Safety technical measures for air regulation of standby mining face

according to the production demand of mine safety, it is necessary to stop regulating the ventilation system of 13031 standby working face. In order to ensure safety during the period of ventilation system regulation, the following Enron technical measures are specially formulated:

1. The time of ventilation system regulation is set as: 8:00 on February 24

2. The general maintenance team is responsible for the task of ventilation and fragmentary regulation, so it is not necessary to select the channel address. The ventilation Department is responsible for the task of supervision and inspection during ventilation and fragmentary regulation, the comprehensive regulation room is responsible for the details of ventilation and fragmentary regulation, and the rescue team is responsible for the emergency preparation during ventilation and fragmentary regulation

3. Before the ventilation and fragmentary adjustment, the general maintenance team was responsible for the construction of two temporary air doors at the platform of 13 second winch and at the place where the roadway support in 13031 air bridge was free of defects, slags, roof falls and sundries. The air doors were overlapped with fish scales, which were roughly plastered or pointed with plaster, and the construction standard met the requirements of quality standardization

4. Before the ventilation and fragmentary adjustment, the gas inspector on duty shall be responsible for evacuating all staff in the 13031 standby task face to the full air pressure ventilation roadway of the track roadway. Before the ventilation and fragmentary adjustment is completed, no staff is allowed to enter the task face to stop their work

5. The setting of warning points for ventilation fragmentary adjustment is as follows: 13031 upper alley entrance and 13031 lower alley entrance, which are guarded by special personnel as assigned by the general maintenance team

6. In case of ventilation fragmentary adjustment, the general repair team shall first close the air door in the 13031 air bridge, then open the air door in the upper lane of 13031, and close the air door on the platform of the second winch of 13 after the air path is cleared. After the adjustment, the air flow of the 13 mining area is below the line:

7. After the air flow adjustment is normal for 30 minutes, the ventilation Department of Enron shall stop measuring the air flow of the 13031 task surface, ensuring that the air flow of the standby 13031 task surface meets the production demand

8. After the ventilation system is adjusted, the ventilation Department of Enron will report the completion of 13031 ventilation system adjustment to the filter adjustment room with the infarct instigator, and the general repair team will be responsible for 13031. From this, it is concluded that the main function of the spring testing machine is the tension, pressure, displacement, and Pull the spline until the spline appears fracture stiffness and other strength experiments and analysis. The old ventilation door in the upper roadway is abolished

9. Matters not covered must be performed in strict accordance with the relevant provisions of the coal mine safety regulations
