3. It is strictly prohibited to blast blastholes without sealing mud or with insufficient sealing mud. It is strictly forbidden to fire blasting blasts. It is strictly forbidden to use capping and padding. Every underground blasting operation must strictly implement the "three-person chain" blasting system, which consists of three persons: the blaster, the gas inspector, and the squad leader. 4. Strictly implement the blasting evacuation system.

5. Charge blasting is only allowed when the gas concentration in the wind flow within 20m of the blasting site is less than 1.

6. Each underground blasting operation shall be carried out by three persons: the blaster, the gas inspector and the squad leader. No operation shall be carried out without one person.

7. After blasting, after the smoke from the working surface has been blown away, the blasters, gas inspectors and team leaders must first inspect the blasting site to check ventilation, gas, coal dust, roofs, supports, and Production can only be resumed when there are no blind or damaged cannons, etc., and everything is in compliance with regulations.
