CITIC Heavy Machinery Co., Ltd. has recently achieved a major breakthrough in the field of large-scale mining equipment, successfully developing and producing the world's largest shaft drilling rig with full independent intellectual property rights. This groundbreaking machine features a drilling diameter of 13 meters, a depth capacity of 1,000 meters, and a maximum lifting capacity of 700 tons. The achievement marks a new milestone for CITIC Heavy Machinery, showcasing its world-class research and development capabilities in the production of large-scale drilling rigs.
The working principle of this massive shaft drilling rig is similar to that of an oil drilling rig, but it is significantly more complex in terms of technical content and structural design. It integrates advanced technologies in mechanical engineering, electrical systems, hydraulics, and mud circulation. Currently, only a few countries—such as the United States, Japan, Germany, and China—possess the core technology required to manufacture such large-scale drilling rigs. CITIC Heavy Machinery stands out as the sole Chinese manufacturer capable of designing and producing large-diameter shaft drilling rigs, making it a key player in the global mining industry.
The introduction of these large-scale drilling rigs has revolutionized the construction of large coal mines, especially in unstable geological formations. According to feedback from users, the shaft drilling rigs developed by CITIC Heavy Machinery have made a "special contribution" to the Chinese coal industry, enhancing efficiency and safety in deep mining operations.
Leveraging the expertise of its state-level enterprise technology center, CITIC Heavy Machinery has continuously improved the design and manufacturing of large-scale drilling rigs in recent years. To date, the company has produced six large drilling rigs with diameters exceeding 9 meters. These machines have been deployed across major coal mines nationwide, successfully drilling over 30 large-diameter shafts. With ongoing innovation and technological advancement, CITIC Heavy Machinery continues to lead the way in the global mining equipment market.
