In the previous chapters, the electric shovels in open-pit mines, tunneling machines in coal mines, and coal mining machines were introduced. This chapter will sort out the brands of commonly used rock drilling jumbos in mines.

Non coal mining mainly adopts the most economical and effective drilling and blasting method, and rock drilling equipment is an important equipment for drilling and blasting method. From the development process, it has mainly gone through processes such as handheld pneumatic rock drills, fully hydraulic rock drilling trolleys, electro-hydraulic control consoles, and fully computerized trolleys.

Prior to 2000, most of the more advanced drilling equipment was imported from abroad, and the main brands were Atlas Copco, Sandvik, etc. After nearly 20 years of rapid development, the gap between China's rock drilling equipment and foreign brands has become smaller and smaller. At the same time, due to its high cost-effectiveness, with the help of China's rapid development in the past 20 years, it has been greatly improved and surpassed in practice.

The introduction of foreign brands is available on many websites, and will not be elaborated in this chapter. This article will sort out the domestic brands that have done well. Representative production enterprises in China include Jiangxi Xintong Machinery Manufacturing Co., Ltd., Zhejiang Zhigao Machinery Co., Ltd., China Railway Construction Heavy Industry Group Co., Ltd. (referred to as "Railway Construction Heavy Industry"), Xugong Group Engineering Machinery Co., Ltd. (referred to as "Xugong Group"), etc.

The earliest rock drilling equipment was mostly handheld and cannot be replaced in many scenarios. Currently, commonly used pure hydraulic and electro-hydraulic rock drilling equipment is facing opportunities for upgrading and transformation. Fully computerized intelligent trolleys will gradually become a competitive trend for rock drilling equipment. Currently, many enterprises are investing heavily in intelligence and environmental protection.

The intelligent three-arm rock drilling rig developed by Jiangxi Xintong is based on the positioning technology of tunnel construction equipment, 3D reconstruction technology of tunnel contour, and intelligent control technology of rock drilling machines. It integrates functions such as fully automatic drilling, anchor rod construction, excavation surface contour scanning, shotcrete thickness detection, remote communication and data interaction, advanced geological exploration and analysis, and fully automatic slag removal system, solving the problems of digital borehole design, bulky and difficult positioning of drilling arms The problem of difficulty in high-precision positioning in tunnel engineering greatly reduces the intensity of drilling operations, improves construction efficiency, and reduces the phenomenon of over and under excavation, which can meet the requirements of large and medium-sized section rock drilling construction and mining and coal mine rock roadway excavation.

Zhejiang Zhigao's rock drilling rig also performs well in terms of environmental applicability, and is widely used in underground mining, tunnel excavation, blasting, drilling, anchor bolt holes, and other mechanized projects.

The first fully computerized three arm rock drilling jumbo developed by China Railway Construction Heavy Industry was launched in 2016. By controlling over and under excavation, material costs were saved by more than 50%; The shaping effect of tunnel cross-section contour is good; Equipped with a complete geological analysis system and safety alarm system, not only real-time monitoring and recording of drilling process information, but also automatic analysis of geological conditions.

XCMG Group's research and development of rock drilling rigs started relatively late, but after nearly a decade of rapid development, the product line is relatively comprehensive and there are also many application scenarios. For example, with industry-leading adaptability to working conditions and drilling positioning accuracy, and equipped with the world's first deep vision remote control operation system, the XTZ3200 three-arm rock drilling jumbo easily achieves real-time sharing of vehicle information and remote control operation, ensuring the safety of tunnel excavation.

Although automation and large-scale machinery have gradually been put into operation in tunnel and mine mining, there is still a need for experienced teachers to refine the excavation process in tunnel and shaft mining with special geological conditions.

BUTTRESS ROOTS will provide the latest brand collection and supply to global mining users.
