher than that of steel pipes, with high comprehensive economic benefits.

Good anti-aging and anti-rapid cracking performance

Polyethylene pipes for coal mines have good anti-aging performance, are not easy to become brittle at low temperatures, and have good anti-rapid cracking performance; they have good toughness and can effectively absorb impact energy; the bending amount is moderate. Under special working conditions such as underground coal mines where geological subsidence and other phenomena occur from time to time, polyethylene pipes for coal mines can effectively avoid fracture accidents.

Flame retardant and antistatic

The antistatic and flame retardant components of polyethylene pipes for coal mines are evenly distributed in the pipe body, so the antistatic and flame retardant performance indicators will not be affected by long-term use.

Self-lubricating property

The inner wall of polyethylene pipes for coal mines is smooth, the resistance is small when conveying fluids, and the roughness is much smaller than that of steel pipes and glass fiber reinforced plastic pipes. Under the same conditions, the conveying capacity can be increased by 30%.

Good wear resistance

The wear resistance comparison test of polyethylene pipes for coal mines and steel pipes shows that the wear resistance of polyethylene pipes for coal mines is 4 times that of steel pipes. In the field of coal transportation, polyethylene pipes for coal mines have better wear resistance than steel pipes.

Impact resistance

The low-temperature brittle temperature of polyethylene is extremely low and can be used at lower temperatures.

High toughness

Good flexibility and strong resistance to geological subsidence; elongation at break exceeds 300%.

Easy to connect

Hot melt connection, pipe clamp connection or flange connection are used, which is convenient and fast to construct, reducing installation costs and shortening installation cycles.

Multi-purpose Application Solutions

Gas Drainage

Gas drainage is a crucial part of coal mine safety production. The smooth inner wall of the PE pipes can effectively reduce the flow resistance of gas and improve the drainage efficiency. Their corrosion resistance ensures that they will not be corroded and damaged when in long-term contact with gas and its impurities, guaranteeing the stable operation of the gas drainage system, reducing the gas concentration, and preventing gas accidents.

Ventilation System

In positive pressure ventilation and negative pressure ventilation, the PE pipes are lightweight, making them easy to install and maintain. They can significantly reduce the self-weight of the ventilation pipeline system and lower the requirements for the support structure. At the same time, their good airtightness ensures the ventilation effect, providing sufficient and clean air for the underground workers and maintaining a good working environment.

Water Supply and Drainage

The water supply and drainage system in underground coal mines is of vital importance. The corrosion resistance of the PE pipes makes them less likely to scale and clog when transporting mine water containing impurities and corrosive substances, ensuring smooth drainage. In terms of water supply, their good sanitary performance ensures that they will not contaminate the water quality, guaranteeing the safety of production and domestic water use underground.

Shotcreting Operation

In the shotcreting operation for the support of coal mine roadways, the PE pipes can be used as conveying pipelines. Their strong wear resistance enables them to withstand the scouring of the high-speed flowing shotcrete materials, ensuring the continuity and high efficiency of the shotcreting operation, improving the quality of roadway support, and ensuring the safety of underground operations.
