High Strength White Reinforcement Polyester Geogrid For Mining
High strength polyester mine geogrid is made of high modulus and
high strength continues PET filaments which are warp knitted and
bundled together as it's body and then coated with fire retarding
and static conducting material. It is one new type mine supporting
wire mesh and a good substitute for metal mesh, plastic mesh,
plastic steel mesh and other traditional products.
Mining Grid is made from high tenacity polyester yarn, coated with
a flame resistant, antistatic coating. mining grid is manufactured
in a range of tensile strengths, from 20KN/m to 1200KN/m. The wide
range of the mining grid product line allows mines and quarries to
costomize to fit their need. With the easily application, mining
grid is widely used in mining engineering, underground and tunnel
engineering. Such as longwalls and highwalls, and other fire proof

Mine grid technology in coal mine face moving and withdrawing:
Install hold hoop,winch,hanging pulley 1~2days before laying the
mesh;at first,check whether direction of the mesh into the working
face is right or not when transport it and make sure that the mesh
could be spread out in the direction of supports' sides;before
paving,at 100-200mm from the front end of each group of
supports,insert a bolt,then press the steel frame on;before spead
the mesh,make manual wench’s free end go through the bottom of the
mesh and hang the steel string to the bolt on the roof;cut off the
binding mesh belt by shears,then spread the folding part out,and
lift up the mesh edge by manual power or single prop to fix with
bolts;then connect mesh edge with steel frame by iron wire at every
300mm intervals.After spreading,use manual winch to hang the mesh
to the below of front frame;when cutting coal,pull the flame one
time after cutting the length of a machine body;before pull the
frame,put down the mesh,and ram even-numbered supporting face guard
till roof guard to support the mesh;next pull odd-numbered
supports,after pull them all,withdraw the even-numbered supporting
face guard one after another,then move the machine.Following this
method spread mesh to the roof guard in the whole workina face.
Polyester geogrid supporting technology in roadway excavation
Take blasting driving as an example:after heading face blasts,lift
up the front canopy to the front,pave the mesh in time and make the
two ends of the mesh fall down along the two sides of roadway
evenly.After harrowing,insert the bolts into the roof plate and fix
up the steel frame,then pave the mesh edges with iron wire.The
length of overlay of the connected mesh should be more than 100mm,and the connection joints distance should be less than 200mm;then brush the sides of
the roadway with pick,insert coal anchor,pave the mesh along the
roadway and connect with the falling mesh from the roof plate.According to the
height of the roadway,pave one or two pieces of mesh on the coal
slides.If the roadway back has mesh bags,rip open and make the
ballasts out,then reconnected with iron wire.
