The first high-pressure annular down-the-hole drilling rig in China was successfully tested underground.
China's first CS100ET high-pressure annular down-the-hole drilling rig has successfully completed its trial run at the Fankou Lead-Zinc Mine in Shaoguan, Guangdong. This marks a significant milestone in the development of domestic mining equipment, showcasing China's growing capabilities in advanced underground drilling technology.
According to reports from industry insiders, the CS100ET rig integrates the best features of similar foreign models while offering unique advantages such as high efficiency, energy savings, a high level of mechanization, and broad applicability. It is expected to be widely adopted across China’s mining sector in the coming years.
Developed by Hunan Nonferrous Heavy Machinery Co., Ltd., the CS100ET was specifically designed for the challenging conditions found in lead and zinc mines. The rig features a crawler-type self-propelled chassis that can operate using both diesel and electric power, allowing it to navigate complex underground environments with ease. Its 360-degree rotating drill arm makes it particularly well-suited for creating precise circular holes in underground mining operations. The entire system is controlled via a computerized interface, complete with safety features like malfunction protection and fault alarms.
During testing at the 120-meter-long working face in the Fankou mine, the rig demonstrated exceptional performance. It operated smoothly, achieved high drilling accuracy—ensuring reliable positioning and consistent results—and delivered impressive speed. In one test, the rig was able to perform 10 pneumatic drilling cycles within just 1.5 minutes, far exceeding expectations. Industry experts and on-site operators alike have given the machine high praise, highlighting its potential to revolutionize underground mining practices in China.
This successful trial not only demonstrates the technical prowess of Chinese manufacturers but also signals a shift toward more advanced, efficient, and environmentally friendly mining solutions. As the demand for mineral resources continues to grow, the CS100ET represents a key step forward in modernizing China’s mining industry.
