Abstract

A spacing strip type support false roof web for a coal mine is composed of warp strips, zonal strips, warp binding wires, enhancing strips and staggered binding wires. The spacing strip type support false roof web for the coal mine is characterized in that the warp strips and the zonal strips are vertically arranged in a staggered mode, the staggered positions of the warp strips and the zonal strips are provided with the staggered binding wires, the warp binding wires are arranged inside the warp strips, and the enhancing strips are arranged between adjacent warp strips. The spacing strip type support false roof web for the coal mine has the advantages of being large in strength, reasonable, even and stable in web hole structure, and capable of effectively maintaining surrounding rocks among rock bolts and preventing crushed rock blocks from collapsing and falling, thereby having good performance of impact resistance and concentrated load resistance.

Description

Colliery spacer bar belt supporting false top net

Technical field

The utility model relates to the mining equipment technical field, a kind of colliery of saying so more specifically spacer bar belt supporting false top net.

Background technology

At present, what the coal mine support net generally adopted is the anchor cable net mode, adopt anchor pole, cooperations such as an anchor cable protecting wire net carries out surrounding rock supporting to the tunnel, set up steel band, girder steels etc. strengthen anchor pole, the whole supporting effect of anchor cable, prop up protecting wire net as the important component part of coal mine support member, played and protected table, carry stressed important function, what a protecting wire net of prior art generally adopted is the flexible whole protecting wire net of polyester fiber, but the flexible whole protecting wire net intensity of the polyester fiber of prior art is still on the low side, the force request that can not adapt to heavily stressed coal mine, security incident usually appears in the coal mine easily bigger for geostatic stress, causes bigger economic loss.

Summary of the invention

For addressing the above problem, the utility model has designed a kind of rational in infrastructure, and the colliery that can adapt to the bigger coal mine of geostatic stress spacer bar belt supporting false top net, its concrete scheme is: described colliery is made up of warp-wise band, broadwise band, warp-wise lashing wire, enhancing band, staggered lashing wire with spacer bar belt supporting false top net, it is characterized in that warp-wise band and the setting of broadwise band vertical interlaced, warp-wise band and broadwise band staggered place arrange staggered lashing wire, the inside of warp-wise band arranges the warp-wise lashing wire, and adjacent warp-wise bar interband arranges the enhancing band.

Enhancing band described in the utility model, it is characterized in that strengthening band along warp-wise at interval in 800～1000mm scope and the both sides knitting width be to arrange in the scope of 75～100mm, the width that strengthens band is 100～200mm.

The beneficial effects of the utility model are that the colliery is big, mesh-structured reasonable, uniform and stable with spacer bar belt supporting false top net intensity, can effectively safeguard country rock between anchor pole, prevent that broken sillar from collapsing, and have good shock-resistant and anti-concentrated load performance.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation; In the accompanying drawing 1:

1. warp-wise band, 2. broadwise band, 3. the warp-wise lashing wire 4. strengthens band, 5. staggered lashing wire.

The specific embodiment

1 pair of the utility model describes in further detail by reference to the accompanying drawings, so that the public grasps implementation method of the present utility model better, the concrete scheme that the utility model is implemented is: described colliery is made up of warp-wise band 1, broadwise band 2, warp-wise lashing wire 3, enhancing band 4, staggered lashing wire 5 with spacer bar belt supporting false top net, it is characterized in that warp-wise band 1 and the 2 vertical interlaced settings of broadwise band, warp-wise band 1 arranges staggered lashing wire 5 with broadwise band 2 staggered places, the inside of warp-wise band 1 arranges

warp-wise lashing wire

3, and 1 of adjacent warp-wise band arranges and strengthens band 4.

Enhancing band 4 described in the utility model, it is characterized in that strengthening band 4 along warp-wise at interval in 800～1000mm scope and the both sides knitting width be to arrange in the scope of 75～100mm, the width that strengthens band 4 is 100～200mm.

Claims

1. the colliery is with spacer bar belt supporting false top net, formed by warp-wise band (1), broadwise band (2), warp-wise lashing wire (3), enhancing band (4), staggered lashing wire (5), it is characterized in that warp-wise band (1) and broadwise band (2) vertical interlaced setting, warp-wise band (1) arranges staggered lashing wire (5) with broadwise band (2) staggered place, the inside of warp-wise band (1) arranges warp-wise lashing wire (3), arranges between adjacent warp-wise band (1) to strengthen band (4).

2. colliery according to claim 1 is with spacer bar belt supporting false top net, it is characterized in that strengthening band (4) along warp-wise at interval in 800～1000mm scope and the both sides knitting width be to arrange in the scope of 75～100mm, the width that strengthens band (4) is 100～200mm.
