PRODUCT DESCRIPTION
Mining support mesh is played an important role for supported and protected safty productio, avoided the accident occurrence and participated in mine rescue in tunnel of mine and coal, It has many mesh type because of difference international standard.It is fitted by anchor.
Coal and mine mesh is divided coal and mine support chain link mesh, warp and weft mesh, coal and mine support anchored reinforced mesh.
Coal and mine support chain link mesh is classified to coal and mine support diamond mesh, galvanized diamond mesh,mine support mesh, and galvanized chain link mesh.
1. Coal and mine support chain link mesh
Material of Coal and Mine support chain link mesh:
a. High quality low carbon steel wire
b. Galvanized wire
c. PVC coated wire
Weaving and characteristics:
a. Crochet made, mesh uniformly, mesh surface flat and beautiful.
b. Width of mesh is wide, wire diameter is thick, it isn't easy corrosion and long service life.
c. High tensile strength and tenacity, especially, PVC chain link mesh has anti-static characteristics.
Application of Coal and mine support chain link mesh:
It is applicated two sides reinforcement and protection, roof protection,false roof ideal material for the tunnel foundation protection of coal and mine.
Feature:
Galvanized chain link mesh is crocheted to be diamond shape, even if a piece of wire is broken, it can't affect other parts of the whole mesh. It solved the problem of easy loose and sagging on the roof protection when using coal and mine support and protected.
The specification of coal and mine chain link mesh as below:
