block caving production and mass mining

  • Block Caving Production and Mass Mining MDA

    Block Caving Production and Mass Mining MDA’s Surface Asset Monitoring block caving service offers timely monitoring of block caving operations to within millimeter-level accuracy using Interferometric Synthetic Aperture Radar (InSAR) technology.

  • What every mining professional needs to know about block

    Touted 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 lower-grade ore deposits that are vertical in orientation. The method is an attractive alternative when planning to develop a new mine, or to extend the life of an open pit operation.

  • block caving production and mass mining

    block caving production and mass mining Block caving is an underground mass production system of ore extraction which, under favorable conditions, gives lower mining costs than any other underground method. However, it requires relatively large capital expenditure in terms of preliminary development and infrastructure establishment.

  • mining and mines: 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.

  • Block caving: A new mining method arises Geoengineer.org

    25/07/2018· 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.

  • Block caving: A new mining method arises

    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. This broken ore falls into a pre-constructed series of

  • Block Caving Mining Fundamentals

    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. Caving of the block

  • Hydraulic Fracturing & 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. As a result, a pre-constructed series of funnels and access

  • THE OPTIMAL BLOCK SIZE IN THE BLOCK CAVING MINING

    THE OPTIMAL BLOCK SIZE IN THE BLOCK CAVING MINING METHOD J. Someehneshin 1, K. Oraee 2, production is low. Block caving is described by Laubscher (1994) as the lowest cost underground mining method provided that the extraction layout is designed to suit the caved material and the draw horizon can be maintained for the life of the draw [4]. A wide range of minerals including Gold, Copper

  • Increasing productive capacity in block caving mines

    Keywords: discrete event simulation, block caving productivity, continuous production system 1 Introduction Block caving provides a cost-effective alternative to extract low-grade underground operations by applying mass mining methods across large mineral deposits (Laubscher 1994) under the appropriate conditions.

    Block-caving, Cavability, Block Size, Length and Width of the Block, the Optimal Block Size in Block Caving Method INTRODUCTION In 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

    01/05/2018· Block caving is an underground mass production system of ore extraction which, under favorable conditions, gives lower mining costs than any other underground method. However, it requires relatively large capital expenditure in terms of preliminary development and infrastructure establishment. Block caving is suited to massive orebodies with a well-disseminated grade. 21 Additional features

  • Cave mining: 16 years after Laubscher's 1994 paper 'Cave

    29/11/2013· This paper supplements a keynote address prepared for the 2010 Second International Symposium on Block and Sublevel Caving. The author gauges the cave mining industry's position (practice and theory) since the publication of what he considers a seminal paper on 'Cave mining state of the art', hence '16 years after'.
