AT-3000 frame wheel-rail type raise drilling rig AT-3000 frame wheel-rail type raise drilling rig is a high-end raise construction equipment for ultra-deep, large-diameter and complex geology. It integrates high-strength frame structure and intelligent wheel-rail mobile system, and has both the stability of heavy equipment and the flexibility of modular deployment. It is suitable for deep mines, ultra-deep vertical shafts of water conservancy and difficult underground projects.
LOOKING AT-3000 frame wheel-rail raise boring machine adopts a wheel-rail mobile frame, which can adapt well to various narrow spaces underground. Even if your tunnel slope is large, it can be flexibly deployed. In addition, it has a modular structure, which is convenient for you to disassemble and transport it, suitable for deep wells or remote mining projects.
AT-3000 adopts a fully enclosed operating room equipped with a safety monitoring system, which can maximize the safety of your operators. In addition, our hydraulic system is also designed with multiple protections to avoid accident risks such as drill jamming and overload during construction, ensuring your construction safety.
Our AT-3000 raise boring machine adopts high torque and high thrust design, which significantly improves the drilling speed under hard rock conditions and can effectively shorten your construction period. In addition, the use of automatic rod changing technology reduces manual intervention and has strong continuous operation capability, which can greatly save your construction costs.
The difficulties in using raise boring machine for ultra-deep hole operations mainly include the deflection caused by the deadweight of the drill pipe, the decrease in slag removal efficiency, and the increased wear of the roller cutter. It is recommended to use lightweight drill pipes, high-pressure gas lift and mud dual-mode slag removal, and high-hardness roller cutters.
The climbing angle of AT-3000 raise boring machine is 15 degrees.
