Embodiment 2

[0057] 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.

[0058] The specific operation implementation steps are:

[0059] (1) with embodiment 1;

[0060] (2) Check the upper and middle inlet fan 3, the lower and middle inlet fan 3', the upper and middle return fan 5, and the lower and middle return fan 5', and set the fan remote centralized monitoring platform to the remote control state;

[0061] (3) Turn off the lower and middle section return air fan 5' on the fan remote centralized monitoring platform;

[0062] (4) Under the new ventilation state, carry out the detection of the operating conditions of the ventilation system, detect the wind speed, air volume and wind direction of ...

Embodiment 3

[0064] 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.

[0065] The specific operation implementation steps are:

[0066] (1) with embodiment 2;

[0067] (2) with embodiment 2;

[0068] (3) Close the upper and middle return air fan 5 on the fan remote centralized monitoring platform;

[0069] (4) Under the new ventilation state, the operating conditions of the ventilation system are detected, the wind speed, air volume and wind direction of the upper and middle air lane 4 and the lower middle air lane 4' are detected, and the return air volume of the lower and middle return fan 5' is detected;

[0070] 5) After step (4) is completed, the anti-wind test is over; and then turn on the upper and middle...

Abstract

The invention discloses an inverted ventilation test method for a multi-stage fan station ventilation system in an underground metal mine. The adopted multi-stage fan station ventilation system is composed of a downcast shaft (1), a return shaft (7), an upper middle segment horizontal roadway, a lower middle segment horizontal roadway, a middle segment air intake fan (3), an upper middle segment horizontal air door (8), a lower middle segment return fan (5'), a lower middle segment air intake fan (3'), a lower middle segment horizontal air door (8'), a lower middle segment return air raise (9') and an upper middle segment return air raise (9). The multi-stage fan station ventilation system is divided into an air intake side and an air return side according to the demarcation point of the positive relative static pressure and the negative relative static pressure of an air path, and what kind of inverted ventilation mode is selected according to the location where a catastrophe occurs. According to the method, a basis is provided for inverted ventilation mode selection of an inverted ventilation test of the multi-stage fan station ventilation system, the inverted ventilation process is easy to operate, whole-mine inverted ventilation can be quickly achieved, and the quick responsiveness of mine inverted ventilation serving as an emergency rescue measure of the mine is fully exerted.

Description

technical field [0001] The invention belongs to the technical field of metal underground mine ventilation, and in particular relates to an underground metal mine anti-wind test system and method. Background technique [0002] Mine backwind is an important disaster relief measure to control wind flow when a disaster (especially a fire) occurs in a mine. The "Safety Regulations for Metal and Nonmetal Mine" and "Technical Specifications for Ventilation of Metal and Nonmetal Underground Mine - Ventilation System" stipulate that the mine should conduct a reverse wind test at least once a year, and measure the air volume after the main wind path reverses the wind. [0003] The metal mine ventilation system gradually developed from large main fan ventilation to multi-stage machine station ventilation at the end of the last century. At present, underground metal mines adopt multi-stage machine station ventilation. Compared with the large main fan ventilation system, the number of mu...
