Description
Technical field
The present invention relates to a kind of steel tendon, it is particularly suitable for new used in the roof timbering engineering in coal mine sinking and drifting
Type is mining steel tendon
Background technique
Tunnel is the necessary channel of underground mine exploitation, and unimpeded, stable tunnel is the guarantor of safety of coal mines, high-efficiency mining
Barrier.According to incompletely statistics, the tunnel overall length that China's state-owned coal mines newly tunnel every year reaches 12000km, State owned coal mine alley way anchor
90% or more bar supporting accounting, the anchor pole quantity consumed every year reach more than one hundred million.
In existing suspension roof support system, anchor pole huge number has inverted wedge type anchor rod, pipe-seam type anchor rod, tube-expanding type anchor
Bar, resin anchor, Extendable anchor rod etc..Most generally use now or resin anchor, cardinal principle is twisted steel anchor rod
Bond-anchorage is carried out, it can be achieved that end, lengthening or full length fastening by resin explosive roll or pump note resin.But the anchor pole belongs to
Rigid material is limited by the limitation of head-room and constructing operation, and rock-bolt length is generally within the scope of 2.0m~2.6m；Meanwhile
Rock-bolt length is too long, and will increase the cost and weight of anchor pole.
Current coal in China exploitation is gradual to turn to deep, and mining conditions are extremely complex, meanwhile, Mechanization Level is again substantially
It improves, the drift section needed is increasing, and therefore, back anchoring thickness should also increase, and the rock-bolt length needed ought to
It lengthens, the tunnel of general buried depth 400m~800m, rock-bolt length should be 3.5m~4.0m, and head-room limits anchor pole mistake
It is long, so, urgent need develops one kind and had not only been able to satisfy length requirement but also the mining supports material of energy uniform force.
Summary of the invention
Technical problem: shortcoming in view of the above technology provides a kind of length and meets the requirements, and steel tendon main body stress is equal
