Product Description:
Our raise borer KDTJ-4000L is designed by our company in response to the new characteristics of underground mining technology. This model optimizes the original rock drilling parameters and uses system integration technology to reduce the overall size of the machine. The walking part adopts a track integrated walking, which can better adapt to the tunnel environment.
Features:
1) Fully automatic unloading rod, eliminating manpower and improving construction efficiency.
2) The automatic anti deviation control system for guide holes can eliminate drilling deviation caused by rock structure and poor manual operation.
3) Remote control and line control dual-use operation, simple operation, programmatic control with minimal human intervention, easy to learn, and can be operated by general personnel in a short period of training.
4) Crawler self-propelled walking, easy to move.
5) High work efficiency, high parameter indicators, large surplus torque and tension, suitable for construction with a diameter of 4.5 meters.
6) Electrical and hydraulic components are made of fully imported components, ensuring high reliability. The hydraulic system adopts the German Linde hydraulic closed hydraulic system, which has high hydraulic transmission efficiency and low reactive power.
7) 4.0m can be selected on the controller 3.5m There are four types of drilling machines, 3.0m and 2.5m, for aperture matching operations. Different gear ranges can be selected for drilling machines to meet the needs of different apertures.
8) Module integrated assembly, easy maintenance and repair, and the small size of the whole machine can adapt to smaller tunnel conditions.

Applications:
Mining: Our raise boring machines are mainly used for the following purposes:
Install anchor rods and wire rope nets to enhance the stability of the mine.
Establish a mine ventilation system to ensure the safety of miners during their operations.
Eliminate accumulated water in the mine to prevent mine flooding.
Transport ore to improve the efficiency of ore transportation.
