Abstract
Mining, especially surface mining, has a significant impact on the upper part of the soil cover, including fauna and flora. The article deals with the use of geodetic methods to observe the mining process and its possible impact on the environment. The created model can be used to design the recovery and reclamation of open-pit mines after their closure and mining termination. For the modeling of an open-pit mine, 2151 points from two stages of geodetic measurements were used. Graphical presentations of the geodetic measurements were compared with data from aerial photogrammetry. The measurement and processing results were used to visualize the spatial changes in the open-pit mine, which are necessary to take measures related to the recovery of the landscape affected by mining. Based on the calculation, 145.266 m3 were extracted during the period under exploration. When calculating the average excavated volume per working day, it was found that 188 m3 = 500 tons = 0.5 kilotons per day were extracted between the monitored periods. When comparing the original surface and the generated model of the open-pit mine, it was found that the entire top of the rock massif was permanently removed in the total volume of 3,421,000 m3. To capture the impact of mining on the surrounding environment, multispectral images of Landsat 7 and 8 during the observed period. Focused attention was divided into two factors, land surface temperature, and vegetation condition. The results from the temperature maps show that the open-pit mine is becoming a heat island. Analysis of the vegetative state confirms the rapid change in the health of vegetation, resp. reduction of its condition in the area around the open-pit mine. The presented results show that the selected methods and procedures are applicable in the conditions of the small mining company in Slovakia.
Highlights
A country’s mineral wealth is considered to be an important economic factor and is linked to the economy of the country
In further fulfilment of the main idea of this study, several measuring and processing approaches were applied in the subject open-pit mine
The process of preparation, measurement, processing, and creation of the 3D model is illustrated as the diagrams (Figure 5)
Summary
A country’s mineral wealth is considered to be an important economic factor and is linked to the economy of the country. For open-pit mine monitoring, it is still possible to use GNSS to determine geodetic points and tachymetry with using the total station (TS). The main idea of the scientific study is the application of geodetic methods to capture the current extent of mining in the open-pit mine. It is an overview of the used measurement technologies, implementation of geodetic measurements, processing of measured data (data), evaluation of the state of the spatial distribution of the quarry, and the intervention of mining into the landscape. The expected results of the study will create a 3D model of the open-pit mine as a result of surveying measurements carried out in two time periods, determine the volume of the extracted mineral. Concerning the main points of the study’s direction, the study is dedicated to experts in the field of geodesy, geology, and environmental engineering
