1. The operation of underground explosives must strictly implement the "one gun and three inspections" system and the "three-person interlocking and shooting" system.
2. "One shot and three inspections" means that before the shot, before the shot, after the shot, the gas concentration in the wind flow of 20m near the shooting position must be checked. The gas concentration exceeds 1%, and the shot is not allowed.
3. The Ventilation Section is responsible for the installation of a portable methane detection alarm for the downhole full-time blaster.
4. When a full-time blaster carries a portable methane detection alarm device before entering the well, he must receive the “one shot and three inspection†chart. After arriving at the operation site, the blaster fills in the specific content according to the relevant requirements, and should have the on-duty foreman and gas inspector. The signature, when the full-time blaster pays off the portable methane detection alarm after work, the chart is handed over to the staff of the instrument transceiver room.
5. The ventilation department must set up a special person to carefully review the contents of the “one shot and three inspections†chart, timely discover and correct various problems, and sign (seal) to save. For teams that have repeatedly corrected or who do not fill out the chart as required, and full-time blasters, fines are imposed.
6. Regardless of whether the gun is fired or not, you must carry and fill out the "one shot three check" chart. If the shooting operation is not carried out on duty, the words "The class has not been fired" are indicated in the chart.
7. The "three-person interlocking and shooting" system must be strictly enforced. The execution procedure is as follows: before the shooting, the full-time blaster will hand over the warning sign to the on-duty foreman. After the inspector counts the personnel, the guardian will send a warning, issue the gun command, and check the roof and support conditions. The card is handed over to the gas inspector (or security officer). Gas inspector (or security staff) to check gas, coal dust after passing his license to carry blasting blasting Blasters emit blasting the siren (to blow the whistle, shouted three times "blasting") were shooting, shooting after three The cards are returned to the original owner.
8. The safety officer is responsible for the supervision of the implementation process of the “one shot and three inspections†and “three-person interlocking and shooting†system. The gas inspector is responsible for guiding and supervising the filling of the “one shot and three inspections†chart.
9. The warning signs, command plates and guns are produced by the mine and distributed and managed by the ventilation department. The use of three-card personnel should be properly kept to prevent damage and loss, otherwise, it should be reissued in time.
10. Before firing, the team must disconnect all power from the return airflow, and the gas inspector can confirm the error before issuing the firing command.
11. After the shot is fired, the gas inspector must carefully check the gas in the working face and the return air flow, and confirm that the shooting position and the return air flow gas concentration are less than 1% before issuing a command to resume the power transmission.
