Abstract
The utility model discloses a high strength compound network used in mines, comprising a basal body weaved by alkali free or medium alkali glass fiber and high strength polyester yarn lashing wire and an inflaming retarding and static conducting coat which is arranged on the surface of the basal body. The utility model has the advantages as bellow: 1. high anti expansion performance and air tightness, oil stain resistance, soda acid and sulphurets corrosion resistance, humidity resistance, oxidization resistance and long service life; 2. light weight, easy transportation and construction, low labor intensity and quick construction; 3. inflaming retarding, static conduction, extremely high strength and safe use in mines; 4. lower use cost, better overall social benefits, while compared with currently similar products.
Description
Technical field
The utility model relates to the support material under a kind of coal mine.
Background technology
In the digging laneway and tunnel exploitation that layering is mined, adopt wire lath usually as supporting.Though wire lath intensity is higher, its corrosion resistance is poor, and easily oxidized, and especially in comparatively moist environment, after very fast usually oxidized the getting rusty of wire lath, its structural strength reduces greatly, thereby injures down-hole constructor's safety.
The utility model content
At the problem of above-mentioned existence, it is a kind of corrosion-resistant, anti-oxidant that the purpose of this utility model is to provide, and has the compound net of high-intensity mining high strength.
For achieving the above object, the compound net of a kind of mining high strength of the utility model comprises: the matrix that is formed by alkali-free or medium-alkali glass fibre and the braiding of high tenacity polyester fiber silk lashing wire, the coating that being coated with one deck at this body upper surface can be fire-retardant, lead static.
Further, the material of described coating is: water-based or oiliness pvc resin fire-retardant, electrostatic-conducting coating, or water-based or oiliness chloroprene rubber fire-retardant, electrostatic-conducting coating.
The utlity model has following advantage:
1, the burn into humidity of high anti-rising property, high-air-tightness, oil resistant dirt, acid and alkali-resistance and sulfide, anti-oxidant, long service life;
2, in light weight, be convenient to transportation and construction, reduce labour intensity, construction speed is fast;
3, have fire-retardant, lead static and high intensity, the down-hole is safe in utilization;
4, present like product (as wire lath), use cost is low, has good comprehensive social benefit.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is the structural representation of matrix among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises: the matrix 1 that is formed by alkali-free or medium-alkali glass fibre and the braiding of high tenacity polyester fiber silk lashing wire, the coating 2 that being coated with one deck at this body upper surface can be fire-retardant, lead static; Wherein, the material of coating 2 can be water-based or oiliness pvc resin fire-retardant, electrostatic-conducting coating, or water-based or oiliness chloroprene rubber fire-retardant, electrostatic-conducting coating.
When the utility model uses, specific as follows:
1, when in anchor band net supporting tunnel, colliery, top board uses " M " steel band of model and anchor dish to compress the compound net of high strength, and uses full thread steel equal strength anchor rod to hang; Two help to adopt full thread steel equal strength anchor rod+anchor dish to compress the compound net supporting of high strength, twist the jail with 14# iron wire (or same strength materials) every 150～200mm between net and the net.
2, in the interim and permanent support in colliery bolting and shotcrete roadway and tunnel with anchor pole and anchor dish fixedly behind the compound net of high strength sprayed mortar add strong supporting, use 14# iron wire (or same strength materials) stubborn firm between net and the net every 150～200mm.
Claims (2)
1, the compound net of a kind of mining high strength is characterized in that, comprising: the matrix that is formed by alkali-free or medium-alkali glass fibre and the braiding of high tenacity polyester fiber silk lashing wire, the coating that being coated with one deck at this body upper surface can be fire-retardant, lead static.
2, the compound net of a kind of mining high strength according to claim 1 is characterized in that the material of described coating is: water-based or oiliness pvc resin fire-retardant, electrostatic-conducting coating, or water-based or oiliness chloroprene rubber fire-retardant, electrostatic-conducting coating.
