Mining And Mines Block Caving

Block Caving. 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 ...

Block Caving A New Mining Method Arises

Jul 25, 2018 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.

An Overview Of Block Caving Operation And Available

Block caving is a technique in which gravity is used in conjunction with internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. Block refers to the mining layout in which the ore-body is divided into large sections of several thousand square meters. Caving of the rock mass is induced by ...

Inside Block Caving The Deep Mining Method Of The Future

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. According to Suorineni, caving heights have also increased drastically from about 200m to 500m, creating so-called super caves.There is insufficient experience caving in these environments, he adds, which is a ...

Study On The Rock Mass Caving And Surface Subsidence

To deeply understand the mechanism of the rock mass caving and associated surface subsidence during sublevel caving mining, the Xiaowanggou iron mine was selected as an engineering project case study. The study area was analyzed by means of an in situ geological investigation and numerical simulation. First, a borehole television BHTV system and a GPS monitoring system were used to

Inclined Caving As A Massive Mining Method

The mine was founded in 1961 and started surface-mining in 1964. Underground production commenced in 1990 using a Modified Blast Hole Open Stopiog method for the mining of Blocks 1,2 and 3. Block 4 is currenHy being mined as a BibCk Cave. The process of identifying and optimising a mining method to mine the Block 5 ore

Raise Caving Cheaper And More Flexible Mining At Great

May 31, 2021 Mass-mining methods, such as block caving or sublevel caving, enable low-cost and efficient mineral extraction, but these methods are associated with high capital cost and risks. Latter mining methods call for mine planning and decision many years in advance. Moreover, block caving and sublevel caving are difficult to apply in at great depths due to the high prevailing stress conditions.

The Block and Sublevel Caving Symposia provide a platform for mining companies to be kept informed of the latest technological developments and caving research carried out by industry and academia. The Australian Centre for Geomechanics, a not-for-profit mining research organisation at The University of Western Australia, looks forward to ...

Interaction Between Block Caving And Rock Slope

This paper is part of a special issue on Block Caving Introduction With the increasing global demand for mineral resources, underground mass mining methods like block caving are increasingly being promoted to mine lower grade porphyry copper deposits due to the low cost and high productivity that can be achieved. This includes open

Block Caving Mining Magazine Redpath Mining

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 low-grade in nature, but too deep to be extracted using open pit methods. Block caving also depends on insitu stresses and

Block Caving Canadian Mining Journalcanadian Mining

Some deposits are either too deep to economically extract by open pit methods or are of insufficient value to justify other more costly and conventional underground methods. In the right conditions, the advantages of block caving make it an alternative that is now being considered more often. Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively

Hydraulic Fracturing Amp Block Caving Systems Acim

While the concept of block caving as a mass mining process is not new, the benefits of cost and increased production makes it an attractive process. The method involves mining deep, large and low grade Ore bodies whereby a large section of rock is undercut, creating an artificial cave that fills with its own debris as it collapses.

Of primary concern, with production targets between 130,000 and 160,000 tpd, drawbells must open at a sufficient pace to achieve acceptable caving production ramp-up and then maintain throughput targets. Detailed undercut scheduling alleviates those concerns by optimising production block start dates,

Definition Of Block Caving

Definition of block caving. A general term that refers to a mass mining system where the extraction of the ore depends largely on the action of gravity. By removing a thin horizontal layer at the mining level of the ore column, using standard mining methods, the vertical support of the ore column above is removed and the ore then caves by gravity.
