Coal Mining of High-Strength Polyester Fiber Geogrid

Coal mining polyester fiber reinforced plastic mesh fake ceiling is made of high modulus, high strength polyester filament warp knitted and bundled together as the base body, and coated with flame retarded, static conductive material. It can replace the net ceiling intertwined with bamboo splint and metal wire. The product has the excellent property in acid and alkali-resisting, anti-aging, flame retarded and static conductive. Furthermore, it has low cost, long life length, high breaking strength. Therefore, it can be widely used in tunnel for its protective ceiling, side protection and working fake ceiling

Product Feature

With the property of solid and soft, light in weight and high in breaking strength, the consumption of the fake ceiling is only around 1 kg per meter, while the corresponding metal ceiling will be about 32 kg per meter. The breaking strength can be ranged from 40kn to 800kn. The property is outstanding, compared with the metal net and other high strength mining nets for the same use.

Good acid and alkali-resisting, anti-corrosion; No friction static, excellent flame retarded and static conductive property. The property is unchanged when the fake ceiling is buried in mine; By the contrast, the metal net will be corroded, and the breaking strength will be dropped greatly.

Range of Use

The fake ceiling supporting facilities in mining work section, the anchoring and shotcreting tunnel, the temporary and permanent supporting in tunnel, other mining tunnel project, underground building project.

Economic benefits

With the use of coal mining polyester fiber reinforced plastic mesh fake ceiling, wall rock will be protected. The collapse of flank wall in tunnel, the falling off of coal gangue and roof collapse will be effectively avoided. The safety of tunnel be greatly improved and safety incident will be greatly diminished.

Ventilating resistance in tunnel can be effectively dropped, and the power consumption can be saved. The fake ceiling can be recycled and reused when it is for temporary supporting in the work site of driving and mining underground.

The fake ceiling has the advantage in light weight, good acid and alkali-resisting, low cost, easy laying. The workload for linking the fake ceiling is also reduced.

The general grid size: 40mm*40mm, 50mm*50mm. The size can be changed according to buyer's demand. The general color is cream-colored, and it also can be changed with the demand of buyer.

Method of Application

In mining supporting tunnel, the technical requirements for laying metal protective net can also adopted in the laying of coal mining polyester fiber reinforced plastic mesh fake ceiling. It should be firmly pressed and fastened by M type steel belt and anchor wheel, hung up and pulled in high tension with the high strength deformed steel bar. The overlapping width should be over 200mm on the linking position.
In the case of permanent supporting in anchoring and shotcreting tunnel, the technical requirements for laying metal protective net can also adopted in the laying of coal mining polyester fiber reinforced plastic mesh fake ceiling. To solidify the supporting, it will be more effective if concrete is sprayed after fixing the fake ceiling with anchor rod and anchor wheel.

In the case of temporary supporting at the work section of driving and mining underground, the fake ceiling has more advantage, compared with other metal nets. It is light in weight, can be easily folded and used at work site.
