In the modern drilling technology, DTH hammers have been widely used across many fields due to their unique advantages. This article will provide a detailed introduction to the applications of DTH hammers to help you better understand their uses.

Features of DTH hammers

Efficient drilling speed

The DTH hammer achieves efficient drilling by combining high-frequency impact force with rotary force. Its drilling speed is significantly higher than the traditional rotary drilling methods, greatly enhancing drilling efficiency.

High reliability

The DTH hammer adopts advanced design and manufacturing technology and has high reliability. In harsh working environments, the DTH hammer can still maintain stable performance to ensure the smooth progress of drilling operations.

Wide adaptability

The DTH hammer can adapt to various complex formation conditions, including hard rock, broken formation, soft rock, etc. Its unique drilling method enables the DTH hammer to maintain an efficient drilling speed under complex formation conditions.

Environmental protection and energy saving

The DTH hammer generates less noise and vibration during the drilling process, reducing its impact on the surrounding environment. At the same time, its efficient drilling method also reduces energy consumption and costs.

Application areas of DTH hammers

Mining

DTH hammers are widely applicable to drilling and blasting, tunnel excavation, and other operations. Drilling with a DTH hammer can form regular holes, providing favorable conditions for blasting. At the same time, the DTH hammer has a fast drilling speed and can significantly improve tunnel excavation efficiency.

Geological exploration

Geological exploration is another important field of application of DTH hammers. In geological exploration, DTH hammers can drill and sample various strata, providing accurate and reliable data support for geological exploration. Whether in land or marine geological exploration, DTH hammers play an essential role.

Water conservancy engineering

DTH hammers are used for drilling in the construction of hydropower stations, reservoirs, and other projects. Their efficient drilling speed and high reliability significantly shorten the construction period and improve the quality of water conservancy projects.

Highway and railway construction

DTH hammers are used in tunnel excavation, bridge pile foundation construction, and other critical links. Its powerful drilling capacity and stable performance ensure the smooth progress of highway and railway construction.

Applicable objects of DTH hammer

DTH hammers are used for rock drilling, so it is necessary to understand the condition of the rock being drilled. According to the different causes of rocks, there are three major types of magmatic rocks, sedimentary rocks and metamorphic rocks. Throughout the long process of geological evolution, various types of rocks are often not in integrated condition, and there are soft and hard interlayers, internal tectonic defects, cracks, fractures, and so on. Due to the complexity and variability of various rock structures, rocks are not homogeneous or isotropic. Therefore, we should choose a suitable DTH hammer according to the type of rock.

Use of DTH hammer

Before using the DTH hammer, it is necessary to check the oil filler on the main machine to make it full of lubricating oil and ensure that there is still some left before the next start.

When the DTH hammer starts drilling, the operator should push it forward and hold the working surface by operating the control valve and opening the impact valve to activate the hammer. Be careful not to rotate the hammer at this time, as this could cause the drill bit to become unstable.

It is strictly forbidden to reverse the DTH hammer in the hole to prevent the impactor from falling into the hole.

When drilling downward or horizontal holes, do not stop the air supply to the DTH hammer at once when you stop drilling. The operator should lift the drill to carry out strong blowing and then stop the air supply when there is no more rock slag and rock powder discharged from the hole to prevent the rock slag from entering the inner part of the hammer and damaging the hammer after stopping the air supply.

Under normal rock drilling conditions, the hammer overhaul cleaning and reassembly, every 200 hours of work once, drilling water holes or slurry slag removal once every 100 hours. This work should be carried out as far as possible by specialized personnel in the repair shop.

Conclusion

With the advancement of technology and the growth of market demand, the application prospects of DTH hammers will be broader. In the future, we can expect DTH hammers to be applied in more fields and offer more efficient and reliable solutions for engineering construction.
