Project Overview

A mineral exploration project in Xinjiang faced significant challenges in conducting conventional magnetic surveys across high-altitude mining areas.

The survey area was located at an elevation of approximately 1,200–1,890 meters, where conventional ground-based magnetic surveying required substantial time and resources.

To improve survey efficiency and support geological structure identification, the project introduced a drone aeromagnetic survey system.

The system established survey lines at 100-meter intervals and integrated ground-to-air electromagnetic detection technology to collect geological and geophysical data across the target area.

The drone-based survey completed data collection along a 19-kilometer survey line in 21 days, providing the exploration team with information for rapidly identifying potential ore-bearing structures and fault zones.

The resulting geological information helped define more precise targets for subsequent drilling and reduced the overall construction time by approximately 60%.

The Challenge

High-Altitude Mining Environment

The exploration area was located at an elevation of approximately 1,200–1,890 meters, creating additional operational challenges for conventional ground surveying.

Inefficient Conventional Magnetic Surveys

Traditional magnetic survey methods require survey teams and equipment to operate directly across the exploration area. This can increase field workload and extend the time required to collect sufficient geophysical data.

Large Survey Area

The project required magnetic data to be collected along a 19-kilometer survey line. Maintaining consistent survey coverage across a large exploration area can be time-consuming using conventional methods.

Geological Structure Identification

Identifying ore-bearing structures and fault zones is critical for mineral exploration. However, geological structures may not be directly visible from the surface and require reliable geophysical data for interpretation.

Need for Accurate Drilling Targets

Subsequent drilling represents a significant investment.

Exploration teams therefore need accurate geological targets to improve the efficiency of drilling programs and reduce unnecessary exploration work.

The Drone Aeromagnetic Solution

To address the limitations of conventional surveying, the project introduced a drone aeromagnetic survey system.

The system combines:

• Drone aeromagnetic surveying
• 100-meter survey line spacing
• Ground-to-air electromagnetic detection
• Geological structure analysis
• Drilling target identification

How the Drone Magnetic Survey Works

1. Plan Survey Lines

Survey lines are established at approximately 100-meter intervals according to the geological exploration requirements. This provides systematic coverage of the target exploration area.

2. Deploy the Drone Aeromagnetic System

The UAV system is deployed to conduct aerial magnetic measurements along the designated survey lines.

3. Collect Magnetic Data

The drone follows the planned routes while collecting magnetic field information across the survey area.

The aerial platform allows measurements to be acquired without requiring survey personnel to physically traverse every section of the terrain.

4. Integrate Electromagnetic Detection

Ground-to-air electromagnetic detection technology is integrated into the survey workflow to provide additional geophysical information. This helps the exploration team analyze subsurface geological characteristics from multiple data sources.

5. Identify Geological Structures

The collected geophysical data is processed and analyzed to identify potential ore-bearing structures and fault zones.

6. Define Drilling Targets

The interpreted geological information provides more precise targets for subsequent drilling and further mineral exploration.
