Description
Technical field
The present invention relates to a kind of seam mining method, " adopt-fill-stay " coupling controlled particularly to a kind of colliery strata movement
Close harmonic extraction method.
Technical background
Exploitation certainly will cause ground settlement and deformation.In phreatic table district higher, mining type back production coal money routinely
Source, meeting is a large amount of hydrops in the subsidence basin that earth's surface is formed, if building or structures are positioned at subsidence basin, can cause building
Thing or the long-term hydrops of structures or excessive moisture, impact is normal to be used；Building or structure also can be caused when earth's surface deformation is bigger
Build the damage of thing.Therefore, when earth's surface, buildings or structures are more, when pressure coal amount is big, the most typically take earth's surface buildings or structures different
Ground resettlement, or take underground filling exploitation and Striping noise measure, to avoid or to reduce the mining damage of earth's surface buildings or structures
Influence degree.Different measure has a characteristic that
1, strange land resettlement
Buildings or structures from mines influencing area, resettlement is to the place of not affected by exploitation.The method can fundamentally solve
Certainly buildings or structures are affected by exploiting, and are the maximally efficient approach avoiding Mining subsidence.But the method existence expropriation of land difficulty,
Fund input is relatively big, resettlement cycle length, relationship between industry and agriculture are difficult to the problems such as coordination.
2, conventional exploitation
Refer to comprehensive mechanical coal mining, the coal-mining method of whole caving methods management top board.This method resource recovery is the highest, high yield
Efficiently, system is arranged simple, and tunnelling amount is little, but the infringement to surface buildings, structures is the most serious.
3, Striping noise
Working seam being divided into beam shapes, stays ratio by necessarily adopting, adopt one, stay one, intervening sequences is exploited, and makes to stay
Under strip coal pillar support overlying rock, thus reach reduce surface movement and deformation method.The method preferably can control ground
The movement of table and deformation, buildings or structures are less by mining influence, but lose that coal is serious, resource recovery is low, and the rate of extraction is only
About 40%, when adopting the biggest, the rate of extraction is lower.If coal column stay set width bigger time to lose coal serious, time too small, coal column can be caused
Unstability, does not has the effect that control overlying mining rock moves.
4, filling mining (entirely adopt and entirely fill)
After filling mining refers to mining face under mine exploitation, spoil, garbage or mastic, high-water material etc. is used to be filled to adopt
Dead zone, crushes with suppression, thus plays the recovery method controlling rockmass and surface subsidence deformation.The method can effectively control
Surface subsidence and deformation, resource recovery is high；Exploit with filling alternately operating, influence each other so that yield poorly.Fund is disposable
Putting into big, cost of ton coal increases, and the unwarranted mining area of filler is difficult to carry out the method.
Actual measurement and experimental study show, ground and strata movements is controlled primarily by key stratum, when Chief layer is complete,
Above it, rock stratum is mobile with the movement of key stratum, and sinking and the deformation on earth's surface are the least；The disrumpent feelings meeting of Chief layer causes
Quickly sinking under earth's surface, surface subsidence speed is periodically the most disrumpent feelings and present the change of cycle jumping characteristic with main key stratum, works as key stratum
Movement and deformation when reaching earth's surface unconsolidated formation, unconsolidated formation can adjust the non-homogeneous sinking absorbing key stratum, if unconsolidated formation is relatively thin,
Being not enough to all absorb heterogeneous deformation, earth's surface can occur moderate finite deformation, and when unconsolidated formation is sufficiently thick, and key stratum is disrumpent feelings to be caused
Discontinuous Deformation will all be absorbed, and earth's surface shows as continuous modification.Mineral Engineering research in recent decades achieves prominent
Achievement, particularly critical sheaf theoretic proposition, solve on-the-spot many technical problems, and carry for design of its support, gas drainage technique
Supply theoretical foundation.In overlying strata, key stratum can control the movement of overlying strata above it, and main key stratum is the most disrumpent feelings and steady in a long-term
In the case of, earth's surface occur movement and deformation less, this be design exploitation " three times (build/structures under, under railway and under water body) "
The basic principle of coal resources.
Any of the above recovery method intrinsically, is effective protection on high efficiente callback or the earth's surface laying particular emphasis on resource,
Can not the two take into account.China's " three times " pressure coal problem generally exists at present, and some mining areas pressure coal amount is even up to 100%, resettlement
Expense enterprise is difficult to bear, and the response rate of Striping noise resource is the lowest, and whole filling mining costs are the highest.Therefore, in " three times "
In the urgent need to a kind of safety, high-recovery, the production technique of low cost in exploitation.
In sum, Migration is difficult to carry out, easy hydrops, pressure big, widely distributed the building of coal amount after subsidence
(structure) is built and is exploited under thing；One will be sought and can reduce sinking and earth's surface deformation, to reach to protect earth's surface buildings or structures
Safe handling, ensure resource recovery requirement, exploitation measure that again can be cost-effective.
Summary of the invention
The technical problem to be solved is to provide a kind of movement that can efficiently control rock stratum and earth's surface and change
Shape, Mining subsidence can be reduced, reduce area pack completeness, and improve that the colliery strata movement of coal recovery rate controls " adopt-
Fill-stay " coupling harmonic extraction method.
