Hydraulic anchor drill truck: The prospects of coal mine anchor drill RIGS in China
There are over 3,000 tunneling faces in state-owned coal mines alone every year. The construction of anchor bolt support requires a considerable number of anchor bolt drilling machines. The market demand has led many research and manufacturing units to invest in the development and production of anchor bolt drilling machines and their supporting equipment. There are various product types, and similar products keep emerging and being repeatedly tested. The anchor drill rig is an objective need for the development of anchor support technology. It is bound to move forward according to certain laws. After a period of competition, it will gradually get on the right track. After analyzing domestic and foreign anchor drill RIGS, it is believed that the development trend of coal mine anchor drill RIGS will have the following characteristics: (1) As coal mine anchor support will be widely applied in large quantities of coal roadways and semi-coal rock roadways, for a considerable period of time, single anchor drill RIGS will be the mainstream of anchor drill rig product development. In some roadways where integrated tunnel boring machines are used, hydraulic single-unit anchor drilling RIGS will gradually be adopted, and the hydraulic power source of the tunnel boring machines will be shared. To further enhance the mechanization level of anchor bolt support for comprehensive excavation equipment, we will continue to explore how to widely utilize airborne anchor bolt drills. Airborne anchor drill RIGS still mainly use hydraulic rotary drilling methods, but they will still seek reasonable drilling methods to solve the problem of drilling rocks with high compressive strength and strong abrasiveness. In large-section rock tunnel excavation, the use of hydraulic drilling vehicles will further demonstrate their superiority in drilling anchor bolt holes and installing anchor bolts, while the application of dedicated anchor bolt drilling vehicles will not be put on the agenda in the short term. (2) Hydraulic rotary anchor drill RIGS will develop in the direction of further increasing output torque to meet the needs of high-speed drilling of anchor holes and installation of anchor rods. The hydraulic anchor drill rig will not only further improve its technical performance but also enhance its reliability, with a focus on addressing the durability of hydraulic components and the long-term stability of underground operation. It will also seek ways to share power sources with existing underground equipment. To broaden the application scope of hydraulic anchor bolt hole drilling, people will explore the issue of high-torque rotation combined with low-energy impact anchor bolt hole drilling. (3) The pneumatic anchor drill rig has good torque-speed characteristics, is lightweight and has a large stall torque. However, the reliability of the product and the stability of product quality will attract more attention for a period of time. In order to use pneumatic anchor drill RIGS more widely, coal mine sites will consciously adjust the compressed air system and gradually pay attention to the application of mobile air compressors underground. (4) Electric anchor drill RIGS have low costs, simple main engine power and low energy consumption. People will continue to make efforts to improve the reliability of electric anchor drill RIGS and reasonably solve the problem of outrigger methods. Given the problems of hard torque characteristics and poor motor reliability of electric anchor drill RIGS, when using pressure water to flush anchor holes, the key to motor reliability will lie in overload capacity and waterproof and sealing performance. Only after the two issues are fundamentally resolved can electric anchor drill RIGS be more widely used in underground operations. (5) The pneumatic impact type anchor bolt hole drill is used in conjunction with the pneumatic rotary anchor bolt drill and the pneumatic rotary drill (side anchor bolt hole drill), making the underground power system single and achieving good results. People will further improve the pneumatic impact rock drilling method to better match the pneumatic rotary drilling method. (6) The drilling tools used in rotary drilling for anchor bolt holes are consumable and vulnerable parts with large consumption. With the normalization of anchor drill rig products, the performance and quality of drilling tools will be given more attention. The structure, materials and processing techniques of drilling tools will gradually become more reasonable, and the application range of rotary drilling methods will be expanded. (7) The further development of anchor drill RIGS requires a further improvement in the standardization level of anchor drill RIGS and their supporting equipment. In this technology, product competition will mainly lie in quality, service and price. For this reason, some manufacturers of anchor drill RIGS and drilling tools will make efforts in scientific management and gradually and consciously implement the ISO 9000 series standards to make their products more competitive. (8) The research on the performance parameters of anchor drill RIGS is the foundation for the product development and quality control of anchor drill RIGS. The competition among several products will gradually enhance the recognition of the importance of fundamental research on anchor drill RIGS. In the competition of anchor drill rig products, manufacturers will compete for technology, talent and the construction of conditions. (9) The development of anchor drill RIGS has certain technical difficulties, and its application effect is related to the on-site usage and maintenance conditions. The coal mine site will seek to apply scientific management methods for anchor drill RIGS, attach importance to and strengthen the maintenance and upkeep of anchor drill RIGS, and establish maintenance points for anchor drill RIGS. (10) The level and quality of anchor drill RIGS affect the comprehensive benefits of anchor support. On-site coal mines will gradually pay attention to the comprehensive economic benefits of using anchor drill RIGS and drilling tools, and take it as an important basis for choosing anchor drill RIGS and drilling tools.
