Thermal Fragmentation Mining Method - Nippon

Thermal Fragmentation Mining Method An extraction process with multiple benefits that solves the challenges of today. The extraction process allows thermal fragmentation with an accuracy of 2 cm to quickly extract any type of hard rock up to 110 cm wide. With such precision, high grade precious and base metal veins can now be extracted without ...

Bringing the heat: thermal fragmentation comes of age

A new technique called thermal fragmentation, unveiled last November, may be able to do the job, and be a greener method. Waste not want not. Thermal fragmentation has been in development since the early 2000s but the technique really came into maturity around seven years ago. Essentially, it involves using heat to shatter or ‘spall’ rocks.

The Block Cave Mining Method - UKEssays

Chapter One – IntroductionConsiderationsChapter Two -Production ProcessChapter Three – Production ControlBlock caving is an underground mining method applicable to the extraction of low-grade, massive ore bodies with the following characteristics: 1. large vertical and horizontal dimensions, 2. a rock mass that will break into pieces of manageable size, and 3. a surface that is allowed to subside.These rather unique conditions limit block caving to particular types of mineral deposits. Block caving is used for extracting iron ore, low-grade copper, molybdenum deposits, and diamond-bearing kimber...

Blast Optimization and Ore Fragmentation Modeling

Modelling Blast FragmentationOptimization of Unit OperationsOptimization of Fragmentation in An Underground MineComparison of Costs of Mechanical and Explosive ComminutionThe common denominator in all models of fragmentation is the influence of rock properties and geologic structures within the blast. A simulation approach which attempts to accurately replicate the fragmentation process will necessarily be complex and difficult to apply to a wide variety of geologically dissimilar sites. The Kuznetzov equation has the advantages of being well suited to statistical fitting to general rock conditions and blast design. Combining this with a Rosin-Rammler type dis...

2010-2-2  fragmentation plays an important role in order to control and minimize the loading, hauling, and crushing costs. The size distribution analysis of the rock fragmentation by sieving is a direct and accurate method but it is very time consuming and costly. Fragmentation analysis by digital image processing is a low cost and quick method.

Block caving: A new mining method arises

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.
