Underground mass mining methods present several geotechnical challenges and risks inherent with block cave mining environments. Underground mining methods such as block, panel, and sub-level caving continue to be the primary choice for deeply situated massive orebodies, due to the high production rates and low operating costs involved.

Mine dilution occurs due to the mining method selected and from overbreak during the mining process. There are multiple considerations in terms of dilution. Mining methods such as block caving, sublevel stoping and room-and-pillar have mining methods which are more predictable, where dilution can be modeled using empirically generated equations.
1.2 Mining method To be able to economically mine the orebody, a bulk mining method had to be used. lock caving method A b was originally considered, but because of the qualityhigh of the rock mass, numerical modelling suggested the cave would choke itself before the orebody was completely recovered. A new mining methodas ,
Production scheduling in underground mines is still a manual process, and achieving a truly optimal result through manual scheduling is impossible due to the complexity of the scheduling problems. Among the underground mining methods, sub-level caving is a common mining method with a high production rate for hard rock mining. There are limited studies about long-term production scheduling in ...
Dec 04, 2019 Block caving The underground version of the open pit mining method where the ore body is undermined and allowed to collapse progressively under its own weight. Placer mining Examples of deposits mined by placer mining are gold-bearing sands and gravel that has settled from rapidly moving streams to slower, more stable currents.

Mining. The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.
