Block Caving . Block caving is large-scale mining method that allows for huge volumes of rock to be extracted efficiently. However, the development time before production starts is longer compared to other mining methods. By drawing rock from the extraction level in the lower part of the mine, a gap is created.
The company undetook a prefeasibility study in early 2012 and will continue with a feasibility study for the block caving mining method. It is expected to complete by mid-2013. It is hoped that the block caving mining method will triple the reserve base of niobium production. The new processing facility will begin its operation in 2016 or 2017.
Cave mining tips. When mining in a cave, simply light the way and skim the walls for minerals you can use. Iron ore is common, but keep an eye out for it to collect it, anyway. If you can mine deep enough, you may find useful materials such as redstone, gold, and diamond. However, you may also come across lava — the bane of careless miners.

This video describes the block caving process with 3D animation. Block Caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated over the undercut. The drawbells serve as a place for caving .
The mine was started as the Chino Copper Company in 1909 by mining engineer John M. Sully and Spencer Penrose and is currently owned and operated by Freeport-McMoRan Copper & Gold subsidiaries. The area where the mine is located is at an average elevation of .

Block Cave Mining Techniques. The most commonly used cave mining technique is block caving. Block caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining.
Jul 14, 2014· Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving. Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below. If the deposit is overlain by capping or bounded by drawing the ore.
stoping, cut-and-fill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1. Underground Mining Methods 1.1. Classification of Underground Mining Methods
Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, open-pit mining and in situ mining.

Substantial progress has been made to prepare for the transition to mining of the Grasberg Block Cave (GBC) underground mine. First undercut blasting occurred in September 2018, first drawbell blasting occurred in December 2018 and cave production is scheduled for the first half of 2019.
Block mining methods . Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into.
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

Cave mining has a high return on investment, yielding more ore per unit time and requiring fewer tools (less pickaxe and shovel durability is lost mining stone, dirt, and gravel) than other approaches. On the other hand, cave mining is also quite dangerous. Unexplored .

Rio has talked up Argyle's contribution to its understanding of block cave mining, a technique it also uses at the massive Oyu Tolgoi copper and gold mine in Mongolia. The technique, which involves mining under an ore body to allow it to progressively collapse under its own weight, lowers operating costs but requires substantial up-front capital.
