Over the past decade unmanned aerial vehicles UAVs have been used in the mining industry for various applications from mineral exploration to mine reclamation This study aims to review academic papers on the applications of UAVs in mining by classifying the mining process into three phases exploration exploitation and reclamation Exxaro Mining Operations As the countrys second largest earner after gold coal provides 61 of the countrys total merchandise exports South Africa is fortunate to hold the sixth largest coal reserves in the world estimated to total 31 billion tonnes of recoverable coal 11 of the worlds total Leigh Creek Energy plans to produce energy from coal using a process known as underground coal gasification UCG also known as Insitu Gasification ISG The UCG process converts coal from its solid state into a gaseous form resulting in the generation of synthesis gas syngas containing methane hydrogen and other components

sometimes referred to separately as coal mining geology follows on after the mine begins operation Coal mining geology embraces a number of special skills and techniques but is otherwise essentially a continuation of exploration activities into the production phase of the project 2 Objectives of Coal Exploration Programs Mining operations are also often conducted in remote locations where access to spare parts and large maintenance facilities may be difficult Current research has focused on the development of sensor systems that can be incorporated into large vehicles and heavy machinery to monitor continuously the state of the health of the vehicle Remote Sensing and Geophysics these services cross the project life cycle from earlystage exploration through development and operations to closure pressure development in the pit walls as the mine expands and to gauge the impact these elements will have on future mine operation and pit slope stability Learn More

Mining beneath ground water reservoirs rivers seas and harbours has been successfully carried out in numerous countries for many decades The risks and engineering considerations have been refined over a long time to enable safety and geotechnical outcomes to be defined and adequately controlled The experience in Australia has been a prolonged debate over three decades between the mining Openpit mining Some 53 of South Africas coal is produced from surface mining via opencast or openpit mines This is because the coal is less than 60 metres below the surface Openpit mines use draglines as well as truck and shovel operations to extract coal A dragline excavator uses a dragline to pull a bucket by a wire cable PROPOSED COAL MINE PROJECTS CROWN MOUNTAIN COAL MOUNTAIN PHASE II NWP Coal Canada Ltd Marten Wheeler 749 Mt MI 17 Mt per year 16 year mine life Open pit operation Preapplication stage of EA Teck Coal Limited 225 Mt per year 34 year mine life Open pit operation Preapplication stage of EA FORDINGSWIFT

Campbell 1994 Geophysical techniques can be applied at almost any scale and at any stage of a mining operation to provide a performance benefit Four broad classes of application can be recognised ore body delineation to maximise ore recovery and minimise dilution rock mass characterisation to guarantee safety and to optimise Coal mining Coal mining Choosing a mining method The various methods of mining a coal seam can be classified under two headings surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods and the choice of which method to use in extracting a coal seam depends on many The mining industry plays an important role in all 50 states In 2009 an estimated 1400 mines were operating in the United States1 As a supplier of coal metals industrial minerals sand and gravel to businesses manufacturers utilities and others the mining industry is vital to the well being of communities across the country
