Block caving is an extreme case of sublevel caving in which instead of a back of ore 5 to 10 ft. thick, one 50 ft. thick is undermined and allowed to cave. The method is illustrated in Fig. 7. After the bottom of the block, or panel, is cut up into pillars by drift's and cross drifts, the pillars are robbed, and then the remaining stumps are ...

MACLEAN ORE FLOW SUITE FOR BLOCK CAVING (BULK MINING) - WHAT AN UNDERGROUD MINE NEEDS TO BEAT THE CHALLENGE OF ORE FLOW BLOCKAGES. The MacLean Ore Flow Suite for Block Caving (Bulk Mining) is what an underground mine needs to beat the challenges of ore flow blockages like drawpoint hang-ups and oversize that seriously impact productivity and increase overall mining .
A look at the underground mining process The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here's how it works. Ore, rock containing . Continued
Jul 25, 2018· 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.

Palabora Mining Company operates a successful underground block-cave mine, producing 80,000 tonnes of copper ore per annum. Palabora's block-cave mine is a benchmark for integrated design. No other block-cave mine has been put into as competent an ore-body. The block height of the cave .
In 2023, PT-FI expects to produce an average of 130,000 t/d of ore from five production blocks spanning 335,000 sq.m in the large-scale Grasberg Block Cave underground mine. At average reserve grades of 0.96% Cu and 0.72 g/t Au, this is expected to equate to production of .
Through its subsidiary, PT-FI, FCX mines one of the world's largest copper and gold deposits in the Grasberg minerals district in Papua, Indonesia. In addition to copper and gold, PT-FI produces silver. FCX has a 48.76 percent interest in PT-FI and manages its mining operations. PT-FI's results are consolidated in FCX's financial statements.
After many years of hard work in PT Freeport Indonesia's Grasberg Block Cave (GBC), the project is now well into its transition from Mine Development into Mine Production.

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
Bulk 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 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.
Block caving operations are also susceptible to external mudrush flows because the broken muckpile connects the surface with the underground excavations. Although mudrushes are more common in caves than in other mines, any mining activity that enables the accumulation of fine particles and water is susceptible to mudrushes.

Block Caving. Block caving is essentially the underground version of open-pit mining. It's the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
