Sublevel caving (SLC) is a mass mining method based upon the utilisation of gravity flow of blasted ore and caved waste rock [1].The method functions on the principle that ore is fragmented by blasting, while the overlying host rock fractures and caves under the action of mine-induced stresses and gravity [2].The caved waste from the overlying …

The development stage of block caving infrastructure needs 3-5 years until ready for continuous production. The existing block caving projects have a life of mine for production, ranging from 12 to 35 years. Thus, we propose a long-term concession, about 15 until 40 years, covering development and operational production stages.
suitable block sizes without blasting. fragmentation must be known beforehand as it influences: • drawpoint spacing • amount of secondary blasting • hangups and delays • production rates and draw control • drawpoint and drawbell size • equipment size and type • ramp up period. fragmentation
The Ridgeway deposit is centred on multiple steeply-dipping porphyries occurring at the confluence of two gently-dipping structural blocks. To the west of Ridgeway, stratigraphy gently dips east, whereas sedimentary units to the east dip west to west–northwest at 10–20°. These rocks are cut by multiple moderate-dipping reverse faults.

The large porphyry system at Cadia Valley Operations contains a number of deposit styles and structural settings including one of the world's highest grade gold-rich porphyry's at Ridgeway. The Ridgeway ore body, which has no surface presence, lies around half a kilometre below the surface and resembles an invert…
The undercutting process is a technique employed to initiate the caving of the ore mass in block caving, achieved by creating a basal cut on the block scheduled to be submerged. The effective execution of …

Sublevel caving was initiated at the Ridgeway Gold mine in May 2000 A seismic system was used to monitor the progression of the caveInitial marker experiments were undertaken in the Ridgeway sublevel cave (RW) (2002), and subsequently at Ridgeway Deeps (RWD) (2008) and Cadia East PC1 (CEPC1) (2012) block caves Over 25 000 markers have …
The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability to maximise investor returns through the use of very high lift heights at depths ...
The use of block caving to mine deep, massive, low-grade ore bodies is gaining increasing attention from the mining industry given its merits in terms of safety, tonnage produced and costs that can match those of open-pit operations. However, the undercutting and bulk extraction of ore through caving (Kendorski, 1978; Brown, 2003), leads to the ...
O método Block Caving envolve o desabamento controlado de grandes blocos de rocha por seu próprio peso através de fissuras e fraturas. Isso requer rochas com facilidade de fragmentação em profundidades entre 600-1200m. O método possui altas taxas de produtividade e baixos custos, mas também riscos de subsidência e diluição do minério.

Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: • Longwall mining • Sublevel caving
Block Caving is an underground mining method in which high productivity and low operational costs are expected when applied to thick low-grade ore bodies. 1, 2 Using this process, the broken ore is extracted from the bottom of the ore body after the initial undercutting. The undercutting induces progressive rock mass caving due to …
