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.

大地露天条件下大地测量方法的应用:以斯洛伐克为例

采矿,特别是露天采矿,对包括动物群和植物群在内的土壤覆盖层的上部产生重大影响。本文涉及大地测量方法的使用,以观察采矿过程及其对环境的可能影响。创建的模型可用于设计露天矿关闭和采矿终止后的回收和填海。对于露天矿的建模,使用了来自大地测量两个阶段的2151个点。大地测量的图形表示与航空摄影测量数据进行了比较。测量和处理结果用于可视化露天矿的空间变化,这对于采取与受采矿影响的景观恢复相关的措施是必需的。根据计算,145.266 m 3是在勘探期间提取的。在计算每个工作日的平均挖掘量时,发现在监测期间之间每天提取188 m 3 = 500吨= 0.5千克。在比较露天矿的原始表面和生成的模型时,发现岩体的整个顶部被永久性地移除,总体积为3,421,000 m 3。为了捕获采矿对周围环境的影响,在观察期间内,Landsat 7和8的多光谱图像。集中注意力分为两个因素,地表温度和植被状况。温度图的结果表明,露天矿正成为热岛。对植物生长状态的分析证实了植被健康的快速变化。减少露天矿周围地区的状况。给出的结果表明,所选择的方法和程序适用于斯洛伐克小型采矿公司的条件。
