Determination of coal mine air quantity of ventilation safet
Date:2013-11-22 Hits:
Coal mine ventilation is a powerful guarantee for coal mine safety, mine air quantity determination is an important work of coal mine ventilation relationship. Determination of the need to do a lot of mine air.
1, wind member must be held by personnel trained, certificates.
2, the mine must have a sufficient number of ventilation safety testing instrument. Inspection unit safety instrument wind instrument must be authorized by the state to before the use of calibrated.
3, coal mine, in return airway, each level, each wing and the panel, and in return airway intake must construct permanent standardized wind station, each site should have a wind board, each site must be selected in the roadway section uniform, before and after 5m no obstacle, turning, the undulating, empty, empty top watering place for.
4, the panel, a wing and total return air lane wind monitoring station should be set for each wind speed sensor, the results should be proofread and wind speed sensor, exceeding the prescribed error, should be promptly reported the ventilation Department, responsible for monitoring electrical calibration ventilation Department notice.
5, the ventilation Department once every ten days throughout the mine air quantity determination, to fill in the cards, using wind place record, making wind statements to the relevant units.
6, the ventilation department according to the result of observation time, the required air volume adjustment using wind place timely take corresponding measures for the adjustment of the air.
