Studding；
4th ore bed Pre-control roof construction step, Y digs one article of drilling drift of chisel in the width direction in the 4th ore bed, and tilts
Upwards then construction slot raise freely expands side between the first ore bed towards two sides with slot raise to the top plate of the first ore bed
At column；
And segmentation mining area's stages of mining, to the segmentation mining area 400 in the 4th ore bed, third ore bed and the second ore bed
It is exploited using sublevel drilling segmentation ore removal mining methods.
The 4th above-mentioned ore bed studding is arranged in segmentation mining area 400 in the second ore bed, third ore bed and the 4th ore bed,
And will exploitation backfill after third ore bed as segmentation mining area 400 exploit when protection top, equally, can be greatly decreased to divide
The usage amount of support bracket when section mining area 400 exploits saves production cost, improves the safety exploited to segmentation mining area 400
Property.
Moreover, because the height of segmentation mining area 400 is larger, in order to further increase when segmentation mining area 400 exploits
Safety adds Pre-control roof in the top layer of segmentation mining area 400 and the abutting of the first ore bed, starts Pre-control roof engineering of constructing.It is first
First with layering drift from disk on mineral building intermediate vertical orebody trend one back production drilling drift to ore body of construction, along ore body
Upper disk ore-rock boundary oblique constructs slot raise to the artificial roof of first layer upwards, then with slot raise be freely towards
Two sides expand side until artificial intervening pillar position.Supporting is carried out to upper armor rock in time with the driving in tunnel in work progress.Root
According to the degree of crushing of upper armor rock, steel mesh supporting can be added using anchor and spray net or anchor cable.Pass through Pre-control roof work of constructing in advance
Journey can guarantee not occurrence of large-area slump during being segmented ore removal of upper armor rock, and two sides and top plate have artificial intervening pillar respectively
With the protection of artificial roof, and be based on above-mentioned condition, design determine segmentation mining area 400 using sublevel drilling segmentation ore removal mining
Method.Dead zone is filled immediately after back production, avoids the too long generation country rock slump of armor rock exposure duration.
In addition, more preferred in the optinal plan of the present embodiment:
First bed top, the first studding, the second studding, third studding and the 4th studding respectively include respective steel mesh
Skeleton pours filling material filled with classified tailings in steel mesh skeletal internal.
The construction that reinforcing bar network framework bonus point grade tailings pours, under the precondition that not only can guarantee its supporting intensity, moreover it is possible to
Reduce the economic cost of manufacture of the first bed top, the first studding, the second studding, third studding and the 4th studding.
In addition, more preferred in the optinal plan of the present embodiment:
In the first bed top construction step, to a plurality of Strike drift by the way of digging one at interval of three diggings
110 carry out back production.
It can avoid in this way when carrying out back production the first bed top of construction to Strike drift 110 because ore shakiness is to edge
110 two sides of arteries and veins route carry out explosion bring vibration influence simultaneously.
In addition, more preferred in the optinal plan of the present embodiment:
The layering drift that X extends along its length is respectively set in each ore bed, and in each subsection setup
One stope connection roadway, stope connection roadway will be layered drift and be connected to segmentation drift.Each ore bed has one point
Layer drift and by the connection of stope connection roadway, the mineral products of such structure not only each ore bed of convenient transportation, but also
Ore removal route can also be simplified.
In addition, more preferred in the optinal plan of the present embodiment:
It is laid with classified tailings on the bottom surface corresponding with the layering drift of the 4th ore bed of third ore bed and pours filling
Expect reinforcing bar enhancement layer.

It is relatively large, and the layering drift sequence of construction of the 4th ore bed is later than the filling of third layering drift again, in order to protect
The safety for demonstrate,proving the 4th layering drift, corresponding position is laid with steel mesh above the 4th layering drift.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
