Open-pit mining activities, including blasting, drilling, loading, and transport, often result in the direct emission of particulates and gases into the atmosphere. Occupational exposure to these pollutants is considered as the risk for health, especially the risk of developing respiratory diseases. An air quality monitoring system and spatial analysis are necessary to identify these potential hazards. In this study, we propose an air quality monitoring system that integrates gas and dust sensors into a small multi-rotor copter or unmanned aerial vehicle (UAV). Different spatial interpolation methods including trilinear interpolation, nearest neighbour, and natural neighbour applied to the monitoring data (CO, SO2, PM2.5, CO2) from our system to derive air concentration levels in the atmosphere of open-pit coal mines were also examined. The results show that the UAV based air quality monitoring system performed efficiently and safely in conditions of deep open-pit coal mines. In addition, for the estimation of the concentration level of gases and dust in unsampled points, trilinear interpolation performed with the most accurate result, followed by natural neighbor and nearest neighbor.

Wielorakie działalności ư górnictwie odkrywkowym, w tym roboty strzelnicze, wiertnicze, załadowania, transport, zwałowania itp. często prowadzi do bezpośredniej emisji pyłów i gazów do atmosfery. Zanieczyszczenie powietrza na terenie zakładu górniczego uważane jest za zagrożenie dla zdrowia pracowników i górników, zwłaszcza ryzyko rozwoju chorób układu oddechowego. Aby zidentyfikować te potencjalne zagrożenia, niezbędny jest system monitorowania jakości powietrza i analiza przestrzenna. W artykule, przedstawiono wyniki zastosowania system monitorowania jakości powietrza, który integruje czujniki gazu i pyłu w pospolitym wielowirnikowym helikopterze lub bezzałogowym statku powietrznym (BSP). Zbadano również różne metody interpolacji przestrzennej, w tym interpolację trójliniową, najbliższego sąsiada i naturalnego sąsiada, zastosowane do danych z monitoringu (CO, SO2, PM2.5, CO2) z badanego systemu w celu wyznaczenia poziomów stężenia powietrza w atmosferze kopalni odkrywkowych. Wyniki pokazują, że system monitorowania jakości powietrza oparty na BSP działał sprawnie i bezpiecznie w warunkach głębokich odkrywkowych kopalń węgla kamiennego. Dodatkowo, do oszacowania poziomu stężeń gazów i pyłów w niepróbkowanych punktach zastosowano interpolację trójliniową z najdokładniejszym wynikiem, a po kolei naturalny sąsiad i najbliższy sąsiad.
