The development of down-the-hole drilling tools


The application fields of DTH drilling tools involve geological and mineral exploration, open-pit mining, construction excavation, water conservancy and hydropower engineering, mine quarrying for cement building materials, transportation engineering construction, rock anchoring engineering, underground metal mining, and urban water supply, municipal administration, and transportation, environmental and other construction projects.

Different from top hammer rock drilling tools, the core component of DTH drilling tool is DTH impactor. It has the characteristics such as deep drilling holes, large hole diameter, relatively high work efficiency and wide application range. Therefore, DTH drilling tool plays a very important role in drilling and blasting method rock drilling construction.

DTH drilling tool is a kind of high-efficiency rock drilling machine, which has strict quality requirements for the supporting impactor, DTH drill bit, drill rod, etc. According to the different compressed air pressures used in DTH drilling tools, they are usually divided into three types: low-pressure DTH tools (air pressure 0.6-0.8MPa), medium-high air-pressure DTH drilling tools (air pressure 1.0-2.0MPa), and high-pressure DTH drilling tools (air pressure greater than 2.5MPa).

In the past ten years, the R&D and production of middle and high pressure DTH drilling tools in China have made great progress. The DTH drilling tools market has spread all over the world. It has become one of the fastest-growing drilling tools after top hammer rock drilling tool. For companies, it is necessary to attach importance to product research and development. While further improving product performance and quality, they should also properly analyze the products and development trends of their counterparts. Therefore, it is necessary to further understand and master the development trend and product types of DTH drilling tools in the international market to promote its long-term effect.
