development history (Down-The-Hole Bit) is a drill bit commonly used in underground drilling. Due to its high efficiency, stability and reliability, it is widely used in mines, geological exploration, infrastructure construction and other fields. Its development history is as follows:
In the 1960s, the Swedish Epiroc (formerly Atlas Copco) company developed the DTH drill bit, which adopted a new drill bit design and impactor structure to improve drilling efficiency and reliability.
In the 1970s, DTH drill bits were widely used in Sweden, Australia and other countries, and achieved remarkable results in projects such as mines, tunnel engineering, and hydropower stations.
In the 1980s, DTH drill bits developed rapidly in the North American market, especially in the field of oil and gas development, and became an important drilling tool.
In the 1990s, DTH drill bits have been widely used around the world, and the technology has been continuously updated and improved, which has improved drilling efficiency and reliability, making it an indispensable tool in mine and engineering construction.
Since the 21st century, with the continuous expansion of the scale of mines and engineering construction, the application of DTH drill bits has become more and more extensive. The application of new materials, new technologies, and new processes has continuously promoted the development of DTH drill bits, making them play a greater role in fields such as mines, geological exploration, and infrastructure construction.
