protection mining grid for supporting

Safety Net Introduction

Safety net is made of high-modulus and high strength long polyester fiber which is warp-knitted and bundled together as its body and then is coated with fire retarding and static conducting matetial.It is a kind of new type mine supporting mesh and a good substitute for metal mesh,plastic mesh,steel-plastic mesh and other traditional supporting material.

Safety Net for underground coal mine/ faking supporting

The product has the following features:High strength,light in weight,easy construction,acid and alkali resistance,corrosion resistance,fatigue resistance,low and high temperature resistance,aging resistance,long life,fire retarding,static conduction. 

Safety Net Application

Coal mine face moving and withdrawing,fake ceiling supporting in stoping face,anchoring and shotcreting tunnel supporting,excavation supporting,slicing supporting,surfaced coal mine slope protection, and other civil engineering.

1. Safety net application in working face slicing

High strength polyester mine gird has been ever applied as fake roof in thick seam slicing and wall and roof supporting in the withdrawing of fully mechanized mining working face in Fengshuigou coal mine of National Power Inner Mongolia Plingzhuang Engergy Stock Company Ltd.

2. Safety net in roadway excavation working

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 conection 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 conect 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.
