Description
Technical field
The present invention relates to a kind of return air to detour, in particular to a kind of novel load-carrying air crossing and return air detour piercing technique, belongs to
In mine technology field.
Background technique
Field with "nine squares" developing uses " major and minor gentle slope inclined shaft+return air shafts " combined development, central block form ventilation, loopful section glue
Band conveyer transports, and the upper and lower assistant conveyance of well uses railless free-wheeled vehicle, and it is coal that Longde coal mine, which shows back production coal seam, and three main entrys occupy
In be arranged in the middle part of field with "nine squares", both wings exploitation, 209 return air detour to be tunneled using continuous milling machine, the wide 5.2m in tunnel, high 3.6m.When driving
It needs to penetrate through with the auxiliary fortune main entry of coal and adhesive tape main entry respectively, conventional method is first normal perforation, and the later period, big gun pick was caunched again, is then constructed
Air crossing.
But existing 209 return air detours and caunches that project amount is big, risk is high, difficulty of construction is big, long in time limit there are the later period
And the problems such as coal east area assistant conveyance distance.
Summary of the invention
It detours piercing technique the purpose of the present invention is to provide a kind of novel load-carrying air crossing and return air, to solve above-mentioned background
The project amount of caunching proposed in technology is big, risk is high, difficulty of construction is big, long in time limit and coal east area assistant conveyance distance
The problem of.
To achieve the above object, the driving the invention provides the following technical scheme: a kind of novel load-carrying air crossing and return air detour
Technique, including coal return air main entry, one end vertical connection of the coal return air main entry and the lane Jiao Huilian, the lane Jiao Huilian it is another
End and the side vertical connection in the middle part of coal adhesive tape main entry, one end of the other side and the lane Fu Jiaolian in the middle part of the coal adhesive tape main entry are hung down
Direct-connected logical, the other end and the middle part vertical connection of the auxiliary fortune main entry side of coal, the auxiliary fortune main entry of coal in the lane Fu Jiaolian are another
One end vertical connection that the middle part of side and return air detour.
As a preferred technical solution of the present invention, the top in the lane Jiao Huilian and the junction of coal adhesive tape main entry is opened
Equipped with caunching.
As a preferred technical solution of the present invention, the inside caunched is fixed with air crossing, and the air crossing includes
Two mining i beams, two mining i beams are fixedly connected by installing bolt, and the top of the mining i beam is solid
Surely it is equipped with reinforcing steel bar cage, the outside of the reinforcing steel bar cage is cast with concrete layer.
As a preferred technical solution of the present invention, the return air detour piercing technique the following steps are included:
S1: it constructs when driving in strict accordance with design grade, it is ensured that and stay and set when the auxiliary fortune main entry of coal and the perforation of coal adhesive tape main entry
Good step, when construction in later period air crossing, directly can be laid with mining i beam on the step of tunnel two sides, not need in addition to build brick wall,
With the auxiliary fortune main entry perforation of coal at set up firm platform using sleeper in advance, and stayed under platform and set pedestrian space, side
Just pedestrian, ventilation.
S2: with after coal auxiliary fortune main entry perforation, continuous milling machine directly passes through the platform set up and offers caunches, across the auxiliary fortune of coal
Continue to tunnel according to design grade after main entry, be penetrated through until with coal adhesive tape main entry, this technique is not needed from the auxiliary fortune main entry opening of coal
The lane main entry Fu Jiaolian is tunneled, the influence to mining assistant conveyance is reduced.
S3: by 209 return air detour common air crossing be optimized for driving air crossing, air crossing bottom be laid with mining i beam, construction
When in mining i beam bottom install template, reinforcing steel bar cage is then installed above mining i beam, reinforcing steel bar cage uses iron wire
It is fixed on mining i beam, it is highly 180mm that reinforcing steel bar cage is formed using 20# steel bar meter, mesh width 200mm.
S4: being punched in the middle part of I-steel both ends, be bolted together using M30, and every mining i beam two sides use
On bottom plate, earth anchor is welded on I-steel earth anchorage, and earth anchor specification Φ 18 × 1200mm screw-thread steel uses CK2360 type anchor
Gu agent full length fastening is fixed on top plate in the middle part of the mining i beam that air crossing two sides are laid with using anchor cable and M30 flower basket bolt,
Finally use 400mm thickness C30 concrete layer one-piece casting.
