Advantages of block caving method of mining

study of the influence of block caving underground miningjun , · block caving mining method is one of the most viable and preferred mass underground mining methods for low grade orebody. however, in combined surface and underground mining, the breakthrough of an underground caving under an open pit may result in subsidence at the bottom of the pit. this can pose a serious threat for the stability of the pit and the safety of the miningblock caving queensminedesignwikithe time taken to establish caving operations varies, and it is not uncommon to take a period of at least 10 s from the time of study commencement to achieving project approval. for some largescale planned caving operations, studies have been under way for more than s with a final decision still yet to be made. the early stages ofselection considerationsplanninginfrastructure requirementscase studiescaving is a nonselective, bulk mining method. it requires largescale mineralisation in all three dimensions (length, width and height), in rock conditions that are sufficiently weak to allow caving and have suitably fine fragmentation, yet strong enough to ensure that the excavations will last the 10 to 50 life usually associated with caving operations, although preconditioning can be used to weaken rocks that would otherwise be unsuitable.it cannot be stressed enough that the size and orientation of the the orebody is an important detercave mining techniquesblock caving is a largescale mining method that is particularly useful for mining lowgrade or disseminated ore bodies which are at too great a depth to be exploited through opencast mining. this miningwhat every mining professional needs to know about blockoct , · described as the deep mining method of the future, block caving is an underground mass mining method that allows for the bulk extraction of large, relatively lowergrade ore deposits that are vertical in orientation. the methodblock caving a new mining method arises jul 25, · 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,estimated reading time 3 minscaving mining method classification and characteristicsaug 03, · 2. characteristics.

The case of block caving method of mining

block caving canadian mining journaldec 01, · 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 pitsinside block caving the deep mining method of the future?feb 24, · block caving could be the mining system of the future, according to fidelis suorineni. block caving is a mining system which involves undermining an ore body and then allowing it to collapse under its own weight, a process that opens access to deeper deposits. professor fidelis suorineni of the nazarbayev university of miningestimated reading time 5 mins4.3.2 underground mining methods abc 3 testing sitecaving 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 methodsthe optimal block size in the block caving miningin classification of underground mining methods, caving methods are regarded as high production methods. these techniques are usually very costly and need great preparation. however, the high production rate of these methods, make them costeffective . the block caving methodblock caving mining industriesprepared by gift. g. dembetembe. 1 method overview block cave mining is a mass mining method that allows for the bulk mining of large, relatively lower grade highly fractured orebodies.. 2 cont block caving is characterized by cavingmining method resolution coppermining. the most viable way to recover the ore body is by a wellestablished underground mining method called block caving. block caving is safe, environmentally sound, and costeffective for mining a large, deep orebody. in block cavinggem mining methods explained blogs stonebridge importssep 05, · 2. block caving a method commonly used to mine diamonds, block caving consists of undermining a gembearing rock (400 to 600 feet below) then having it collapse naturally through itsstoping mining methodsapr 03, · block caving is employed principally for mining lowgrade 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 supportedstope or other selective mining methods.
