Description
Technical field
The present invention relates to a kind of coal working face coal-mining methods, and in particular to a kind of big coal column driving adopting without coal pillar mining
Coal method belongs to mining engineering technical field.
Background technique
Exploiting field is mainly divided into several sections based on mostly retreating with longwell by coal in China production at this stage,
It is the production of production cellular organization with section working face, generally first tunnels section inner working face tunnel and open-off cut, working face equipment
After being installed in place, drawing back, while next section subsequent duty face tunnel is tunneled, and before stope exploitation finishes
Complete connection roadway workface prepares, and stopping surface of then moving restarts new circulation, until entire exploiting field exploitation section is whole
It has been adopted that, tradition exploitation arrangement.In order to safeguard the stabilization of lower curtate subsequent duty face back, using staying the coal for setting one fixed width
Column forms the irretrievable situation of coal column resource, does not meet the demand of new period China's energy development change.
Traditional recovery method of coal column is stayed to be brought using three lanes of one side pick, four lanes, five lanes in current broadwall
The wasting of resources it is more, high production cost, the low realistic problem of production efficiency, it is necessary to propose a kind of new coal-mining method.
Summary of the invention
To overcome the problems of the prior art, the purpose of the present invention is to provide a kind of big coal column drivings without coal pillar mining
Coal-mining method.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of big coal-mining method of the coal column driving without coal pillar mining, which is characterized in that for three lane systems, five lane four lane Zhi Huo
Working face processed, the distance of protection coal pillar is 30m or more between working face lane, while belt lane is located at outermost, and utilization is stayed along sky
Lane technology or the lane Qie Dingliu technology carry out the tunnel for staying lane to be next working face to belt lane, to realize this working face
Coal column this working face lane is all recycled when back production.
A further improvement of the present invention lies in that three lane working faces include positioned at the belt lane of working face side and positioned at work

Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings..
Coal working face is generally made of three tunnels, four tunnels or five tunnels.For three lane systems, four lane systems or five
Lane working face, the distance of protection coal pillar is 30m or more between working face lane, while belt tunnel is located at outermost, and utilizes edge
The lane Kong Liu technology or the lane Qie Dingliu technology carry out the tunnel for staying lane to be next working face to belt lane；To realize this work
Coal column this working face lane is all recycled when making face back production.
Referring to fig. 4, three lane working faces include the belt lane 1 positioned at working face side and the positioned at the working face other side
One air return lane 3 is provided with the first air inlet 2, between the first air inlet 2 and belt lane 1 between belt lane 1 and the first air return lane 3
Distance be face length 1/6th Dao a quarter (30m or more).
Referring to Fig. 5, four lane working faces include the belt lane 1 positioned at working face side and the positioned at the working face other side
One air return lane 3 is provided with the first air inlet 2 and the second air return lane 5, and the first air inlet between belt lane 1 and the first air return lane 3
The distance between lane 2 and air return lane 1 are 1/6th Dao a quarter (30m or more) of face length, the first air return lane 3 and
The distance between second air return lane 5 is 1/6th Dao a quarter (30m or more) of face length.
Referring to Fig. 6, five lane working faces include the belt lane 1 positioned at working face side and the positioned at the working face other side
One air return lane 3 is disposed with the first air inlet 2, the second air inlet 6 and the second return air between belt lane 1 and the first air return lane 3
Lane 5, and the first air inlet 2 is 1/6th Dao a quarter (30m or more) of face length at a distance from belt lane 1,
First air return lane 3 at a distance from the second air return lane be face length 1/6th Dao a quarter (30m or more), second into
Air way 6 is 1/6th Dao a quarter (30m or more) of face length at a distance from the first air inlet 2.
Coal column between the working face lane of this working face is all recycled by coalcutter, drag conveyor, passes through gob side entry retaining
Technology or the lane Qie Dingliu technology stay the belt working face lane set to realize working face extraction as next working face lane
Alternate run.
The present invention is by the change to roadway layout and using edge air gallery technology or the lane Qie Dingliu technology to belt
Lane carries out staying lane being that the tunnel of next working face is prepared, thus between coal this working face lane when realizing this working face extraction
Column all recycles.Particular by the distance of protection coal pillar between increasing working face lane, become from 20m~30m in the prior art
30m or more, while belt tunnel is moved into outermost to realize.
Fig. 1 is working face tradition three roadways layout mode, when traditional handicraft back production, between belt lane 1 and the first air inlet 2
Protection coal pillar just has lost.But the arrangement of Fig. 4 in through the invention, fender is converted into working face coal column between realizing lane
The problem of, belt lane 1 is that belt lane is placed in outside, so as to recycle the protection coal between belt lane 1 and the first air inlet 2
Column.It is simultaneously that next roadway workface is prepared using edge air gallery technology or the lane Qie Dingliu technology.
Fig. 2 is the traditional four lane arrangements of working face, when the normal back production of traditional handicraft, then belt lane 1 and the first air inlet
2, the protection coal pillar between the first air return lane 3 and the second air return lane 5 just has lost, and the arrangement of middle Fig. 5 through the invention,
Then as can be seen that increasing protection coal pillar between belt lane 1 and the first air inlet 2, the first air return lane 3 and the second air return lane 5
Distance realizes the problem of fender between lane is converted into working face coal column, and belt lane 1 is placed in outside, so as to recycle belt
Protection coal pillar between lane 1 and the first air inlet 2, the first air return lane 3 and the second air return lane 5.Edge air gallery technology is utilized simultaneously
Or the lane Qie Dingliu technology is that next roadway workface is prepared.
As a same reason, Fig. 3 is the traditional five lane arrangements of working face, when the normal back production of traditional handicraft, belt lane 1 and first
Protection coal pillar between air inlet 2, the first air inlet 2 and the second air inlet 6, the first air return lane 3 and the second air return lane 5 just loses
?.By the arrangement of Fig. 6, belt lane 1 and the first air inlet 2, the first air return lane 3, the second air inlet 6, second are increased
The distance of protection coal pillar between air return lane 5, realizes the problem of fender between lane is converted into working face coal column, and belt lane 1 is skin
Band lane is placed in outside, can be recycled using three protection coal pillars of the present invention.Edge air gallery technology or the lane Qie Dingliu are utilized simultaneously
Technology is that next roadway workface is prepared.
