The development history of rock drilling tools for hydraulic rock drill jumbos

Hydraulic rock drill jumbos appeared in the 1970s. At that time, due to the compressibility of air and limitation of volume of rock drilling machines, efficiency of pneumatic rock drilling machines powered by compressed air was greatly limited, and the rapid development of industry constantly put forward new requirements for the performance of rock drilling machines. In this case, a new type of rock drilling machine powered by hydraulic oil began to appear on the market. Superior performance of hydraulic rock drill jumbo was soon recognized by engineering department, and the market demand and production quantity increased with years. However, high impact power, large rotary torque, and high impact frequency of hydraulic rock drill jumbos make original rock drilling tools used in the independent rotary pneumatic rock drill can not complete the work of fast drilling, and the unique form of stress wave power transmission of hydraulic rock drill jumbo also puts forward new requirements for traditional structure of rock drilling tools.

In the early 1980s, research and development of rock drilling tools for hydraulic rock drill jumbos has become one of the main tasks of various enterprises. Among them, Sandvik of Sweden, Krupp Widia of the former Federal Republic of Germany, Kometa OY and Robit Rock Tools of Finland, Ingersoll–Rand of the United States, Padley & Vcnables of the United Kingdom, Rocbo GMBH of Austria. Japan’s rock drilling tools manufacturers have made contributions to the research and development of rock drilling tools for hydraulic rock drill jumbos, which have greatly improved product performance, such as Mitsubishi Metal Mining Co., LTD., Datong Steel Co., LTD., Toshiba Rock Drilling Tools Co., LTD., Toyo Rock Drilling Tools Co., LTD., Koha Rock Drilling Machinery Co., LTD. It can be said that decade from the mid-1980s to the mid-1990s was the period of the fastest development of rock drilling tools for hydraulic rock drill jumbos.

After entering the 21st century, with the change in market economic situation, international rock drilling tools manufacturing enterprises began to develop into a large group model. Large manufacturing enterprises such as Sandvik in Sweden, Atlas Copco, and Boart Longyear in the United States have acquired many small and medium-sized enterprises of rock drilling machinery and rock drilling tools in the world, which enterprises have formed a comprehensive production of rock drilling machinery, cemented carbide, brazing steel, and rock drilling tools. On the other hand, with the technological progress of machinery industry, the performance of hydraulic rock drill jumbos is also constantly improving, the progress of rock drill machinery to the direction of high performance is very fast, and the use requirements of rock drilling tools are getting higher and higher. At present, Sandvik and Atlas Copco have become major international manufacturers of rock drilling machinery and rock drilling tools. In the early years of this century, these two companies took advantage of the characteristics of their production of hydraulic drill jumbos and combined them with the development of the performance of hydraulic drill jumbos. They carried out a lot of research and development work in the product structure of rock drilling tools for hydraulic rock drill jumbos. And finally, a series of new products had been successfully launched.

Currently, the market demand and development trend for rock drilling tools for hydraulic rock drill jumbos is escalating annually. As the pace of engineering construction accelerates, the need for efficient, safe, and environmentally-conscious rock drilling equipment is also escalating. Nevertheless, the existing range of rock drilling tools for hydraulic rock drill jumbos continues to exhibit limitations, such as subpar drilling efficiency, relatively brief operational life, and substantial maintenance expenses. Therefore, the future trajectory and direction for development lie in enhancing the performance and quality of rock drilling tools for hydraulic rock drill jumbos to fulfill the burgeoning market demands and boost competitiveness.
