Description
Technical field
The utility model relates to a kind of mine and props up protecting wire net with steel wire, belongs to mine safety material technology field.
Background technology
Aspect the mine safety guarantee, a protecting wire net that is widely used carries out safety support to tunnel in the mine and getting working face, to ensure mine and miner's personal safety.Propping up protecting wire net is to use the most general a kind of support material in the mine operation.
At present, in the mine support below main the use several kinds prop up protecting wire net: iron wire rhombus net, welded steel fabric, plastic-steel composite web and plastic wire.
The iron wire mesh grid is to use at present a most general protecting wire net, and this net is to be the rhombus net that the mild steel wire (being commonly called as iron wire) of 300-500MPa is weaved into diameter 2.0mm-3.5mm tensile strength.This web frame is simple, and is easy to process, and low price uses the most extensive in mine support.Iron wire rhombus net is the continuous broken line that iron wire is processed into certain-length, and then many continuous broken line hooks are connected constitutes, and the termination of iron wire is curved hook, the iron wire at edge is hooked mutually prevent to scatter, and whenever throwing the net breaks into a volume according to certain length.The advantage of this net is that processing is simple, and bargh can oneself process.Shortcoming is that the hook on the iron wire selvage can be hooked in or be hooked in other wire gauze with wire gauze self in each link of depositing, load and unload, transport, using.Brought many troubles for stock, loading and unloading, transportation and use.When the diameter of iron wire surpassed 3.5mm, processing was got up also difficult.The compressive strength of this wire gauze is not high, when the monolithic net being linked to be integral body carrying out the supporting operation, needs overlap joint each other between net and the net, and overlapping rate takies 10%-15% of whole protecting wire net approximately, and availability is not high.
Welded steel fabric mainly is used in the mine scale or bigger mine support is pressed in the ore deposit.Welded steel fabric generally adopts diameter 4.0-10mm, and the low-carbon (LC) cold-drawn bar of tensile strength 300-500MPa is arranged in length and breadth, and node is welded.The advantage of this net is: can use thicker material to weld, thereby strength ratio iron wire rhombus net height, it is not yielding to be used for mine support.Exactly because not yielding, the depositing and transporting, stock and carrying for ease of inconvenient rolling; The monolithic size of this net is generally all not too big; So overlap joint is more when construction, length and width all will overlap, and overlap joint has taken 10-25% of whole supporting web area.This in addition net Heavy Weight, cost is high, and price is also more expensive.
The plastic-steel composite web is a kind of novel the protecting wire net that is used for mine that occurred in recent years.This net is to be combined with each other through plastics outside the steel wire about many diameter 0.6mm that are arranged side by side, tensile strength 2000MPa, processes the plastic-steel band, and then the plastic-steel band is woven into net, the net that adopts the plastics weldering to link together and process at the node place of net.Its advantage is that intensity is high, in light weight.Shortcoming is: the node place is through Plastic Welding, and node strength very low (about 200N) is easy to when being used for shaft and drift supporting collapse out at the node place.Next is a getting working face when blowing out, and with the plastics avalanche of Steel Wire Surface, after node collapsed out or plastics come off, steel wire was exposed in the mine malaria easily, and it is disconnected to be easy to rust, loses support action.Thereby the scope of application limitation of this protecting wire net is bigger, only uses in small range, can't popularization and application.
Plastic wire also has use in mine support.Plastic wire has two kinds as the mine support net, and a kind of is plastic mesh, and also a kind of is the plastics geonets.Its advantage be in light weight, price is low.But this net receives the restriction of plastics self character, though tensile strength is bigger, shear strength is lower, is not suitable for the ore deposit and presses supporting big, that need to adopt the shot firing operation environment.Therefore the scope of application of net is also little like this.
in sum, existing various protecting wire nets all in various degree exist some defectives, combination property is not fine, some receives Effect on Performance own, the scope of application receives certain limitation, can't obtain popularizing in an all-round way.Some intensity is not very desirable, is further improved.Propping up protecting wire net is the maximum consumptive material of use amount in the mine, it is estimated that the annual consumption of China is not less than 300,000,000 square metres; It is low to develop a kind of price; Intensity is high, and a protecting wire net easy to use reduces the mine support cost for strengthening mine safety; Alleviate labor strength, improve mine economic profit and have great significance.
The utility model content
The purpose of the utility model is, provides a kind of mine to prop up protecting wire net with steel wire, can make the gauze wire cloth that bearing strength is higher than wire gauze with the manufacturing cost that is lower than wire gauze.Can alleviate simultaneously the weight of a protecting wire net itself, both can improve the bearing strength of a protecting wire net, can alleviate the weight of a protecting wire net again, be convenient to operation, can be used as the substitute products of an existing protecting wire net.
The technical scheme of the utility model
Protecting wire net is propped up with steel wire in a kind of mine, and this protecting wire net is the braided steel wire net, and its mesh is a hexagon, and the straight flange of mesh is that two steel wire strands connect, and hexagonal hypotenuse is single steel wire.
