Detailed description of the invention
To be described in further detail the embodiment of the present invention below.
High-temperature mine method of ventilation of the present invention, its preferably detailed description of the invention comprise:
Concentrate air intake, disperse air return method;
Windy well exhaust ventilation mode.
Initial stage exploiting field all adopts the main air intake of auxiliary shaft, the auxiliary air intake of main shaft and the large lane of main air intake to concentrate the air intake mode of air intake with extending exploiting field, and return air is carried out by central industry square ventilating shaft in initial stage exploiting field, extends exploiting field and carries out return air by border, field with "nine squares" ventilating shaft;
Main ventilation fan is arranged on respectively central industry square return air well head and border, field with "nine squares" return air well head goes out, and full mine adopts exhaust ventilation mode.
High-temperature mine method of ventilation of the present invention, is applicable to the full mine ventilation of high-temperature mine, can effectively alleviate the high warm evil in down-hole by the method.
High-temperature mine method of ventilation of the present invention is the method for ventilation that a kind of concentrated air intake, dispersion air return method combine with windy well pull-out type, be specially: 1. initial stage exploiting field all adopts the main air intake of auxiliary shaft, the auxiliary air intake of main shaft and the large lane of main air intake to concentrate the air intake mode of air intake with extension exploiting field, return air is carried out by central industry square ventilating shaft in initial stage exploiting field, extends exploiting field and carries out return air by border, field with "nine squares" ventilating shaft; 2. main ventilation fan is arranged on respectively central industry square return air well head with border, field with "nine squares" return air well head goes out, full mine employing exhaust ventilation mode.
Specific embodiment:
As shown in Figure 1, freshly distinguished and admirablely enter down-hole by downcast 1 (auxiliary shaft), enter down-hole through shaft station and concentrate the large lane 5 of air intake, enter the initial stage exploiting field air intake of going up a hill and go up a hill 7 by initial stage 10 parking lots, bottom 6, exploiting field of going up a hill, enter the initial stage exploiting field coal-face intake entry 9 of going up a hill by the initial stage exploiting field middle yard 8 of going up a hill, enter the initial stage exploiting field coal-face tailgate 12 of going up a hill by work plane 11, the initial stage of the entering exploiting field return air of going up a hill goes up a hill 14, import the large lane 26 of centralized return air system, finally get back to ground by nave ventilating shaft 3; Simultaneously, freshly distinguished and admirablely enter the initial stage exploiting field air intake of going down the hill by the large lane 5 of concentrated air intake and go down the hill 18, enter the initial stage exploiting field coal-face intake entry 20 of going down the hill by the initial stage exploiting field middle yard 19 of going down the hill, enter the initial stage exploiting field coal-face tailgate 22 of going down the hill by work plane 21, the initial stage of the entering exploiting field return air of going down the hill goes down the hill 25, import the large lane 26 of centralized return air system, finally get back to ground by nave ventilating shaft 3.Equally, extend the exploiting field 27 of going up a hill, the exploiting field 28 of going down the hill is all by concentrating air intake large lane 5 air intakes, by after work plane separately, weary wind imports the extension large lane 29 of centralized return air system, exploiting field, finally gets back to ground by border ventilating shaft 30.
