How can this north seeker empower mining?

In the process of modernizing mines towards intelligent and unmanned operations, what is visible is the roar and efficient operation of giant machinery; what is invisible is the underlying technological support that ensures the precise, safe, and orderly operation of all of this.

Traditional mines rely on human experience and external navigation signals, but in the process of transforming to intelligent operations, they face several fundamental technological bottlenecks:

Lack of satellite navigation signal: Underground tunnels and deep ore bodies completely block GPS signals.

Complex environment: The mining environment is full of vibration, dust, and electromagnetic interference, and its spatial structure is complex and variable, placing extremely high demands on the stability and reliability of orientation equipment.

Requirement for a unified reference in automated systems: When multiple unmanned devices operate collaboratively, a unified and accurate direction coordinate system is essential.

The core of these challenges lies in how to obtain a highly reliable, all-weather, absolute direction reference in underground spaces, independent of external signals. The ER-MNS-09 MEMS north seeker is developed based on this technology.

Technical Principles and Advantages

The essence of a north seeker is an inertial device capable of autonomously determining true north. MEMS north seeker represent the miniaturization and high reliability of this technology.

ER-MNS-09 Core Working Principle: Using a high-precision MEMS gyroscope, it senses the angular velocity vector of the Earth's rotation and calculates the true north direction precisely.

Accurate Measurement: The ER-MNS-09 provides azimuth and attitude references with an azimuth accuracy of 0.5° and an attitude accuracy of ≤0.2°, maintaining this accuracy for 20 minutes. The tilt measurement range is ±85°.

Autonomy: Completely autonomous north-finding, independent of any external signals, perfectly suited for enclosed underground environments.

Speed: Completes north-finding in 5 minutes, meeting the rapid response requirements of mobile devices.

Environmental Robustness: All-solid-state with no moving parts, shock and vibration resistant, long lifespan, and low maintenance costs, making it particularly suitable for harsh working conditions in mines.

The Role of the "Hidden Foundation": Precise Orientation Control of Mining Boreholes

The ER-MNS-09, by outputting the azimuth and attitude parameters of the drilling equipment, with an azimuth accuracy of 0.5°~1°, effectively controls borehole deviation, ensuring that the borehole reaches the target ore layer along the designed trajectory, improving resource recovery rate and exploration data accuracy.

Attitude Monitoring of Tunneling Equipment

During tunneling, the attitude stability of the equipment directly affects the accuracy of the tunneling direction and construction safety. The north-finding instrument provides the tunneling heading, and its attitude tracking function can capture changes in the pitch and roll angles of the tunneling machine, effectively suppressing tunneling deviation.

Positioning and Collaborative Operation of Mining Equipment

In multi-equipment collaborative mining scenarios, the ER-MNS-09 provides a unified azimuth reference for each piece of equipment, enabling precise collaboration between them.
