Tunnel drilling rig technology is developing towards intelligence, automation, and greening. Its core technologies mainly include intelligent positioning and control systems, remote and unmanned operation technology, dedicated software such as Dynamic Tunneling Kit (DTP), high-efficiency hydraulic control systems, and pure electric drive technology.
The intelligent positioning and control system can automatically import drawings, autonomously position equipment, and perform precise drilling. Positioning accuracy can reach centimeter level, and even improve to within 20mm . This system has functions such as automatic hole layout and one-click automatic drilling, completing a drilling operation in an average of 2 to 4 minutes.
Remote and unmanned operation technology, through the drilling rig control system (RCS) or intelligent control system, allows operators to remotely operate from the control room, achieving "one-click intelligent drilling" and unmanned underground operations, keeping personnel away from high-risk working faces.
The Dynamic Tunneling Kit (DTP) is a software function that allows the drilling rig to create customized drilling plans directly on the tunnel surface, improving the accuracy of tunnel excavation. High-efficiency hydraulic control systems, such as those allowing free switching between high and low pressure, can limit different maximum system pressures under varying operating conditions, achieving segmented control of high and low pressures and improving work efficiency.
Pure electric drive technology utilizes battery power, achieving zero emissions and zero pollution. It is suitable for special environments such as high-altitude areas, effectively solving the problem of competition for oxygen between equipment and personnel.
