Description
Technical field
The present invention relates to field of mining, more particularly to a kind of old goaf grouting filling control earth's surface residual settlement method.
Background technology
As economic and society continuous development, urban construction scale are gradually increased, increasing proposed building is (such as
House, Factory Building etc.) positioned at the old above goaf in colliery.Due to the disrumpent feelings rock mass in old goaf and its top, to yet suffer from part residual
Remaining space, As time goes on and under proposed building load (such as gravity) effect, in old goaf, rock stratum may be again
Compacting, causes rock stratum and earth's surface residual settlement occur, brings larger security risk to top building.Therefore, to old mined out
It is the important measures for ensureing New Buildings safety in such region to carry out administering, controlling earth's surface residual settlement.In prior art
The method for disclosing many coal-face support rear goaf fillings, these technologies are required to safeguard large volume of connection
Filling can be implemented in mined out space, but the almost all sillar that is broken is full of in old goaf, it is difficult to form large-area company
Logical packing job space.
The content of the invention
The technical problem to be solved is to provide a kind of old goaf grouting filling control earth's surface residual settlement side
Method, with above-mentioned multinomial defect caused by solving in prior art.
For achieving the above object, the present invention provides following technical scheme：A kind of old goaf grouting filling control earth's surface
Residual settlement method, comprises the following steps：
1) old goaf basic parameter and information are collected, including limit of mining, mining height M, mined out section length, goaf width
Degree, can grouting filling height, adopt depth, surface subsidence amount S, caving zone height h；
2) calculate in old goaf can grouting filling spatial altitude, its value for mining height M deduct successively surface subsidence amount S,
Difference obtained by remaining broken bulk (0.03～0.05) h of the goaf limit；
3) construction ground drilling, several group of vertical drilling of constructing from the earth's surface of old above goaf to goaf, drilling
It is 50～100m along the spacing of old goaf length direction, drilling number is mined out section length divided by the spacing of wells；
4) flushing liquor total loss in hole is such as run in drilling process, is then stopped drilling, and is implemented grouting filling this layer of position,
After grouting pressure to be formed, stop grouting filling, be changed to continue downwards drilling, so circulate, until seat earth is got into, and in fact
Last wheel grouting filling is applied, so as to complete old goaf filling；
5) implement after grouting filling terminates after all drilled hole, the construction ground drilling in the range of the old dead zone, using core drill
Enter, detect mortar thickness, if mortar thickness reaches the spatial altitude noted of calculating, show that grouting filling quality meets and require, it is no
Then, construction inlet well should be continued around inspection hole, carries out supplementing grouting filling.
Preferably, the step 1) in, using mined out sector width, mined out section length, can grouting filling height three take advantage of
Product determines grouting filling total amount.
Preferably, the step 3) in, the whole hole of drilling is constructed to goaf.
Preferably, the step 4) in, grouting pressure should be less than the deadweight of above goaf overlying strata.
Preferably, the radius for checking construction inlet well around drilling is 10-20m.
Preferably, the drilling drilling is that side bores marginal not, sees that mode is noted in leakage with grouting filling.
Using the beneficial effect of above technical scheme it is：The present invention and the direct placement method phase in coal-face support rear
Than the present invention implements grouting filling using surface drilling, remaining crack that can effectively in sensible old goaf, need not big face
Long-pending connection packing job space, even if in the case of old goaf internal crack degree of communication is less, also can be bored by encrypting
Hole reaches effective filling in crack, thus can have the residual settlement of earth's surface in control control construction zone.
Description of the drawings
Fig. 1 is the schematic diagram of bored grouting filling of the present invention.
Wherein, 1-- drillings, 2-- goafs, 3-- grouting fillings.
Specific embodiment
Describe the preferred embodiment of the present invention below in conjunction with the accompanying drawings in detail.
Fig. 1 shows the specific embodiment of the present invention：A kind of old goaf grouting filling control earth's surface residual settlement method,
Comprise the following steps：
1) old goaf basic parameter and information are collected, including limit of mining, mining height M, 2 length of goaf, goaf 2 is wide
Degree, can grouting filling height, adopt depth, surface subsidence amount S, caving zone height h；
2) calculate in old goaf can grouting filling spatial altitude, its value for mining height M deduct successively surface subsidence amount S,
Difference obtained by remaining broken bulk (0.03～0.05) h of the goaf limit；
3) construction ground drilling, several group of vertical drilling 1 of constructing from the earth's surface of old above goaf to goaf, drilling
1 along old goaf length direction spacing be 50～100m, drilling 1 number be mined out section length divided by the spacing of wells；
4) flushing liquor total loss in hole is such as run in drilling process, is then stopped drilling, and is implemented grouting filling this layer of position
3, after grouting pressure to be formed, stop grouting filling 3, be changed to continue downwards drilling, so circulate, until seat earth is got into,
And implement last wheel grouting filling, so as to complete old goaf filling；
5) implement after grouting filling terminates after all drilled hole, the construction ground drilling in the range of the old dead zone, using core drill
Enter, detect mortar thickness, if mortar thickness reaches the spatial altitude noted of calculating, show that grouting filling quality meets and require, it is no
Then, construction inlet well should be continued around inspection hole, carries out supplementing grouting filling.
Step 1) in, using mined out sector width, mined out section length, can the product of grouting filling height three determine that slip casting is filled
Fill out total amount；Step 3) in, the whole hole of drilling is constructed to goaf；Step 4) in, grouting pressure should be less than above goaf overlying strata
Deadweight.
Around inspection drilling, the radius of construction inlet well is 10-20m；Drilling drilling with grouting filling be side bore marginal not,
See that mode is noted in leakage.
Compared with the direct placement method in coal-face support rear, the present invention implements slip casting using surface drilling to the present invention
Filling, remaining crack that can effectively in sensible old goaf connect packing job space without the need for large-area, even if old
In the case of goaf internal crack degree of communication is less, can also pass through to encrypt drilling and reach effective filling in crack, thus can be with
There is the residual settlement of earth's surface in control control new building object area.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, some deformations and improvement can also be made, these belong to the present invention
Protection domain.
