Usage of largescale mining equipment making the work more efficient and easy Disadvantages Polluting the streams by releasing potentially harmful toxins Surface mining involves clearing large tracks of land leading to deforestation and ecological disturbance Risks related to spills and leaks is also increasedFurther Details
Jan 01 2019 · Surface mines continue to implement highwalls for several reasons such as increasing recovery improving margins and justifying higher stripping ratios Highwall stability is a complex issue that is dependent upon a variety of mining and geologic factors and a safe design is necessary for a successful surface operationFurther Details
Openpit Mining Removing ore to leave a crater Quarrying An openpit mine for construction materials Strip Mining Ore is removed in parallel strips Mountaintop Removal Top of a mountain is blasted to remove deep ore Dredging Ore is removed from a river bottom The main methods of underground mining are Room and Pillar Mining Removing ore while leaving behind some for roof supportFurther Details
Other mining companies such as BHP are starting their foray into the autonomous world but as this is still very new technology we are uncertain of the benefits and pitfalls on a longterm scale At the moment we are still in the learning stages of autonomy in vehicles but needless to say it will be interesting to watch unfoldFurther Details
Mar 25 2020 · Opencast mining also known as surface mining or strip mining has disadvantages that include disturbance of the environment and local ecosystems exposure of radioactive elements and contamination of freshwater sources The use of heavy machinery and blasting techniques also create environmental pollutionFurther Details
Sep 18 2015 · The Unmanned Surface Vehicles USV or Autonomous Surface Vehicles ASV are vessels that operates on the water surface without any crew They are remotely controlled and can be controlled by an operator located on land or on board of another vesselFurther Details
