Embodiment 2
[0036] Embodiment 2: When the catastrophe occurs on the air return side of the air path A, the upper and middle horizontal damper 8 is opened, and the upper and middle inlet fan 3, the lower and middle inlet fan 3' and the upper and middle return fan 5 are used for normal ventilation, and the lower and middle section Return air fan 5' closing mode.
[0037] The specific operation implementation steps are:
[0038] (1) with embodiment 1;
[0039] (2) Check the upper and middle section air intake fan 3, the lower middle section air intake fan 3', the upper and middle section return air fan 5 and the lower and middle section return air fan 5' anti damper, and set the fan remote centralized monitoring platform 15 to the remote control state;
[0040] (3) Close the lower middle stage return air fan 5 ' on the fan remote centralized monitoring platform 15;
[0041] (4) Under the new ventilation state, carry out the detection of the operating conditions of the ventilation system, d...
Embodiment 3
[0043] Embodiment 3: When the catastrophe occurs on the air return side of the air path B, open the upper and middle horizontal damper (8), and use the upper and middle inlet fan (3), the lower and middle inlet fan (3') and the lower and middle return fan (5') normal ventilation, and the upper and middle return air fan (5) is closed.
[0044] The specific operation implementation steps are:
[0045] (1) with embodiment 2;
[0046] (2) with embodiment 2;
[0047] (3) Close the upper and middle return air fan 5 on the fan remote centralized monitoring platform 15;
[0048] (4) Under the new ventilation state, carry out the operating condition detection of the ventilation system, detect the wind speed, air volume and wind direction of the wind lane 4 in the upper middle section and the wind lane 4' in the lower middle section, and detect the return air volume of the return air fan 5' in the lower middle section;
[0049] 5) After step (4) is completed, the anti-wind test is ov...

Abstract
The invention discloses a ventilation system capable of quickly realizing multi-stage fan station reverse ventilation of an underground metal mine. The system comprises a downcast shaft (1), an air return shaft (7), a fan remote centralized monitoring platform (15) as well as an upper middle-stage horizontal roadway and a lower middle-stage horizontal roadway with two ends communicating with the downcast shaft (1) and the air return shaft (7) respectively, wherein an upper middle-stage air inlet fan (3), an upper middle-stage horizontal air door (8) and a lower middle-stage air return fan (5') are sequentially arranged in the upper middle-stage horizontal roadway, and a lower middle-stage air inlet fan (3') and a lower middle-stage horizontal air door (8') are sequentially arranged in the lower middle-stage horizontal roadway; a lower middle-stage air return raise (9') is also arranged between a lower middle-stage air use roadway (4') and a lower middle-stage air return fan station roadway (6'); an upper middle-stage air return fan station roadway (6) is arranged at the upper part of the upper middle-stage horizontal roadway. The fan remote centralized monitoring platform (15) quickly starts, stops and reversely rotates fans in case of a catastrophe, the multi-stage fan station ventilation system can realize quick and reliable reverse ventilation.
Description
technical field [0001] The invention belongs to the technical field of metal underground mine ventilation, and in particular relates to a multi-stage machine station ventilation system of an underground metal mine. Background technique [0002] The working face of underground mining has a narrow space, the working face is constantly changing, and the dust and toxic and harmful gases generated during the mining operation will pollute the working face environment, especially in large-scale mechanized mines or mines with poor underground geological conditions. Once a fire occurs in the underground mine, it will It directly threatens the production under the mine and the life safety of workers. Mine ventilation provides a basic guarantee for mine safety production. [0003] Mine backwind is an important disaster relief measure to control wind flow in order to reduce the scope of disaster damage when a mine disaster occurs, especially in the event of a fire. By quickly realizing...
