How many levels of blasting qualification have been set for mountain blasting?

The level of mountain blasting is determined according to the scale and complexity of mountain blasting engineering, which is not directly related to individual blasting qualification. Generally speaking, mountain blasting is divided into primary, secondary and tertiary levels.

First-class mountain blasting refers to a very simple mountain blasting project, such as small-scale blasting demolition, which is usually handled by experienced personnel.

Secondary mountain blasting refers to a slightly larger and more complicated mountain blasting project, such as leveling the foundation and arranging the shot points, which needs to be carried out by a blaster with certain professional knowledge and skills.

Three-level mountain blasting refers to a large-scale and technically difficult mountain blasting project, such as a large tunnel project, which needs a professional blasting team with high blasting qualification and rich practical experience to complete.

Therefore, the level of blasting qualification is not determined according to the level of mountain blasting, but according to the relevant blasting professional qualification certificate obtained by individuals. Different countries and regions have different requirements for blasting qualification. Generally speaking, to become a qualified blaster, you need to go through relevant training, pass relevant examinations and obtain qualification certificates.

It should be noted that due to different regulations and standards in different regions and countries, the specific blasting qualification requirements and grading may be different. If you want to know the blasting qualification requirements in a certain area, I suggest you consult the relevant local functional departments or professional institutions.
