Seminar on the topic: Application of mineral materials and UAVs in the sustainable development of the mining industry.

At 2:00 PM on April 21, 2026, the IAST Institute will hold a seminar at its Hanoi Office – 13 Hang Bot Alley, O Cho Dua Ward, Hanoi City with the following details:

1/ Assoc. Prof. Dr. Bui Hoang Bac will present on the topic: Structural characteristics and properties of tubular haloysite nano-minerals from Thanh Son (Phu Tho) and some applications.
Abstract: This report systematically synthesizes and analyzes research results on the structural characteristics, properties, and application potential of tubular haloysite nano-minerals from the Thanh Son area, Phu Tho. Based on modern analytical methods (XRD, SEM/TEM, FT-IR, BET), the mineralogical characteristics and microstructure of the material are clarified, showing that haloysite mainly exists in the form of nano-sized tubes, with a 1:1 layered structure, large surface area, and significant ion exchange capacity.
Based on published experimental data, this study clarifies the relationship between the specific structure of Thanh Son haloysite and its application efficiency in two main areas: heavy metal treatment in water environments and the manufacture of fired ceramic materials. The novelty of this paper lies in proposing an integrated approach to clarify the "structure-property-function" relationship of domestic haloysite resources, which has not been fully systematized in previous studies in Vietnam. The research results provide a scientific basis for guiding material modification and enhancing the value of this mineral resource in industrial and environmental fields.

2/ Assoc. Prof. Dr. Nguyen Quoc Long presented on the topic: Some research and applications of UAVs in open-pit mining.

Abstract: This report presents several studies and applications of UAVs in Vietnam's open-pit mining sector:
1. Using UAVs to acquire high-resolution aerial imagery, build orthophoto maps, digital terrain models, and calculate rock and soil volumes. This clarifies the role of UAVs in improving the efficiency and accuracy of mine surveying.

2. Applying UAVs in monitoring mine slope safety, especially the ability to detect early signs of instability such as cracks, landslides, and deformation of the pit slope. UAVs allow for surveying hazardous areas that are difficult for humans to access, while creating 3D models to help assess safety visually and promptly.

3. Monitoring air pollution in mining areas through the integration of sensors to measure fine dust and industrial emissions. UAVs support the mapping of pollution distribution in space and time, contributing to improved environmental management efficiency during mining operations.
