Inside block caving: the deep mining method of the future

14/02/2020· The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is aRANKED: Top 10 lowest cost copper mines MINING.COM,A majority of copper operations in the top 10 use truck & shovel technology, with the exception of El Roble (drift & fill, cut & fill), Carrapateena (sublevel caving), Jabal Sayid (long holeCopper Mining and Extraction Sulfide Ores,The British Geological Survey and Smithsonian Institute have sites and apps that will show you the current and historical volcanic activity.
