Abstract

It the utility model is related to technical field of mine support, and in particular to a kind of buffer-type high intensity mine support system.Using including top shield rack, side support pile and anchor pole, the lower end of the supporting rack is fixed in the support pile of side, the supporting rack includes upper and lower two layers of bar-mat reinforcement, padded coaming and some arch steel pipes are provided between two layers of bar-mat reinforcement, the arch steel pipe is provided with grouting port and stomata;The anchor pole passes through the mesh of the bar-mat reinforcement, and supporting rack is fastened on to the technical scheme on palisades by the fixed plate of afterbody.The utility model can both have high-strength bearing capacity, and bending rigidity is big, be not easy torsional deformation, and the addition of padded coaming, make it have certain stress buffer ability again, not only improved rigidity bearing capacity but also improved buffer capacity.

Description

A kind of buffer-type high intensity mine support system
Technical field
It the utility model is related to technical field of mine support, and in particular to a kind of buffer-type high intensity mine support system.
Background technology
In recent years, because coal resources are reduced, exploitation gradually develops into deep by superficial part.But with adding for mining depth Deep, the pressure that mine is born is increasing, and considerable damage coal petrography may not only be thrown into tunnel by huge pressure, destroys tunnel Support system and surrounding rock structure, more the life of underground work personnel is threatened.Traditional mine support system uses steel more Property structure, not to the buffer capacity of stress, easily cause support system damage, and traditional mine support system, with Its supporting intensity of the increase of depth does not reach requirement.
Utility model content
To solve the above problems, the utility model provides a kind of buffer-type high intensity mine support system.
To achieve the above object, the utility model adopts the following technical scheme that:
A kind of buffer-type high intensity mine support system, including top shield rack, side support pile and anchor pole, the branch The lower end of protecting wire net frame is fixed in the support pile of side, and the supporting rack includes upper and lower two layers of bar-mat reinforcement, between two layers of bar-mat reinforcement Padded coaming and some arch steel pipes are provided with, the arch steel pipe is provided with grouting port and stomata;The anchor pole is described in The mesh of bar-mat reinforcement, and supporting rack is fastened on palisades by the fixed plate of afterbody.
Preferably, the side support pile includes the preceding support pile positioned at mine side-walls, is fixed on side support pile Interior supporting rack, the rear support pile positioned at mine side-wall outer side and the lattice being connected between preceding support pile and rear support pile Structure steelframe, injecting paste material is poured between the preceding support pile and rear support pile.Double-row-piles Structure is employed, can so reduce and account for The underground space, there is preferable supporting effect again.Lattice steelframe between two row's support piles and the injecting paste material knot poured Close, firm pile body structure can be formed, the supporting intensity of side support pile can be greatly enhanced.
Preferably, the padded coaming is foam or rubber, the cost of material is low, and good buffer effect, can save into This, it is easy to utilize.
Preferably, it is provided with vertical anchor pole on the outside of the preceding support pile.Vertical anchor pole can make full use of deep soil layer to carry The anchor force of confession, effectively increase the safety factor for compressive stress of double-row pile, reduce the building-in depth of pile body.
Preferably, the injecting paste material is high-grade concrete, the cost of material is low, and can form high-strength structure.
Preferably, high-grade concrete is poured by grouting port in the arch steel pipe.Coagulation is added in steel pipe Soil, makes concrete have restraining force, and such structure makes the pressure of outside by steel pipe and its inner concrete shared, filling Effect makes the anti-pressure ability of support be far longer than steel pipe or the single action effect of coagulation support.
As can be seen here, the utility model both has high-strength bearing capacity, and bending rigidity is big, is not easy torsional deformation, and delays The addition of material is rushed, makes it have certain stress buffer ability again, rigidity bearing capacity had not only been improved but also had improved buffer capacity. There is substantive distinguishing features and progress compared with prior art, its beneficial effect implemented is also obvious.

Embodiment
As shown in figure 1, a kind of buffer-type high intensity mine support system, including top shield rack 1, side support pile 2 With anchor pole 12, the lower end of the supporting rack 1 is fixed in side support pile 2, and the supporting rack 1 includes upper and lower two layers of reinforcing bar Net 4, padded coaming 5 and some arch steel pipes 3 is provided between two layers of bar-mat reinforcement 4, the arch steel pipe 3 is provided with grouting port 7 With stomata 8;The anchor pole passes through the mesh of the bar-mat reinforcement 4, and supporting rack 1 is fastened on into rock by the fixed plate 6 of afterbody On wall.
Preferably, the side support pile 2 includes the preceding support pile 9 positioned at mine side-walls, is fixed on side supporting Supporting rack 1 in stake 2, the rear support pile 10 positioned at mine side-wall outer side and it is connected to preceding support pile 9 and rear support pile 10 Between lattice steelframe 11, poured injecting paste material between the preceding support pile 9 and rear support pile 10.
Preferably, the padded coaming 5 is foam or rubber.
Preferably, the outside of preceding support pile 9 is provided with vertical anchor pole 12.
Preferably, the injecting paste material is high-grade concrete.
Preferably, high-grade concrete has been poured by grouting port 7 in the arch steel pipe 3, will note after the completion of pouring Slurry mouth 7 is closed.
