Zhejiang Kaishan Co., Ltd. is currently the largest manufacturer of pneumatic rock drills in the world. It is the enterprise with the highest market share of rock drilling and mining equipment such as down-the-hole machine, down-the-hole drilling rigs, and pneumatic tools. China University of Geosciences (Wuhan) is an educational It is a national key university directly under the Ministry of Foreign Affairs. It is a university of the national “211 Project” and “985 Advantageous Discipline Innovation Platform” construction projects. It has two national first-level key disciplines of geology, geological resources and geological engineering. Has a wealth of technical achievements and experience.
On June 24 this year, China University of Geosciences (Wuhan) established a board of directors, and Kaishan Group became the director unit of the first board of directors. A bridge of friendly cooperation and common development. A few days ago, with the strong support of President Wang Yanxin of China University of Geosciences, Zhejiang Kaishan Co., Ltd. successfully acquired 51% of the shares of Wuhan Dihaizhuo Drilling Technology Co., Ltd., a subsidiary of China University of Geosciences (Wuhan), thus becoming the owner of The largest shareholder and holding company of Wuhan Dihaizhuo Drilling Technology Co., Ltd., which produces a series of products such as full hydraulic road drilling rigs, mining rigs, surface rock drilling rigs and hydraulic rock drills. In order to deepen mining technology research and accelerate advanced rock drilling equipment A good foundation has been laid for development.
Since Montabet of France successfully developed the world’s first hydraulic rock drill in 1970, Secoma of France and Ingersoll Rand of the United States, Atlas of Sweden and Tom Rock of Finland, Furukawa of Japan and Japan’s Toyo Corporation also developed hydraulic rock drills successively in 1970, 1973, and 1977, which led to the development of fully hydraulic rock drilling rigs and created a new era of fully hydraulic rock drilling equipment. More than 40 years of practice have shown that: 1) Fully hydraulic rock drilling equipment uses high-pressure oil as power, and the energy utilization rate is high, reaching more than 50%, and the energy consumption is only 1/2-1/4 of similar pneumatic rock drills; 2 ) has a higher rock drilling efficiency, generally 1-1.7m/mim, while the pneumatic rock drill is only 0.2-0.5m/mim; 3) The working environment has been greatly improved, and the rock drilling noise is 10%-15% lower. Dust, oil mist, good visibility, 4) can realize automatic operation, light labor intensity; 5) good drilling effect, can adjust the impact energy according to the rock conditions, can not only reduce the jamming, but also ensure the best rock drilling speed. Therefore, fully hydraulic rock drilling equipment is widely used in mining, roadway excavation and engineering construction in Europe, America, Australia, Russia, Japan, South Korea and other countries.
In September 1980, my country first appraised the fully hydraulic wheel-rail rock drilling rig designed by the former Central South Institute of Mining and Metallurgy and the hydraulic rock drill designed by the Changsha Research Institute of Mining and Metallurgy at the Xiangdong Tungsten Mine. Enterprises, research institutes, colleges and universities triggered an upsurge in the development of hydraulic rock drills, but they were disbanded one after another due to hydraulic design technology, hydraulic sealing technology, key parts materials, manufacturing equipment and process levels, and low technical levels of use and maintenance personnel. China University of Geosciences (Wuhan) Rock Drilling Machinery Research Institute Professor Li Yangeng and a few experts are persisting in research. Today, more than 30 years have passed, and the advantages of hydraulic rock drilling equipment, such as safety and speed, energy saving and environmental protection, and low labor intensity, have been recognized and accepted by the society. There are more and more imported hydraulic rock drills, and they are gradually replacing pneumatic rock drills and down-the-hole drilling rigs. and down-the-hole drilling rigs, indicating that the spring of the development of domestic hydraulic rock drilling equipment has arrived. However, due to the long delivery cycle, high price, untimely supply of spare parts and untimely service of imported equipment, many potential users are discouraged. At present, many domestic enterprises have also begun to produce hydraulic rock drilling equipment, but its core components—hydraulic rock drilling machines are basically imported, lacking core competitiveness. Therefore, there is an urgent need for domestic enterprises to undertake the development of full hydraulic rock drilling equipment as soon as possible.
As a professional manufacturer of rock drilling and mining equipment, Kaishan has a complete mechanical processing and manufacturing system, first-class mechanical processing equipment, heat treatment equipment and quality inspection facilities, a team of high-quality technicians and technicians, and fully equipped with full hydraulic drilling equipment. The processing, assembly and market service capabilities of rock equipment, while Wuhan Dihaizhuo Drilling Technology Co., Ltd. has long relied on the technical team led by Professor Li Yangeng from the Institute of Rock Drilling Machinery, China University of Geosciences (Wuhan), and has fully hydraulic drilling rigs and mining rigs. , surface rock drilling rigs and hydraulic rock drills and other products design and manufacturing technology. Therefore, after Zhejiang Kaishan Co., Ltd. took control, the two companies have joined forces and complemented each other’s advantages, fully equipped with the technology and conditions to develop full hydraulic rock drilling equipment. At present, the development of a series of products such as full hydraulic rock drilling rigs and hydraulic rock drilling machines is in full swing and will be put on the market in the near future. At the same time, with the technical strength of China University of Geosciences, we will continue to devote ourselves to the technical research of advanced rock drilling equipment such as coalbed methane drilling rigs, shale gas drilling rigs and ultra-deep water well drilling rigs, and vigorously develop efficient, clean, safe and unconventional energy mining and extraction equipment, we are willing to fully meet the needs of users with “the quality of imported products, popular prices and timely and thoughtful services”. Make due contributions to the low-carbon economy.
