[0002] Mine geological stability assessment is an important part of mine security and is of great significance for preventing geological disasters, ensuring the safety of miners, and improving mining efficiency. The traditional method of mine geological stability assessment is generally to conduct manual measurements on the ground, collect geological data, and then conduct graphic analysis and expert evaluation. This method is labor-intensive, inefficient, and may cause errors due to human factors, affecting the accuracy of the assessment results.

[0003] In recent years, drones, as a new type of aerial measurement equipment, are gradually being widely used in many fields, including geological exploration, geographic information collection, environmental monitoring, etc. When flying in the air, drones can obtain a full range of views of the ground, and the sensor equipment they carry can collect data efficiently, making them very suitable for geological stability assessment.

[0004] However, the drones currently on the market mainly use cameras for visual observation and detection, and cannot directly provide the high-precision geological data required for geological stability assessment, such as surface elevation, geological cracks and other information. In addition, the pictures or video data taken by drones need to be manually analyzed and processed, which is inefficient and easily affected by human factors. There is a possibility of misunderstanding and misjudgment, and the time and labor costs are high. There are also doubts about whether they can provide accurate geological stability assessment results.

[0005] Therefore, the existing UAVs cannot fully meet the needs of mine geological stability assessment and need further improvement and optimization. The utility model is to solve this problem and proposes a multi-axis UAV laser measurement device that can provide high-precision geological data and has automatic analysis and processing capabilities.

The drone platform 1 includes a multi-axis aircraft structure, on which a laser scanning sensor 2 is installed. The laser scanning sensor 2 is electrically connected to a control module on the drone platform 1, and the control module controls the start, stop and scanning speed of the laser scanning sensor 2. The drone platform 1 is composed of a multi-axis aircraft structure and is provided with an installation position for the laser scanning sensor 2. It serves as a carrier to transport the laser scanning sensor 2 to the area where geological stability assessment is required.

The laser scanning sensor 2 is electrically connected through the control module on the UAV platform 1, and the control module controls its start, stop and scanning speed. Leica ScanStation series: This is a series of laser scanning sensors developed by Leica Geosystems, including models such as P50, P40, and P30. These devices have high-precision and long-distance scanning capabilities and are widely used in construction, civil engineering, mining and other fields.

[0026] The device also includes a data processing system 3, which wirelessly communicates with the laser scanning sensor 2 on the drone platform 1 and receives data collected by the sensor. The data processing system 3 includes a geographic information system GIS software for displaying the processed data in the form of geographic information.

[0029] The measuring device is also provided with a dustproof protective cover 6, which is installed outside the laser probe of the laser scanning sensor 2 to protect the laser probe.
