The issue of air quality has become a major concern, since the quality of air has deteriorated from time to time. Air quality is essential for human health and quality of life that it needs to be assessed at every location. Among the different pollutant sources PM10 was modelled for this study based on the fact that, it takes a large portion of pol...
Thesis

The rising demands for mined products lead to the extraction of materials in geologically complex regions. This calls for mining process changes and interventions driven by technology and advanced data analytics. The dynamic development of state-of-the-art sensor technologies and their potential use in mining is projected to significantly reduce co...

Accurate quantitative mineralogical data has significant implications in mining operations. However, quantitative analysis of minerals is challenging for most of the sensor outputs. Thus, it requires advances in data analytics. In this work, data fusion approaches for integrating datasets pertaining to the mid-wave infrared (MWIR) and long-wave inf...
Article
Full-text available
The increasing availability of complex multivariate data yielded by sensor technologies permits qualitative and quantitative data analysis for material characterization. Multivariate data are hard to understand by visual inspection and intuition. Thus, data-driven models are required to derive study-specific insights from large datasets. In the pre...
Conference Paper
Full-text available
The increasing advances in sensor technology have resulted in greater availability of sensor data for a wide range of applications. One such application is raw material characterization in mining operations. Sensor technologies operate over certain range of the electromagnetic spectrum and provide information on several aspects of material properti...

Full-text available
Despite significant recent advancements in the sensor technologies, the use of sensors for raw material characterization in the mining industry remains limited. The aim of the present study was to assess the utility of applying the mid-wave infrared (MWIR) reflectance data acquired by the use of a handheld Fourier-transform infrared spectrometer (F...
Conference Paper
Full-text available
The application of sensor technologies for raw material characterization is rapidly growing, and innovative advancement of the technologies is observed. Sensors are being used as laboratory and in-situ techniques for characterization and definition of raw material properties. However, application of sensor technologies for underground mining resour...
Thesis
The first objective of this work is to assess the temporal variation of Cu, Zn, Pb, Cd, Cr and Ni in sediments of the Aba Samuel Reservoir Lake, southwest of Addis Ababa. Two sediment cores with 44 and 49 cm lengths were recovered at the proximity of the dam in the south (Core 1) and at the western shore (Core 2). Sediment slices have been taken fr...

The overall aim of Real-Time-Mining is to develop a real-time framework to decrease environmental impact and increase resource efficiency in the European raw material extraction industry. The key concept of the research conducted is to promote a paradigm shift from discontinuous to a continuous process monitoring and quality management system in highly selective mining operations. The positive impact of the project will be achieved through improvements in process efficiency and resource utilization. These will increase energy efficiency and facilitate significant improvements in the environmental performance of mining operations by reducing the emissions and wastes generated. It is considered that deposits which are currently thought as economically marginal or difficult to access could become viable. www.realtime-mining.eu
