Blasters include blasters, safety officers and storekeepers. During the training, in order to ensure the training effect of blasting operators and not affect the production of enterprises, the public security brigade reasonably arranged the blasting operators of all units to participate in the training in view of the actual situation of many blasting operators and heavy blasting engineering tasks, so as to facilitate the production of enterprises.
Training activities are generally conducted by classroom teaching, on-site operation and on-site demonstration. The training contents mainly include laws and regulations, explosive properties, initiation methods, basic blasting knowledge and commonly used drilling equipment, blasting methods and operation techniques, and safety management of blasting equipment.
Urban building blasting
The core idea of urban building blasting is to destroy only the key load-bearing structure, make the building collapse in a controlled way, break it into small pieces as much as possible under the action of gravity, and minimize the impact on the surrounding environment. If there are houses and subway lines around, higher requirements are put forward for blasting demolition.
There are three ways to demolish the mainstream by blasting: directional collapse, in-situ collapse and span-by-span collapse. Directional collapse is to blow a triangular incision in the lower part of the building, which makes the building fall in the direction of the incision, hit the ground and disintegrate.
