Abstract
The invention discloses a recycling-period ventilating structure for a coal face and a construction method of the recycling-period ventilating structure. The ventilating structure comprises a metal net, wind guide pipes and a row of wooden pillars, wherein the metal net is laid under a top plate of a fully-mechanized coal mining surface and covers all hydraulic brackets, the wind guide pipes are arranged at a coal wall support, and the wooden pillars are tightly arrayed between the wind guide pipes and a caving top plate. According to the recycling-period ventilating structure, after the hydraulic brackets are retracted, the top plate of an unprotected area sinks, the wind guide pipes are not extruded to deform by virtue of a triangular space formed by the wind guide pipes, the obstruction effect of the wooden pillars and the shielding effect of the metal net, and a wind channel is formed, so that the normal ventilation during a recycling period is guaranteed, and the problems that a triangular area is blocked and the effective ventilation cannot be guaranteed because the formed triangular area is relatively small or the top plate is crushed due to the high pressure of the top plate are solved. The recycling-period ventilating structure further has the characteristics of being simple in structure, low in cost and convenient, rapid and safe to construct.
Description
Technical field
The present invention relates to a kind of coal-face payoff period aeration structure and its construction method, belong to coal-mining technique field.
Background technology
During underground coal mine coal-face is reclaimed at present, usually after face hydraulic support withdrawing is adopted, apply in empty top zone
Work intersecting parallels grillage installs pin and individual prop by top plate supporting, forms airflow channel, it is ensured that ventilation, satisfaction scene makes
With requiring.When partially recycled face roof pressure is larger, construction cross grillage or installs pin and be unable to effective support top
Plate, easily causes empty top zone domain to close, airflow channel is blocked；During the roof cracking of recovery operation face, the spoil that top board leaks down is easy
Airflow channel is blocked, normal ventilation is affected.
The content of the invention
The technical problem to be solved in the present invention is：A kind of construction method of coal-face payoff period aeration structure is provided,
Easily will so that the spoil leaked down when effective support top board causes airflow channel blocking or roof cracking is unable in solution prior art
Airflow channel is blocked and affects the normal problem divulged information.
The technical scheme that the present invention takes is：A kind of coal-face payoff period aeration structure, including wire netting, guide duct
And pin, wire netting is laid under the top board of fully mechanized coal face and covers all hydraulic support, and guide duct is arranged at rib side, is being led
Airduct and it is caving between top board and lays the compact arranged pin of a row.
A kind of construction method of coal-face payoff period aeration structure, including lay wire netting, withdraw hydraulic support, paving
If ventilating duct and pin, which comprises the following steps that：
（1）When fully mechanized coal face back production is to design attitude, start layer of metal net, wire netting are laid between hydraulic support and top board
All hydraulic support is covered, until stopping adopting line, is fixedly connected between adjacent two wire nettings；
（2）After work surface withdraws two hydraulic supports, in rib side laying guide duct, adjacent two guide ducts junction is using fixation
Connection；
（3）After the completion of guide duct laying, in guide duct and row's pin of constructing is caving between top board；
（4）Repeat step（2）-（3）, two hydraulic supports are often withdrawn, guide duct and pin construction working is repeated once, until returning
Withdraw from all hydraulic support.
Beneficial effects of the present invention：Compared with prior art, the present invention after hydraulic support withdrawing, push up by empty top zone domain
Plate sinks, and as the triangular space for itself being formed adds the effect of blocking of the iris action and wire netting of pin, guide duct is not
Can be deformed, form airflow channel, it is ensured that the normal ventilation during recovery, after solving hydraulic support withdrawing, because of top
Plate pressure causes greatly the Delta Region of formation itself less or roof cracking causes Delta Region to be blocked, it is impossible to ensure effective
The problems such as ventilation, the present invention also have simple structure, low cost, safe convenient and quick construction the characteristics of.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the present invention.
Implement:1：As shown in Figure 1-Figure 3, a kind of coal-face payoff period aeration structure, including wire netting 2, guide duct 3
With pin 4, wire netting 2 is laid under the top board of fully mechanized coal face and covers all hydraulic support 1, and guide duct 3 is arranged at rib side,
The compact arranged pin of a row 4 is laid in guide duct 3 and being caving between top board.
Embodiment 2：A kind of construction method of coal-face payoff period aeration structure, including lay wire netting 2, withdraw liquid
Pressure support 1, laying ventilating duct 3 and pin 4, which comprises the following steps that：
（1）When fully mechanized coal face back production is to design attitude, start in hydraulic support（1）Layer of metal net 2, gold are laid between top board
Category net 2 covers all hydraulic support 1, until stopping adopting line, is fixedly connected between adjacent two wire nettings 2；
（2）After work surface withdraws two hydraulic supports 1, in rib side laying guide duct 3, adjacent two guide ducts, 3 junction is adopted
With being fixedly connected；
（3）After the completion of guide duct 3 is laid, in guide duct 3 and row's pin 4 of constructing is caving between top board；
（4）Repeat step（2）-（3）, two hydraulic supports 1 are often withdrawn, guide duct 3 and 4 construction working of pin is repeated once, directly
To having withdrawn all hydraulic support 1.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention, therefore, protection scope of the present invention should be defined by the scope of the claims.
