In summary, there are three dominant techniques worldwide for mining gently-dipping narrow vein: Longwall mining method: this method is suitable for mining bedding deposit with a dip less than 35°, 3-4 m thickness and poor roof.
In this paper, a practical long-term plan and schedule for an underground mine located at Costerfield in Victoria is presented, discussing all main areas of concern regarding narrow vein mining. Enhanced production scheduler (EPS) software is the current tool that is used for long-term planning and production scheduling at this mine.
1 de ene. de 2021 · This article is focused on underground mining of narrow-width deposits (veins) and the role of economic geologists in the definition and development of these deposits.
Reducing Selectivity in Narrow-Vein Mining through the Integration of Underground Preconcentration. Malcolm Scoble. 2000. The introduction of pre-concentration technology into the underground narrow-vein mining scenario has the potential to change the entire economics of utilizing bulk-mining methods in these situations.
To sustain production from the underground mine, engineers examined an alternate mining method that would allow extraction of the periphery domains that were once deemed “sterilised”. Several methods were considered with the only practicable solution a style of sublevel caving (SLC).
27 de oct. de 2021 · External dilution in underground open-stoping exploitations is a matter of paramount importance for the proper operation and cost-effectiveness of the mining process. Dilution can be defined as the ratio of the tonnage of waste mined and sent to the mill to the total tonnage.
1 de dic. de 2019 · In respect to the underground mining of narrow veins in hard rock, thermal fragmentation provides a degree of competition to the methods generally relied on for the extraction of ore, such as longhole open stoping, shrinkage stoping, cut-and-fill and resue mining.