The present invention is achieved through the following technical solutions: the control of colliery strata movement " adopt-fill-stay " coupling harmonic extraction side
Method, is divided into m production unit by mine district, and m is positive integer；The exploitation of production unit is divided into unilateral filling and bilateral filling
Both of which, each production unit carries out reserved coal pillar, part filling and the cooperative type filling mining of partial mining, sets to stay
Coal column is core, makes coal column, obturator and is caving body coordination support top covering rockmass, controlling the movement and deformation value of rock stratum and earth's surface.
The strata movement control of above-mentioned colliery " adopt-fill-stay " coupling harmonic extraction method, according to unilateral filling model, often
Individual production unit all uses unilateral fill pattern to exploit: unilateral filling model is in reserved coal pillar side, is sequentially arranged one
Individual filling operation face and a not filling operation face；First fill in the cut and fill cellular zone of n-th production unit
Fill out working face extraction and filling forms obturator；Then the whole caving method production unit districts in n-th production unit are carried out not
The back production of filling operation face, forms goaf, and n is positive integer and n less than or equal to m；The coal column of adjacent two production unit with adopt
Dead zone is adjacent.
The strata movement control of above-mentioned colliery " adopt-fill-stay " coupling harmonic extraction method, according to bilateral filling model, often
Individual production unit uses bilateral fill pattern to exploit, and bilateral filling model is to lay one successively in the side of reserved coal pillar
Filling operation face and a not filling operation face, and lay another filling operation face at the opposite side staying the coal column set；First
In the cut and fill cellular zone of n-th production unit, carry out the back production of filling operation face and filling forms obturator；Then exist
Whole caving method production unit districts of n-th production unit carry out the back production of not filling operation face, form goaf, and n is the most whole
Number and n are less than or equal to m；Adjacent two production unit use obturator adjacent with goaf.
The strata movement control of above-mentioned colliery " adopt-fill-stay " coupling harmonic extraction method, in whole mine district, one
The coal column of point production unit only has obturator, the both sides of the coal column of another part production unit all to have obturator in side；Adjacent
Two production unit use obturator adjacent with goaf or use coal column adjacent with goaf.
The strata movement control of above-mentioned colliery " adopt-fill-stay " coupling harmonic extraction method, filling operation face and not stower
Make face to merge, back production simultaneously.
It needs to be noted: the width of reserved coal pillar can be determined by basicly stable requirement, filling operation face, not filling
Face width, can be determined by sub-extraction or the most insufficient requirement according to concrete geological mining condition；This is to this area skill
It is common knowledge for art personnel, needn't elaborate any further at this.
This invention provides the benefit that: the control of colliery of the present invention strata movement " adopt-fill-stay " coupling harmonic extraction side
Method is particularly well-suited under buildings or structures and water body, low-angle dip or nearly level and directly top are more complete, overlying strata lithology in being hard or
The seam mining of competent bed.Seam mining takes " fender+two (singly) filling face, side+two (singly) side extreme astatic
Face ".Control overlying mining rock is caving scope, thus reduces movement and deformation of overburden strata degree, reaches the most controllably table movement and deformation, can carry again
The purpose of high resource recovery.
Colliery of the present invention strata movement control " adopt-fill-stay " coupling harmonic extraction method, by reducing reserved coal pillar width
Degree improves resource recovery, utilizes obturator filling to adopt space to reduce, and makes key stratum displacement and deformation in overlying rock send out
The space of exhibition reduces, and jointly supports the pressure of overlying key stratum with fender, plays auxiliary supporting role, and to coal (rock) body and
Roof and floor country rock provides certain resistance, and (it is to cause to cover that stress is concentrated to slow down the stress concentration phenomenon in coal column and key stratum
Rock deformation and destruction cause the basic reason that ground is damaged) so that obturator and Pillar load support propping up of key stratum jointly
Support body system, plays the effect reducing surface movement and deformation；On the other hand obturator produces lateral pressure to fender, makes fender
It is in two-way or three-dimensional stress state, improves the country rock situation of fender, improve the ability of its resistance to deformation so that it is have relatively
Good integrity and stability.
The Striping noise generally used, coal column both sides are goaf, and coal column is in pure stress or two-dimensional state of stress, adopts
At dead zone, top board is by the bigger movement and deformation of scope.Apply that colliery of the present invention strata movement controls " adopt-fill-stay " coupling association
Tune to open mining method to reduce strip coal pillar and stay and set width, and can the deformation range of effective controlroof, it is ensured that main in overlying strata
Key stratum is the most disrumpent feelings and steady in a long-term, can reach to reduce the extension from the bottom to top of top board movement and deformation, make earth's surface not by or be subject to
To less mining effect.
The present invention is compared with Striping noise, and the stress state improving coal column is filled in coal column side, improves recovery ratio.With entirely adopt
Entirely fill and compare, decrease charging quantity, but enhance the support strength of obturator and coal column, improve CONTROL OF STRATA MOVEMENT effect, save
