Description
Technical field
The invention belongs to work shaft technical fields, specifically, the present invention relates to be adapted to deep formation and high stress
The vertical shaft composite supporting construction in region.
Background technique
The depth majority of Mineral Resources in China exploitation for a long time is in the limit of mining within 1000m, and then forms
Mature the 4th is shallow stratum complete set technology, for less more than 1000m deep mining technical research, with lacking mining depth
The technological reserve of resource.In recent years, with the continuous reduction of superficial part resource, mine gradually opening to 1000m to 1200m
It adopts depth to stride forward, a small number of metalliferous mines is building the deep-well Development system more than 1400m.With resource and energy demand
Continue to lift up and the development of economic technology, vertical shaft for mine is towards deeper more extensive development.Currently built is most deep
Maximum work shaft has: thinks mountain ridge iron ore auxiliary shaft (diameter 10m, depth 1438m), Huize Lead-zinc Mine 3# vertical shaft (diameter 6.5m,
Depth 1526m).Meanwhile the depth that China has a batch that will build is in the reserve metal air mine of 1500m or so, most deep Shandong
The vertical shafts buried depth such as the western ridge gold mine of Gold Group and Yunnan Huize Pb-Zn deep engineering will be more than 1800m.
Traditional shaft support is only with a plain concrete supporting.After traditional scheme explosion is complete, it is real that working face is built immediately following pick
Concrete lining supporting is applied, concrete walling and shaft bottom driving face distance are close, do not consider pressure from surrounding rock release distance.Needle
To the heavily stressed feature of deep shaft country rock, traditional shaft support has the disadvantage in that only with a plain concrete supporting
(1) build engineering method in the mature pick that shallow stratum construction shaft is formed for a long time, i.e., it is quick-fried characterized by short driving and short lining
Concrete walling supporting is carried out after broken, muck removal, reserved pressure from surrounding rock release time are short at once after the completion of lining cutting, it is difficult to adapt to
The Surrounding Rock Control of deep formation feature.
(2) in the High stress zone of deep, Stress relieving of surrounding rocks is necessarily required to centainly deform adjustment process.Concrete lining
It is a kind of relative stiffness supporting construction, suitable for surrounding rock deformability is poor.Obviously, it is difficult to only with common plain concrete supporting
Adapt to the requirement of deep shaft Surrounding Rock Control.
(3) traditional Construction of Silo construct one work shaft prospecting hole before going into operation, and be can satisfy conventional vertical shaft and is designed institute
The basic data needed.Technique, practical Construction of Silo position and work are built by the accuracy of engineering prospecting data, construction disturbance, pick
Bear hole location deviation etc. influence, how the information relative difficulty of accurate real-time judge shaft face lower part country rock.
(4) rock burst easily occurs for deep-well high stress, becomes one of the principal risk for influencing construction safety and prevention and treatment difficult point.Tradition
Vertical shaft plain concrete supporting, energy-absorbing function is weak when rock burst occurs, and compatible deformation is poor, vulnerable to rock burst destroying infection.
A kind of existing approximate invention " supporting structure system (CN203879506U) of rocky stratum big cross section deep shaft " phase
Than what is involved is the shaft supports for being suitable for municipal administration, highway and railway engineering field for the invention, are specifically directed to superficial part
The supporting structure system of Quaternary Strata；The invention is not also related to considering that the mines such as country rock high stress, rock burst deep shaft engineering is special
Property require.Existing approximate invention " a kind of underground shaft supporting construction (CN204646240U) in loose media " is compared, the invention
It is also the supporting structure system for the loose media of superficial part Quaternary Strata, is to loose rock mass or to cave in slag body distinguishingly
The supporting construction of layer.
In conclusion traditional vertical shaft plain concrete once supporting does not adapt to deep-well stratum characteristic, need to seek therewith
The new supporting structure system matched.

Problem during the shaft support in power region.
It according to one embodiment of present invention, may include at least one layer of flexible support.Inventors have found that primary when implementing
After flexible support, if surrouding rock stress persistently adjust deformation it is excessive, need to select a good opportunity and implement multiple flexible support.Specifically, implementing
It can be with when flexible support are as follows: implement a flexible supporting structure first, such as anchor pole+metal mesh；Then, become according to vertical shaft country rock
Shape and the disturbance situation such as rock burst occurs, whether decision implements secondary or flexible supporting structure three times, as anchor pole+steel band, anchor cable+
Steel band, anchor note.It is to be noted that anchor pole used in first time flexible supporting structure, it can be according to borehole wall deformation extent, area
Domain surrouding rock stress level, rock burst causing danger property degree etc. decide whether using surrender anchor pole.It should be noted that flexible branch
The specific number of plies of shield is not particularly restricted, and those skilled in the art can select according to actual needs.
Still another embodiment in accordance with the present invention, flexible support can for selected from gunite concrete, anchor pole, anchor net, anchor cable,
At least one of metal mesh, nonmetallic net, cable wire net and steel band.For example, can be bolting with wire mesh structure, or anchor
The flexible active combined retaining structure of the combinations such as lattice girder and shotcrete support structure or anchor net+anchor cable, anchor net+steel band.It is suitable for as a result,
Surrouding rock stress granting deformation, while can actively improve country rock performance, give full play to the self-supporting performance of country rock.It should be noted that
When carrying out multiple flexible support, each flexible support can be different flexible support types, and those skilled in the art can root
It is selected according to actual needs, as long as suitable for surrounding rock stress release, meeting surrouding rock deformation.It should be noted that flexible branch
The concrete type of shield is not limited to the above-mentioned type, and those skilled in the art can select according to actual needs.
According to one embodiment of present invention, anchor pole can be in common bolt, novel surrender anchor pole, pipe seam anchor bar
At least one of.Specifically, novel surrender anchor pole is introduced into deep shaft supporting, it is applied to high perpendicular of rock burst occurrence risk
In well engineering, the harm of rock burst bring, cost saving can reduce.Inventors have found that novel surrender anchor pole and common anchor
Bar is compared, the advantage with apparent suitable for surrounding rock Stress relief and deformation, can continue to provide restricting resistance force.
The vertical shaft composite supporting construction according to an embodiment of the present invention for being adapted to mine deep stratum and high stress areas, just
Property supporting be passive protecting, be capable of providing relative stiffness constraint, limit country rock and continue to deform.Meanwhile rigid protection constructs
Wellbore space provides shaft equipment mounting condition.Flexible support belongs to active support, has certain plastic deformation feature,
It can satisfy the release of surrouding rock deformation stress, actively improve country rock feature, give full play to country rock self-supporting characteristic.Rigid protection with
The composite supporting construction of flexible support digs block conventional process flow different from superficial part vertical shaft and only implements a plain concrete supporting
