Introduction
Drilling and blasting is a method of excavation used in constructing tunnels and underground structures. This process has been used since ancient times, but it has evolved over the years and is regularly used in modern engineering projects. In this article, we will discuss the drilling and blasting process, its advantages and disadvantages, and its importance in modern engineering works.
Drilling and Blasting Process
Drilling and blasting is a process of excavation where a hole is drilled into a rock surface in order to make it easier to break it into pieces. The hole is filled with explosives and detonated, which causes the rock to be broken apart so it can be moved or removed. This process is used in construction of tunnels, water supply systems, roadways, canals, and other underground installations.
Advantages
Drilling and blasting is one of the most economical and efficient methods of excavation. It eliminates the need for other heavy machinery such as bulldozers, resulting in significant cost savings. It is also considered to be an environmentally sound approach to excavation. When compared to other methods of excavation, it produces less dust, noise, and vibration. Furthermore, it is a very safe method of excavation and does not require as many workers on site as other excavation methods.
Disadvantages
Drilling and blasting is not without its disadvantages. One of the main drawbacks of this method is the cost involved. Drilling and blasting requires specialized equipment and skilled personnel, resulting in higher costs than other excavation methods. In addition, the use of explosives in this process can cause damage to nearby objects and buildings, resulting in the need for extensive preparations and additional safety measures.
Conclusion
Drilling and blasting is an important method of excavation used in modern engineering projects. It has many advantages, such as cost savings and environmental efficiency, but there are some important drawbacks to consider. It is important to weigh the pros and cons of this method carefully when deciding which excavation method is best for your project.
