Description
Technical field
The present invention relates to a kind of rock mass engineering project underground pressure management method, the ground pressure pipe of country rock is exploited more particularly, to underground mine
Reason and control method, can be widely applied to the rock mass underground engineerings such as mine, tunnel cave, subway, are particularly suitable for use in underground mine deep
The underground pressure management of exploitation and control.
Background technology
Mine down-hole rock mass subject the effect of the weight and other power of overlying rock before not excavating and is in flat
Weighing apparatus state, referred to as primitive stress poised state.Once there is excavation project after ore-rock body is excavated or near it, its primitive stress
Poised state is just destroyed, and the stress in ore-rock body will be redistributed to reach new balance, in the process, secondary to answer
The field of force can form region of stress concentration and stress relaxed area during quadratic distribution in the certain area excavated around scope
Domain, will make the rock mass around tunnel or stope be moved, deformation and failure, have influence on the stability of the underground engineerings such as stope,
This phenomenon, which referred to as is pressed, to be shown.Press that to show be the major safety problems faced in the underground mining of mineral deposit thisly.Therefore,
Disclose Ground pressure activity rule, press to management and control that to show be the basis for realizing Mine Safety in Production.
The presence of ground pressure, makes mining activity become difficult, must in order to ensure being smoothed out for safety in production and actual mining
Press harm measure with being reduced or avoided must be taken, or positive pressed using ground is exploited, this work is exactly underground pressure management.

In " deep rock mass mechanics study is with exploring " text of table, domestic and international deep coalmine, deep metallic ore, profound underground work are described
The deep rock mass mechanics engineering development situation of journey, proposes and analyzes some key issues that deep rock mass mechanics needs to solve.
Although document above and existing other achievements propose some analysis the law of ground pressure, press and Depressurized mining to control
Certain methods, but these underground pressure management patterns substantially lack systematicness and dynamic, and rock mass in rock mass engineering project is not fully demonstrated and is consolidated
The complexity of stress field dynamic change in some particularity and digging process.
The content of the invention
The purpose of the present invention is aiming at the above-mentioned problems in the prior art, and back production effect can be improved by providing one kind
Back production safety, the underground rock engineering underground pressure management and control method of reduction cost of winning, can be ensured.
To realize the above-mentioned purpose of the present invention, a kind of underground rock engineering underground pressure management of the invention and the method for control, adopt
Realized with following technical scheme and step：
1) research discloses regularity of ground pressure occurrence (Study)
By investigating geologic information, the test stress of primary rock, test ore-rock mechanics parameter, reduction mechanics parameter, structure mechanics
Model, on the basis of mining planning, mining methods and production practice is descended in combination, using numerical simulation, analog simulation,
Theory analysis, field monitoring, the method for engineering analogy, the analysis each step of Underground rock mass excavate the ground to be formed during goaf
Press Strata Behavior, obtain in Underground rock mass stress rise area, stress relaxed area, Tension Stress Zone, Rock Displacement Movement angle, be press
Management provides theoretical foundation；Described ground pressure show including：Tunnel is collapsed, roof collapse, strata movement, surface subsidence etc..
2) guiding exploiting field transfer (Transter) is pressed
According to the regularity of ground pressure occurrence that 1) step is disclosed, with reference to production practice, horizontal resection is used in Underground rock mass
Lane, the mode of perpendicular cuts groove guide the stress in exploiting field to be shifted, redistribution forms new stress rise area, it is new should
Power reduces area, while stope drift active workings are arranged in new stress relaxed area, so as to improve the stress distribution shape of ore-rock body in exploiting field
State, reduces the edge stress such as roadway, chamber engineering, is ore body high-efficiency mining reconstruction environment.
1. when mining area is using vertical stress to be main, by perpendicular cuts, exploiting field (stope, tunnel or chamber etc.) top is covered
The exploitation engineering that terrane stress is wholly or partially transferred in surrounding, exploiting field section under pressure arch is solely subjected to the weight of overlying ore-rock,
Now vertical stress value significantly reduces and becomes prone to exploitation.
2. when mining area is using horizontal stress to be main, by horizontal resection, mining area (stope, tunnel or chamber be will act on
Deng) horizontal stress of interior ore body cut-off, horizontal stress reduction area is formed, now horizontal stress value is significantly reduced and become in exploiting field
It is easy to excavate.
3) exploiting field high stress avalanche (Use) is utilized
Above the 2) step the redistribution of rock mass regional stress state can be realized by stress transfer, form new stress reduction
Area and new stress rise area, the 2) on the basis of, fully with reference to different production practices, utilize stress rise area's stress concentration
It is deep in being arranged in the high stress characteristic that feature or deep-well itself are present, the stress rise area new by being formed on goaf top plate
Hole, goaf top plate rock falling is induced using induction caving mode, eliminates the impact disaster that goaf top plate upper stress is concentrated
Hidden danger, while forming the coating needed for back production.
In 3) step, underground high stress disaster is changed into controllably pressure energy and carries out broken rock, turning for high stress disaster is realized
Utilization is changed, back production efficiency is significantly improved, cost of winning is reduced.
4) press to control operation area and show (Control)
The 1), 2), 3) on the basis of step, on still because ground pressure show influence tunnel, chamber, exploiting field safety section, adopt
Supporting is carried out to stope drift active workings with the mode of anchor pole or the internal reinforcement of anchor cable, to press and show with further controlling, ensured time
Adopt safety.
In 4) step, using anchor pole, anchor cable or slip casting stope drift active workings can also be carried out with the internal reinforcement mode of supporting, and
Outside supporting, joint reinforcement supporting, the mode of waste fill or mine tailing consolidated fill are pressed and shown with controlling, to ensure that back production is pacified
Entirely.Described outside supporting use one or both of grillage, steelframe, hydraulic support, artificial feigned column, gunite concrete and with
On combination, described joint reinforcement supporting is using anchor net, the composite reinforcement mode of net spray.
Compared with prior art, a kind of underground rock engineering underground pressure management of the invention has the following advantages that with control method：
1. the characteristics of rock mass is intrinsic in rock mass engineering project is directed to, by the way that " research the law of ground pressure (Study)-guiding ground pressure is shifted
(Transter)-using ground pressure avalanche (Use)-control ground pressure shows (Control) " circular management mode, realize ground
The systematicness and dynamic of pressure pipe reason.
2. underground pressure management STUC circulations are comprehensive circulations, and four-stage is relative, is interrelated and fusion, should
Pattern more meets the characteristic that rock mass engineering project is repeatedly excavated, disturbed repeatedly.
3. STUC circulations breach the conventional underground pressure management thinking based on Earth pres-sure control, to adjust stress state, synthesis
It is core concept using ground pressure, realizes the great theoretical breakthrough of underground pressure management pattern.
4. underground pressure management and mining area construction, engineering geology, mining methods, mining technology etc. have been subjected to dynamic bind, it is real
Now exploit safer, more economical, more efficient.
