Product Introduction
The DJ Series Drill Jumbo is a tunnel and mine rock drilling equipment developed by China Railway Engineering Equipment Group Co., Ltd. (CREG) for drill and blast excavation construction. Its maximum coverage area ranges from 28㎡ to 210㎡ (depending on the model), the maximum drilling height is from 5.1m to 14m (depending on the model), and the drilling diameter ranges from 43mm to 140mm. It is mainly used for drill and blast excavation operations in tunnels, mines, water conservancy, municipal engineering and other scenarios, and can also be used for a variety of operations such as advanced geological drilling, advanced pipe shed drilling, advanced grouting drilling, radial anchor rod drilling, auxiliary charging and scaling.
KEY FEATURES
1. Automatic Hole Pattern Design: Supports hole pattern design, tunnel line and contour line design (matching the core function of CREG ICS 4.0 intelligent drilling system in the official PDF)
2. Total Station Navigation: Enables rapid and accurate jumbo positioning (consistent with the official PDF's "Total station navigation set" configuration)
3. Multi-mode Hole Depth Reference: Supports flush bottom, equal hole length, and design hole pattern-based depth setting
4. Tunnel 3D Scanning: Realizes tunnel feature recognition and over/under-excavation analysis (matching the official PDF's 3D scanning system configuration)
5. Manual / One-click / Automatic Drilling: Realizes precise control, with anti-jamming and anti-blanking functions for efficient drilling (consistent with the official PDF's advanced drilling control system)
6. Boom Anti-collision Function: Provides collision warning between the boom and the car body itself, as well as the rock wall
7. Safety Protection: Equipped with anti-intrusion protection to ensure operation safety (matching the official PDF's FOPS/ROPS safety cabin standard)
8. Data Collection and Transmission: Real-time recording and remote transmission to the management and control platform (consistent with the official PDF's data transfer and MWD system)
9. Fault Diagnosis: Real-time monitoring and auxiliary fault troubleshooting (matching the official PDF's intelligent system fault diagnosis function)
10. It is applicable to full-face and short bench construction methods for various tunnels with a cross-sectional area of 50-190㎡, with strong adaptability to surrounding rock and geological conditions.
11. It can realize full-face excavation and one-time forming of the overall cross-section under Class II surrounding rock conditions; under Class V surrounding rock conditions, it can perform micro-bench excavation after one-time positioning, reducing excavation procedures.
12. The intelligent three-boom drill jumbo is equipped with intelligent functions including automatic hole pattern design, one-click automatic drilling and advanced geological prediction.
13. The equipment delivers fast drilling speed, advanced and reliable intelligent functions, reduces drilling tool consumption by more than 30%, with flush bottom accuracy ≤10cm and hole positioning accuracy ≤7cm — all reaching the international advanced level.
