Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the LHD system for very coarse material. Full gravity ...

Block cave mining has been referred to as a safe mining method mainly due to the limited volume of supervision areas, focused work areas, smaller work force requirements and higher amount of mechanizations. Even with these advantages towards block cave mining method there are hazards involved towards safety and many of these dangers have been highlighted in the statement.

Block caving has emerged as a cost-effective method of mining large, low-grade mineral deposits. 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.

Mining - Mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

applies the gravity caving mining method, producing 1.8 Mt/y ROM utilising a slusher layout and rail transport to the hoisting shafts. The deeper zones form the largest mineral resources at the DNK mine and are planned to be developed in the next several years. At this depth, the generally poor ground conditions, combined with the high in-situ stress state will potentially lead to extremely ...

Flow dilution would (based on this definition) be essentially unique to cave mining methods. Flow dilution is, therefore, very dependent on the various flow mechanisms, some of which are described later. People will often refer, in a general manner, to the amount of dilution expected for a block cave. Figures of 10% to 20% are common.

Cave mining (both block caving and sub-level caving), which is currently used at Petra's underground mines in South Africa is a well-established and safe mechanised mining method that was first introduced at Kimberley, South Africa in 1951. It is now used extensively as an underground mining method as it allows for the bulk mining of large orebodies and enables a higher ore extraction ...

This method also suits scenarios where ore continues below final open pit bottoms. Because caving techniques can be used across all mineral commodities with the correct ...

Syama is well suited to the sublevel caving mining method because of its scale, width, orientation, and uniformity of grade. Unlike other bottom-up caving methods (block cave, panel cave), sublevel cave mining is a top-down method and therefore does not require large initial investments in mining infrastructure prior to commencement. The Syama sublevel cave commenced on the 1105 level with .
