Description
Technical field
The present invention relates to a kind of thermal post_buckling district ventilation technology, particularly relate to a kind of high-temperature mine district ventilation method.
Background technology
District ventilation system is the main component units of mine ventilation system, is the important component part of District production system.The whether reasonable allocation of the amount of air not only affected in exploiting field of district ventilation system, distinguished and admirable control when having an accident, completing smoothly of production, and the ventilation quality and the safe condition that have influence on full mine.Due to electromechanical equipment and personnel relatively concentrate, the more high factor of country rock temperature, be heated workplace that evil threatens, down-hole mainly concentrates on and adopts driving face in exploiting field.Therefore, rational, district ventilation method that is that be conducive to lowering the temperature is the prerequisite of mine safety production, is also that work plane refrigeration cool-down appropriate measures effectively ensure.
In working surface production layout, the application of the double-vane mode of production is comparatively extensive, but distinguished and admirablely in this kind of layout type all turns back with coal stream, and ventilation routes is longer, is unfavorable for cooling; Face moving number of times is relatively many.
In prior art, in the district ventilation method of extensive use, the selection on the upper (lower) mountain of exploiting field air intake and the upper (lower) mountain of return air mainly contains two kinds: 1. track upper (lower) mountain air intake, transporter upper (lower) mountain return air; 2. transporter upper (lower) mountain air intake, track upper (lower) mountain return air.
At least there is following defect in above-mentioned prior art:
Transporter is gone up a hill air intake, because wind direction is contrary with coal flow path direction, easily causes coal dust to fly upward; The gas that coal discharges in transportation, can make the gas of air intake and Dust Concentration increase, affect the safety and sanitation condition of work plane; The heat that conveying equipment distributes, makes air intake temperature raise; Need to install air door in the parking lot, bottom on mountain in orbit, transport mine car dealing is herein frequent, needs to strengthen management, prevents Air escape branch.During work plane employing ascensional ventilation mode, the air intake in exploiting field need be directed at air intake lane, bottom, exploiting field, then enter work plane, the route flowed through is longer, and distinguished and admirable meeting heats up due to compression and ground temperature heating; The heat that in tunnel, electromechanical equipment distributes also add distinguished and admirable in, be unfavorable for cooling.
Summary of the invention
The object of this invention is to provide a kind of high-temperature mine district ventilation method, the method is applicable to the district ventilation of Climatic regionalization mine, can realize the aeration-cooling effect that high-temperature mine exploiting field is good.
The object of the invention is to be achieved through the following technical solutions:
High-temperature mine district ventilation method of the present invention, comprising:
The work plane in exploiting field adopts single-blade production distribution mode;
Adopt ginney or go down the hill, the air inlet mode of gallery air intake, freshly distinguished and admirablely enter work plane through intake entry;
Adopt belt-conveying gallery, transporter goes up a hill or the air return method of return air of going down the hill, enter district haulage conveyer by the weary wind of work plane through belt-conveying gallery and go up a hill or go down the hill to carry out return air;
Coal-face adopts downward ventilation mode, and wind direction is consistent with coal flow path direction.
As seen from the above technical solution provided by the invention, the high-temperature mine district ventilation method that the embodiment of the present invention provides, because the work plane in exploiting field adopts single-blade production distribution mode; Adopt ginney or go down the hill, the air inlet mode of gallery air intake, freshly distinguished and admirablely enter work plane through intake entry; Adopt belt-conveying gallery, transporter goes up a hill or the air return method of return air of going down the hill, enter district haulage conveyer by the weary wind of work plane through belt-conveying gallery and go up a hill or go down the hill to carry out return air; Coal-face adopts downward ventilation mode, and wind direction is consistent with coal flow path direction, is applicable to the district ventilation of Climatic regionalization mine, realizes the good aeration-cooling effect in high-temperature mine exploiting field by the application of the method.

Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
High-temperature mine district ventilation method of the present invention, its preferably detailed description of the invention comprise:
The work plane in exploiting field adopts single-blade production distribution mode;
Adopt ginney or go down the hill, the air inlet mode of gallery air intake, freshly distinguished and admirablely enter work plane through intake entry;
Adopt belt-conveying gallery, transporter goes up a hill or the air return method of return air of going down the hill, enter district haulage conveyer by the weary wind of work plane through belt-conveying gallery and go up a hill or go down the hill to carry out return air;
Coal-face adopts downward ventilation mode, and wind direction is consistent with coal flow path direction.
Adjacent front exploiting field and rear exploiting field are all arranged as the single-blade mode of production.
Fresh distinguished and admirable by the large lane of concentrated air intake, front exploiting field ginney is entered by parking lot, bottom, front exploiting field, front exploiting field coal-face track gallery is entered again by front exploiting field middle yard, by entering front exploiting field coal-face belt-conveying gallery after work plane, enter front district haulage conveyer to go up a hill, import the large lane of centralized return air system, finally get back to ground through mine total return air well;
