Geological Visualization Tools and Structural Geology Geologists use several visualization tools to understand rock outcrop relationships, regional patterns and subsurface geology in 3D and 4D.

Group of Knowledge - Edumine

The original design of the LHD block caving system incorporated the drilling of the draw bells from the undercut level to ensure proper blasting sequence. Today, the draw bells are developed entirely from the production level and the blasting is started by drilling a raise in the centre of the draw bells.

Cave management at Finsch Mine J - SAIMM

For any block cave draw control is the key to success. If draw from the cave is not managed, many problems are encountered, including rat holing, premature waste ingress and recompaction, which can lead to tunnel collapse. De Beers has been running block caves at Kimberley and Cullinan since the early 1900s and front cave at Koffiefontein prior to its sale in 2006, with mixed success. Finsch ...

Draw rate optimisation in block cave production scheduling ...

Draw rate optimisation in block cave production scheduling F Nezhadshahmohammad et al. using mathematical programming 310 Underground Mining Technology 2017, Sudbury, Canada Caveability, in the context of draw control, is primarily concerned with balancing caving rates and production. If draw rates are not controlled, either air gaps or damaging stress concentrations may occur. ...

The Block Cave Mining Method - UK Essays

The factors to be considered include geotechnical constraints, cave shape, draw point development sequence, draw point productivity, production block limits such as loader capacity and ore pass capacity and variable shut-off grade mining costs. The nature of the problem also changes during the life of a cave from initial production build up to final closure.

Pitram: Block caving - MICROMINE

Pitram: Block caving Pitram is a mine control and management reporting solution that can capture all mine related events of an underground block cave. Centred around a Control Room, Pitram provides a single environment for management and supervisors to make informed decisions related to the development and production of the cave. Pitram's decision support tools improve the implementation …

Block caving - QueensMineDesignWiki

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.

Block Caving Cu-Au Porphyry - SRK

Cave mining is the primary underground mining method for extracting large Cu- Au porphyry deposits and this talk will highlight some of the recent development and challenges.

Evolution of Block Size Distribution ... - Cave Mining Forum

Cave Mining Forum - Workshop II This presentation will cover the evolution of block size distribution (BSD) within a draw column during block cave mining. BSD plays an important role in controlling gravitational flow, secondary fragmentation, and fines migration in broken ore—all of which are fundamental in preparing a reliable feasibility assessment for a potential caving operation.

STUDY OF THE INFLUENCE OF INTERACTIVE DRAW UPON …

These results have led to significant new understandings about the influence of interactive draw upon drawpoint spacing in block and sublevel caving mines. The drawpoints must be spaced less than ...

A MODEL FOR GRAVITY FLOW OF FRAGMENTED ROCK IN BLOCK ...

The work in this thesis is directed towards the development of a model for gravity flow of fragmented rock that can assist in the design of drawpoint layouts and draw schedules in caving mines.

INCLINED CAVING AS A MASSIVE MINING METHOD DDMunro …

Block Caving was selected as the mining method for Finsch Block 4 with the main driver being the risk of sidewall failure in the pit if the Blast Hole Open Stoping method had been continued which would have diluted the ore being mined.

Download Developments for Continuous High-Performance ...

For this study, the mine design was set for a panel caving operation with a typical draw point spacing of 15 x 15 m and a characteristic average block height of 560 m. The ore density is set to ρ=2.7 t/m 3 .

Palabora Mining Company Ltd

The block height of the cave reaches a record 450 meters in the centre, increasing up to 700 meters on the periphery, rendering Palabora a world-class mine. Geographically, the production footprint is very small, measuring 650 meters in length and 200 meters wide, with 20 production cross-cuts and 320 draw …

3D Large Scale Physical Modelling for Studying …

In block caving mines, the gravity flow of caved (broken) ore controls the amount of valuable material recovered and the extent to which it is diluted by caved waste rock. In addition, it also dictates the spacing, and thus the number of drawpoint required, which has a large impact on capital

Pitram: Block Caving - micromine.com

Pitram: Block Caving Reduce Costs. Maximise Profits. When mining a block cave, it is essential that the development and production stages are conducted efficiently, and adhere to mine and draw control plans to ensure reduced costs and maximum profits. Mine Development There is generally a greater financial investment in the development of the block cave than the production of it. Poor ...

above the draw horizon or from the draw points. Block cave development using an advanced undercut system. In this system the country rock development is advanced to the ore body and the undercut front is advanced before the draw horizon has been developed. The draw horizon and draw points are then developed in destressed conditions. The use of this system normally requires the development of a ...
