Description
Technical field
The present invention relates to mining technique field, more particularly to intensive fault zone working face under complex geological condition
Face method for designing.
Background technology
Usually because ocurrence of coal seam is uncertain, geological structure is complicated in tomography intensive exploiting field, and craven fault is relatively more,
The unfavorable geological conditions such as coal seam thickness is unstable, causes to exploit difficulty increase, it is impossible to arrange high-yield and high-efficiency work
Make face, economic benefit is poor.Cause exploiting field entirety roadway engineering amount many, ten thousand tons of exploiting field drivage ratio height, work
Face is frequently moved passing fault, and coal resources loss is serious.In particular cases, because fault throw affects to cause phase
Adjacent work surface different coal layer position is close to and is even docking together, if continuing according to tradition exploitation same coal seam
Method, passing fault continually look for same layer coal, cause the increase of roadway construction total rock quantities and Coal Loss,
Cause whole exploiting field realize that economical and efficient is exploited.
Need to provide a kind of intensive tomography area working face method for designing, further find out tomography distribution, realize disconnected
The safe and efficient production in layer compact district.
The content of the invention
The invention provides a kind of efficient fully-mechanized mining working method for designing in the intensive fault zone in colliery, introduces dimensionally
Seismic exploration technology, finds out exploiting field tomography distribution situation, optimizes coal-mining method, reduces geologic risk to greatest extent,
And realize that special Adjacent Working Face different coal merges exploitation, create good economic benefit.
The efficient fully-mechanized mining working method for designing in the intensive fault zone of the present invention, concrete grammar is：
(1) Mining block design is coal seam group combined layout, and a point Multi sectional arrangement moves towards coal wall or inclined longwall
Work surface, retreats.
(2) optimizing design scheme of 3-d seismic exploration technology for exploiting field Exploitation Status, is introduced, can be found out and be adopted
The tomography of drop 3-10m in area, energy Optimization Work face recovery scheme, arranges stope along tomography.
(3) it is larger for special Adjacent Working Face fault throw, and when nearer with unitized production coal seam spacing,
Make same gate road also cross upper and lower two coal seams, work is arranged by reasonable selection heading layer position
Face and adjustment mining sequence, realize the merging exploitation of different coal work surface.
The invention has the beneficial effects as follows:In the intensive exploiting field of tomography, realize that work surface connection and reasonable arrangement evades tomography, create
Highly efficient and productive work surface is found.Additionally, design interrupting layer in innovation conventional operation face continues along same when larger
The idea of coal seam driving, by using fault throw, two coal seams of rational exploitation, considerably reduces tomography
The cost of winning of compact district.

The passing fault total rock quantities that one coal seam is brought.
Embodiment 1：According to Fig. 1：The optimizing design scheme of former two layers of coal, four sections of the program point,
Back production is carried out using strike long wall method.
Embodiment 2：According to Fig. 2：The optimizing design scheme after 3-d seismic exploration is introduced, exploiting field is adjusted
Arrangement based on being in tilted layout is divided into 3 main exploitation block sections, compares original and move towards longwell arrangement, reduce complete
Rock gangway road 1300m, whole enzymatic method 337m, reduce removal of home and remove 6 times, 200,000 tons of multi-party coal output, it is contemplated that
13,000,000 yuan of input can be saved.
Embodiment 3：According to Fig. 3：It is big for special Adjacent Working Face fault throw and be close between unitized production coal seam
Away from when, using same gate road exploitation different coal design instance graph；WF7 in Fig. 3 between work surface 1,2
Tomography fault throw about 19m, close to interlamellar spacing 24m of two, four layers of coal, in work surface design process, lane
Road is first tunneled wait disclosing after WF7 tomographies, along two layers of coal driving of work surface 2 along four layers of coal of work surface 1,
Realize that Adjacent Working Face two-layer coal merges exploitation, realize the exploitation of work surface economical and efficient.
