Directional blasting is the use of explosive energy on the surrounding medium, so that the exploded object according to people's requirements, directional collapse in a controlled manner. As an engineering auxiliary means, directional blasting is widely used in open-pit mining, underwater operations, urban construction, bridge demolition, highway and railway construction and other fields. There are several main reasons why directional blasting does not affect the surrounding buildings:
1. Accurate positioning and calculation.
Directional blasting requires precise calculations and design, including considerations such as dosage, charge structure, initiation network, topography and geology. Through the precise control of the energy distribution of the explosives, it is ensured that the blasting energy can effectively act on the target object, causing it to collapse in a predetermined direction, while reducing the disturbance to the surrounding environment. Before carrying out directional blasting, professionals will conduct a detailed survey of the surrounding environment, assess the possible impact of blasting on the surrounding buildings, and take appropriate protective measures.
2. Reasonable charge structure and initiation network.
The charge structure and initiation network used in directional blasting are carefully designed to ensure that the explosive energy is released in a specific time and space to achieve the best blasting effect. A reasonable charge structure can control the diffusion range and speed of the ** product, and reduce the impact and damage to the surrounding environment. Precise control of the initiation network ensures that the explosives detonate at the optimal moment, reducing the impact on surrounding buildings.
3. Effective protective measures.
In order to ensure that the directional blast does not affect the surrounding buildings, a series of protective measures are usually taken. For example, set up shock-absorbing ditches and shock-absorbing barriers around the building to reduce the damage to the building caused by the shock wave and flying rocks. At the same time, the surrounding buildings are reinforced or protected to ensure their safety before directional blasting is carried out.
4. Experienced professionals.
Directional blasting requires a team of experienced professionals with the theoretical knowledge and practical experience to accurately assess the impact of blasting on the surrounding environment and take appropriate measures to control it. During the construction process, professionals will pay close attention to the changes in the surrounding environment, and make adjustments and optimizations according to the actual situation to ensure the safety and smooth progress of the blasting operation.
The key to a directional blast that does not affect the surrounding buildings is precise positioning and calculation, a reasonable charge structure and initiation network, effective protective measures, and experienced professionals. In the scientific design and rigorous construction process, directional blasting can effectively control the impact on the surrounding environment and realize the smooth progress of engineering construction.
