However, in the mining industry, the application of UAV<br>technology remains potential. This paper presents a low-cost unmanned<br>aerial vehicle technology-based system for 3D mapping and air quality<br>monitoring at open-pit mine sites in Vietnam. The system includes several<br>dust sensors that are mounted on a low-cost rotary-wing type UAV. The<br>system collects a variety of data, mainly images and airborne pollutant<br>concentrations. To evaluate the performance of the proposed system, field<br>tests were carried out at the Coc Sau coal mine. Based on the images<br>transmitted to the ground monitoring station, large scale 3D topographic<br>maps were successfully modeled. In addition, sensors mounted on the<br>UAV system were able to monitor the levels of environmental variables<br>associated with the air quality within the pit such as temperature, dust, CO,<br>CO2, and NOx. The field test results in this study illustrate the applicability<br>of the low-cost UAV for the 3D mapping and the air quality monitoring at<br>large and deep coal pits with relatively high accuracy.</p&gt;}, number={2}, journal={Inżynieria Mineralna}, author={BUI , Xuan Nam and LEE , Changwoo and NGUYEN , Quoc Long and ADEEL , Ahmad and CAO , Xuan Cuong and NGUYEN , Viet Nghia and LE , Van Canh and NGUYEN , Hoang and LE , Qui Thao and DUONG , Thuy Huong and NGUYEN , Van Duc}, year={2022}, month={sty.} }
