High-Strength Polyester Geogrid For
Mining
High-Strength Polyester Geogrid For Mining are especially for underground mine and tunnel
applications. The grids have an integrally formed structure with high tensile strength on MD and TD
directions. The Grids are
manufactured from special formula with flame-retardant polymer.High-Strength Polyester Geogrid is a
new type of resin fiber polymer net material, which is
bundled and woven into a matrix with high modulus and high strength polyester filaments. The surface
of the matrix is coated with a flame-retardant conductive layer. Electrostatic coating is used to
replace metal mesh, plastic mesh, steel-plastic mesh, and strapping mesh. Start laying before
stopping mining at the working face, and adopt the synchronous online technology for overall laying,
simplifying the finishing process. The mesh can be prefabricated with different strengths and
specifications according to the working surface conditions. It has technological innovation
significance for improving the withdrawal efficiency and safety of fully mechanized mining face,
especially for the withdrawal under difficult conditions such as long standing time after the end of
the face or water on the roof.

Product Content
The product can be widely used in roadway roof protection, side protection and working false roof. The
plastic fencing mesh for underground coal mines is characterized by softness, light weight, high tensile
force and high knot strength. The polyester mine grille per square meter is only about 1KG, and the weight
of the same metal mesh is more than 10 times that of this product. The minimum tensile strength per square
meter is 40KN, and the maximum tensile strength can be 1000KN, which is incomparable to the strength of
other metal mesh and its polyester fiber reinforced plastic mesh. Acid and alkali resistance, cold
resistance, corrosion resistance, moisture resistance, no static electricity, good flame retardant
performance, and the buried pressure performance in the well remain basically unchanged. Scope of
application: False roof protection for underground coal mining face, temporary and permanent support of
coal mine bolting and shotcrete roadways and tunnels, and can also be used for other mine roadway
engineering and underground civil engineering.
performance：high tensile strength;high tear-resistant;strong combination with gravel and soil
Attention:
1.When the product is found to be cut by a sharp tool during use, it can be used after partial
reinforcement. The reinforcement method is the same as the tie method of the mesh connection.
2.If the product has been stored for a long time or the storage environment temperature is too high,
resulting in large-area deformation of the product or severe bending of the ribs, the product should be
suspended from use, and the mechanical performance test should be passed and the product can be used after
it is qualified.
3.In the use of bolt roadway support, the size of the pallet of the outer end nut of the bolt should be
more than 2 times larger than the grid size.
