Environmental Protection Mine Blasting Process and Safety Precautions

As the preliminary preparation stage of mining, environmentally friendly mine blasting is particularly important. Standardized mine blasting must follow fixed procedures and pay attention to numerous matters.

The safety distance between mine blasting and personnel, equipment, and structures is mainly determined by factors such as blasting method, scale, terrain, and ground features. In particular, the safety distance for personnel must be carefully calculated to ensure the personal safety of all staff.

Mine Blasting Process: Mine blasting uses industrial explosives to break, compact, and loosen the target rock mass, which is a chemical explosion process. The explosion generates a large amount of heat, resulting in high overall risk, so production safety must be strictly observed.

Blasting operations must be performed by professional and qualified technicians. Improper operation by unqualified personnel can easily lead to safety hazards. Additionally, technicians must receive regular training to prevent violations of operating procedures.

Blasting operations sometimes produce large amounts of toxic gases. If these gases are not diluted and discharged in a timely manner, they will pose a significant threat to the safety of on-site personnel.

Flyrock refers to individual rock fragments ejected from the rock mass surface during blasting that travel long distances. This is mainly caused by excessive explosive charges or flyrock exceeding the safety allowable range. Therefore, it is essential to accurately calculate the charge weight and set appropriate safety distances during blasting.

Blasting materials are both company property and highly hazardous items. Strict management must be implemented: they must be transported using dedicated vehicles, shall not be lent out arbitrarily, and must be issued and used in quantified amounts for each operation.
