    Opis:
    Recently remarkable advancement development of unmanned aerial vehicles (UAVs) has been observed and their applications have been shown in many fields such as agriculture, industry, and environmental management. However, in the mining industry, the application of UAV technology remains potential. This paper presents a low-cost unmanned aerial vehicle technology-based system for 3D mapping and air quality monitoring at open-pit mine sites in Vietnam. The system includes several dust sensors that are mounted on a low-cost rotary-wing type UAV. The system collects a variety of data, mainly images and airborne pollutant concentrations. To evaluate the performance of the proposed system, field tests were carried out at the Coc Sau coal mine. Based on the images transmitted to the ground monitoring station, large scale 3D topographic maps were successfully modeled. In addition, sensors mounted on the UAV system were able to monitor the levels of environmental variables associated with the air quality within the pit such as temperature, dust, CO, CO2, and NOx. The field test results in this study illustrate the applicability of the low-cost UAV for the 3D mapping and the air quality monitoring at large and deep coal pits with relatively high accuracy.

    Opis:
    Vietnam is a country with abundant mineral resources, in recent years, the minerals mining (MM) has affirmed its very important position in contributing to the development of the national products, alleviate Vietnam's economy to a higher level at a rapid pace in recent years. However, the MM in recent years has caused many negative impacts on long-term economic and social development, posing unpredictable consequences on the environment... This leads to the need to strengthen the Government’s management work. In the effort to manage mining extraction, this is considered a complex field that has not been uniformly understood, and there remains several inadequacies and insufficient support in the process of performing management procedure. Therefore, although the Government requires to tighten the management of mineral exploitation, the effectiveness and efficiency are not reached, and many mistakes occur in the process of the procedure. Given the mentioned challenges of the management of control and the audit results of the State Audit on internal audit in recent years, there are a number of important tasks that need to be focused on auditing, including (i) Audit of mining license; (ii) Audit of mined reserves and output; (iii) Audit of environmental safety protection and inspection of mining activities.
