Review of Underground Mining Methods in World-Class Base Metal Deposits: Experiences from Poland and Chile

There are several massive deposits around the world with different geological characteristics. Thus, mining methods and strategies applied based on particularity of each method mine experience. Particularly, in this work, we review summarize underground exploitation some world-class base metal Poland Chilean experiences. Here, main parameters mines reported analyzed. In Poland, mainly room pillar (and variants) have been deposits. back-filling is required to maintain mine’s stability due large deposit size open areas. Chile, block caving commonly used where less development required. cave naturally filled broken material a subsidence zone generated. review, it has observed that can be effectively Some influenced selection related rock mechanics, ore recovery dilution, zone, extraction rate, key variables such as productivity, support, equipment, well various issues studied. Additionally, comparison between both experiences presented, highlighting parameters. This study reference evaluate option future projects similar
