Block Caving Production And Mass Mining

Block caving method · Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving. Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below.

Block Caving A Viable Alternative | Golder

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.

Block Caving . Block caving is large-scale mining method that allows for huge volumes of rock to be extracted efficiently. However, the development time before production starts is longer compared to other mining methods. By drawing rock from the extraction level.

Jul 25, 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.

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.

Dec 01, 2018 · 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 lower- grade ore deposits with substantial vertical dimension.

Block caving is an efficient mass-production method for the underground mining of large orebodies. However, the block-caving method requires a substantial investment in developmental works, based on the assumption that the rock will cave. Efficient block caving is prevented if the rock forms stable arches or breaks into fragments that are too large to pass easily through the finger raises.

Jul 10, 2018 · In the right conditions, the advantages of block caving make it an alternative that is now being considered more often, such as at Seabridge’s KSM Project. 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.

Later in the schedule, the company is also targeting the outlying Kucing Liar orebody for block caving. In the meantime, FCX converted its DOZ orebody, which it began mining in 1989 using open stoping, to block caving in 2000, with production expected to continue until 2019.

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining.

Mass mining including block caving, incline caving, front caving, sub-level caving and sub-level retreat are the principal mining methods for primary diamond deposits worldwide. Diamonds have only been mined on an industrial scale within the past 150 years, mainly as open pit mines.

Block caving method · Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving. Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below.

Accounting For Micro-Defects In Rock Mass Rating. In 2001, Laubscher’s Mining Rock Mass Rating (MRMR) classification system (Laubscher and Jakubec, 2001) introduced the rock block strength concept to account for scale effects and the influence of closed defects on intact rock strength (IRS).

The term block caving is used for all types of gravity caving methods. There are three major systems of block caving, and they are differentiated by the type of production equipment used. (1) The first system based on the original block cave system is the grizzly or gravity system and is a full gravity system wherein the ore from the.

Determination of optimum drawpoint layout in block caving using sequential Gaussian simulation mining methods, block caving is typically a large-scale method and one of the few economical.

This report has been intended to provide a simple understanding of the block cave mining method and the production process involved. This report is advocated towards a layman in block caving in view of getting an impression about the block cave mining method. Chapter One – Introduction 1.1 Block Caving.

Initial capital investment for the mining methods ranged from $77,200,000 for chamber and pillar, to $122,872,000 for block caving, using LHDs. Mining costs, including all direct, indirect and.

Oct 23, 2014 · Caving Underground Mining Methods (longwall, Sublevel caving, & Block caving) 1. This material is intended for use in lectures, presentations and as handouts to students, and is provided in Power point format so as to allow customization for the individual needs of course instructors.

The vertical nature of the deposits allows for block cave production with high ore columns and low dilution. Golder helped determine that block caving could be done with an operating cost similar to that of the open pit as it deepens. Just as importantly, block caving would be able to deliver the volumes of ore comparable to open pit mining.

Cave Mining Cu-Au Porphyry. There are over 45 cave mining projects in various stages of studies and development around the world. Cave mining methods will be the underground method of choice in the future. It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential.

Mass Mining Diamonds. Mass mining including block caving, incline caving, front caving, sub-level caving and sub-level retreat are the principal mining methods for primary diamond deposits worldwide. Diamonds have only been mined on an industrial scale within the past 150 years, mainly as.

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.
