Major Breakthrough! China's First Dual-System (Gyro + Fluxgate) Trajectory Surveying Device for Mining – ER-GyroTracker-21 – Officially Released!
This innovative device, embodying the strength of domestic technology, features a probe diameter of only 24.75mm, making it not only the smallest in its class but also achieving an ultimate balance between performance and cost. Its overall cost is only 1.5 times that of a single-system product, providing dual measurement assurance at a highly competitive price.
The core system of the ER-GyroTracker-21 consists of the probe and a mining-enabled smartphone, enabling fully intelligent processing from data acquisition and transmission to analysis and presentation.
Dual-system integration: Synergistic innovation of gyro and fluxgate
The core technological breakthrough of the ER-GyroTracker-21 lies in its innovative "gyro + fluxgate" dual-system design, achieving functional complementarity and backup, greatly improving the equipment's adaptability and reliability under complex working conditions.
Three model are available: Model A features a dual system of gyroscope and fluxgate, Model B is a pure gyroscope system, and Model C is a pure fluxgate system. Users can choose flexibly according to their actual needs and budget.
True North and Magneto North Dual-Mode Output: The equipment can intelligently select or manually switch the output mode according to the actual downhole conditions. In areas with stable magnetic fields, the fluxgate system provides an efficient and economical measurement solution; once strong magnetic interference is encountered, the system can seamlessly switch to gyroscope mode, eliminating the need for drilling and significantly saving operation time and costs.
Dual systems provide mutual backup and reference: In high-precision measurement tasks, the two systems can work synchronously, with data mutually correcting each other, effectively reducing errors in a single system and improving overall measurement accuracy, providing dual protection for measurement tasks under extreme conditions.
MEMS strapdown inertial navigation system: Eliminating the influence of magnetic fields at the hardware level, it can still ensure the stability and accuracy of trajectory measurement even in extreme environments with complex geological structures and chaotic magnetic fields underground.
Measurement while drilling: process controllable, results reliable
The ER-GyroTracker-21 uses an ultra-fine probe with a diameter of only 24.75mm, which can be directly installed inside the drill pipe and advanced with the drill, achieving true "MWD" without any manual intervention, thus eliminating the problems of false drilling and empty drilling from the source.
Synchronous Track and Depth Acquisition: The probe integrates high-precision angle and depth sensors, simultaneously acquiring azimuth, inclination, and depth data during drilling to construct a real-time three-dimensional borehole trajectory. Azimuth measurement accuracy reaches 1°, inclination measurement accuracy reaches ±0.1°, and depth measurement accuracy does not exceed 1 meter, meeting various high-precision exploration requirements.
Strong Anti-interference Capability: The gyro mode is completely unaffected by magnetic field environments, ensuring stable and accurate operation even under complex electromagnetic conditions downhole. The probe has a pressure resistance of no less than 12MPa, enabling long-term reliable operation in harsh downhole environments.
Flexible adaptation and wide applicability
The ER-GyroTracker-21 is designed with the diversity and complexity of field applications in mind, offering excellent environmental adaptability and operational flexibility.
Multi-size drill pipe compatibility: The probe can be used with drill pipes of various diameters, including Φ30mm,Φ42mm, Φ50mm, Φ63.5mm, and Φ73mm, providing strong applicability.
Dual propulsion detection modes: Real-time measurement while drilling captures dynamic changes in the borehole trajectory, and handheld retesting via the push rod meets post-drilling verification and inspection needs.
Dual communication guarantees: It defaults to Bluetooth wireless transmission, eliminating cable constraints; a wired communication interface is also retained to ensure stable and reliable data transmission in areas with complex signal conditions.
Full-scene coverage, facilitating precise exploration
The ER-GyroTracker-21 is widely used for:
Precise measurement of drilling trajectories for various types of boreholes in coal mines;
Real-time monitoring and control of azimuth during directional drilling and straight-line drilling;
On-site verification and quality assessment of drilling accuracy in directional drilling sections;
Precise measurement of the depth of various engineering and exploration boreholes.
The release of the ER-GyroTracker-21 dual-system trajectory surveying device for mining represents a significant technological innovation in the field of mining surveying equipment. The widespread adoption of this equipment will powerfully drive the transformation of drilling operations from "experience-driven" to "data-driven," enabling visualization, controllability, and optimization of the drilling process. It offers significant engineering value and economic benefits in reducing ineffective drilling, saving construction costs, preventing drilling accidents, and improving the accuracy of resource exploration.
