Caving methods. Caving methods include block caving, sublevel caving, and longwall mining.For emphasis, allow me to repeat what I said earlier: caving methods are used in settings where the ore or the host rock is so weak that it cannot support its own weight for any period of time; the methods only work if the rock or the ore will readily cave under its own weight.

 · Raise caving has evolved within the framework of a larger project entitled alternative mining methods, the aim of which is to study several possible mining methods of the future. Raise caving is a versatile method which can also be applied in combination with other mining methods, for example, block caving.

Block caving

 · Block caving is a new alternative method of developing new mines or extending the operation of open pits. 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.

Stoping Mining Methods

 · Block caving is employed principally for mining low-grade ores where the inevitable loss of some ore and some dilution with capping and wall rock are permissible and where mining must be done on a large scale and at a lower cost than can be obtained by the use of supported-stope or other selective mining methods.

Block Caving Underground Mining Method

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.

8.4.2a Block Caving | ABC 123: Testing Site / Course

 · Caving Methods of Mining. There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving. In a discussion of these methods, three things must be borne in mind ...

Block caving method : mining

Block Caving is the Prime Ultima, the Quintessence, the very acme and pinnacle of mining - every engineers wet dream, every shareholders last drop of saliva, every operators heaven, a gigantic never ending continuously producing ROCK FACTORY.

Block caving

 · Another key advantage to an underground mining method like block caving, as compared to open pit methods, is the large reduction in surface waste disposal needs. As open pits get deeper, their ratios of waste rock to ore often get higher and the waste must be placed in ever-increasing surface storage areas.

Keeping up with caving

these mining methods. As caving has proven to be a safe and effective mining method, its popularity has increased around the world." BLOCK ANd pANeL CAVING Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping orebodies located at depth, particularly those with disseminated mineralisation or that are

Underground Mining Methods

Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible. Mining now proceeds underground, underneath the open pit.

Caving Mining Method Classification and Characteristics

Block caving: A new mining method arises | Geoengineer

Chapter

selecting a mining method, with the emphasis on underground mass mining techniques, such ns caving, induced caving, and stoping, is proposed. In the past, selection of a mining method for a new property was based primarily on operating experience at similar type deposits and on methods already in use in the district of the deposit.

Caving Mining Method Classification and Characteristics

 · Caving mining method is a mining method that realizes ground pressure management by caving surrounding rock. That is, with the progress of the stoping work, fill the goaf with forced or natural caving surrounding rock to realize ground pressure management.

In a discussion of these methods, three things must be borne in mind ...

Underground Mining Methods and Equipment

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 – A Viable Alternative? | Golder

Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...

Block Caving

Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization. "Block" refers to the mining layout, which divides the ore bodies into blocks and large sections.

Module 7_Underground Mining_Caving Methods_Revised

Caving methods are defined as those associated with induced, controlled, massive caving of the ore body, the overlaying rock, or both, concurrent with and essential to the conduct of mining. The following three are considered to be caving methods: - 1. Longwall mining 2. Sublevel caving 3. Block caving Longwall mining is used in horizontal, tabular deposits, mainly coal; the other methods have ...
