What is DTH drilling? DTH drilling is an efficient drilling technology that uses compressed air as a power source to break rocks through the impact of a DTH hammer. It is suitable for projects such as mining and tunneling. This article will introduce DTH drilling in detail from the aspects of the concept, origin, key components, principles, application fields, and advantages.

This article focuses on the key design principles of several core components of the DTH drill bit. It details the design concepts behind the carbide surface, water holes, impact end face, splines, and water grooves. By exploring these critical elements, readers can gain insights into how each component contributes to the drill bit’s performance, durability, and adaptability in various rock drilling applications.

This article outlines key operating specs for DTH drilling tools, including lubrication, unobstructed air passages, forward rotation, and water volume control, to aid maintenance, extend tool life, and ensure safe, efficient drilling.

DTH hammers are widely used in fields such as mining and water conservancy projects due to their advantages of high-speed drilling, low energy consumption, high-quality hole formation, large-diameter hole drilling, and easy operation. This article provides a detailed explanation of their core application advantages.

This article introduces DTH drill bits in detail from the perspectives of definition, structural design, classification, working principle, material selection, core advantages, and application scenarios.

In recent years, button bits have developed rapidly in geotechnical engineering fields at home and abroad, becoming widely used drilling tools. Compared with other rock drill bits, they have significant advantages such as high efficiency, durability, and strong adaptability. Many technical engineers believe that the combination of button bits and hydraulic rock drilling rigs can be regarded as the core support for current rock drilling technology. So, what is a button bit? What are its core advantages? How are the product categories divided? How do we make a scientific selection in engineering practice? Today, we will share all this with you.

The drill rod is an indispensable tool in drilling operations such as exploration, mining, and tunnel excavation. It serves as a crucial medium for transmitting the rotational power and axial pressure of the drilling rig to the drill bit, ensuring that the drill bit can continuously and stably break rocks or other materials and extend the borehole. If the drill rod performs poorly or malfunctions, it will directly affect the drilling efficiency, slow down the drilling progress, and increase construction costs. For example, insufficient wear-resistance of the drill rod will cause premature wear of the rod body. Frequent replacement of the drill rod not only wastes time but also raises material costs. Therefore, proper transportation, storage, and use of drill rods are of vital importance. Only by ensuring the correct transportation, storage, and use of drill rods can the safety of drilling operations be guaranteed, work efficiency be improved, and the service life of drill rods be extended. To extend the service life of drill rods, this article will provide a detailed introduction to the three key aspects of drill rod transportation, storage, and use, offering a reference for everyone.

Rock drill bits are one of the most important tools used for rock drilling and are widely used in many fields, such as mining, tunnel penetration, and municipal facilities. There are many types, and different scenarios require different specifications of rock drill bits. Among them, the diameter of the rock drill bit is directly related to the efficiency and quality of rock drilling. Therefore, when selecting a rock drill bit, it is necessary to reasonably determine its diameter to ensure rock drilling speed and mining cost. In rock drilling engineering construction, the correct selection of the size of rock drill bits is a core factor determining the project outcome. This crucial parameter not only directly affects the penetration rate and torque requirements during the rock drilling process, but also is closely related to the quality, and stability of the boreholes and the service life of the drilling tools. Ultimately, it determines the construction quality in different scenarios such as blast holes, anchoring projects, and core sampling. To determine the diameter appropriately, it is necessary to consider the factors that influence rock drill bits.

In the process of human development and infrastructure expansion, drilling through rocks has become an essential activity. Whether in mining operations for extracting mineral resources or in the construction of energy and transportation infrastructure such as railways, highways, water conservancy, and hydropower projects, rock drilling plays a crucial role. The effectiveness of rock drilling directly impacts the speed, quality, safety, and cost of subsequent engineering activities.
