Product Introduction Of Tunnel Meshy Frame Yieldable Support
Tunnel meshy frame yieldable support reduces repair recovery of tunnelling and remove the biggest danger of tunnelling posterior shut up. It's speed up tunnelling into the lane relatively. At same time it reduces recovery of two ways coal mining, the cost greatly and provide reliable guarantee for mining engineering safety production.
1. Strong crushing resistance and good into a lane.
Tunnel meshy frame yieldable support fastenings use canvas to make supporting structure is rigorous and stress dispersion.The reason is that stress distribution of shape of arch arc and natural arched roadway stress similar, stress is relatively uniform anti-pressure ability is stronger than wooden shacks and i-steel trapezoid graphic support.Because tunnel meshy frame yieldable support is in shape,durable compression,not like wooden fold beam leg or I-steel shed beam bending.It extends the supporting time reduces tunnel recovery repair and increases service life.
2.High safety factor and strong anti-disaster ability.
U tunnel meshy frame yieldable support has rigorous supporting structure use two canvas fastening on each side.Beam legs combine closely wholistic unite force is strong,legs are not easy to knock off.Although there is water to pull dangling support is not easy to sinking sharply relys on tunnel self compression of dispersion.
3.Safe and smooth, walking is convenient.
The protect pressure is high when use anti-U tunnel meshy frame yieldable support. We can adapt undercutting method sill restore the original section when mining height is not enough.And framework is not easy to change support strength is almost unchanged.
4.Reduce the high roof caving,easy to outfire.
The fewer support double pick back use U tunnel meshy frame yieldable support and roof laying metal mesh the possibility of the roof fall is less.As long as simultaneous drifting control plate well or reduce the roof caving ultra-high,it can reduce gas accumulation and fire smoke relatively.
5.The stent deformation, Easy to maintain quality standardization.
Tunnel meshy frame yieldable support compressive strength is high,protection performance is good,deformation degree is small,keep the original state even when mining drivage construction basically.Photos Of Tunnel Meshy Frame Yieldable Support
