Abstract
Underground coal mine is along with the propelling of work plane, and the support in stope drift active workings also needs to remove in time.If adopt shed shoring in stope drift active workings, then support material not easily reclaims, and will be embedded in down-hole; Bar timbering is coordinated, then higher the and supporting restricted lifetime of cost according to hydraulic prop; In addition, along with coal mining depth is deepened, roof weighting can occur often, and rigid support plastic strain can occur when being subject to so large impact, and support is destroyed.It is low that its solution applies a kind of cost exactly, the plasticity air filling type rubber standoff easily reclaimed.During supporting, inflated by support, the support of inflation is heaved, and with top plate contact, both plays support action, and also available buffer acts on suddenly the pressure on support simultaneously, and support is not destroyed when pressing suddenly; When removing support, support is exitted, then by support disassembly & recycling.This supporting structure is simple, novel, unique, and using simple, convenient, is that of roadway support field innovates greatly, remarkable in economical benefits.
Description
Technical field
The present invention relates to a kind of New-support of colliery tunnel support, is a kind of air filling type mine rubber support.
Background technology
At present, underground coal mine is along with the propelling of coal-face, and the support in stope drift active workings also needs to remove in time.Adopt shed shoring in stope drift active workings, then support material not easily reclaims, and will be embedded in down-hole; Bar timbering is coordinated, then higher the and supporting restricted lifetime of cost according to hydraulic prop; In addition, along with coal mining depth is deepened, roof weighting can occur often, and rigid support plastic strain can occur when being subject to so large impact, and support is destroyed.Be badly in need of a kind of supporting easy, reclaim easily, the new type mining support acting on suddenly pressure on support can be cushioned.
Summary of the invention
It is easy that object of the present invention is just to provide a kind of supporting, reclaims easily, can cushion a kind of new type mining support acting on suddenly pressure on support.
The present invention includes steel arch, inner liner and rubber layer, rubber layer is wrapped in inner liner and is closely connected with steel arch, and inner liner is connected with rubber outer by valve inside.During supporting, inflator pump is inflated to inner liner by valve inside, rubber layer is heaved, roof supporting.Because the part being close to rock is rubber, so support can cushion roof pressure, all supports can carry roof pressure jointly, alleviate the pressure that each support carries.Puffer-type mining bracket, its feature is the sudden change of energy compensator or trimmer pressure, makes steel arch that deformation be less likely to occur.
The present invention is applied to the temporary lining in stope drift active workings.
The present invention is owing to adopting said structure, and namely by inner liner and the rubber layer supporting roof of inflation, and steel arch and top board directly do not contact; Steel arch can not directly bear the impact of pressing suddenly on the one hand, also makes support and cancel support more simple and convenient on the other hand.In addition the waste of support material in stope drift active workings can not also be caused.

Detailed description of the invention
The present invention does below in conjunction with drawings and Examples with detailed description.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the present invention includes rubber layer (1), steel arch (2) is closely connected by draw-in groove (5), have inner liner (3) in rubber layer and the interior cavity formed of steel arch, inner liner (3) is connected with rubber layer (1) by valve inside (4).
When erection bracket, valve inside (4) is exitted, support is easily set up.After the good support of supporting place frame, inflator pump is utilized to be inflated in inner liner by valve inside (4).Inner liner after inflation is by the rubber layer jack-up of outside high strength, and tunnel top contact, plays support action.By valve inside (4) venting when reclaiming support, the inner liner (3) after venting and rubber layer is flat gets off, departs from top, tunnel, recovery after then being fallen by support.The object of the invention is to improve jointly bearing pressure and improving the rate of recovery of support of support.Supporting structure of the present invention is simple, novel, unique, uses simple, convenient, is that of temporary working supporting field, colliery innovates greatly, applies and have great Social benefit and economic benefit.
