dc.description.abstract |
Sri Lanka is rich in industrial minerals, including graphite, apatite, ilmenite, rutile, quartz,
feldspar, kaolin, apatite, garnet sand, mica, calcite, and dolomite. Even though lots of mining
methods are used to extract such minerals, only limited studies have been carried out in Sri
Lanka to evaluate mining methods by means of main mining principles, such as safety,
economy, and efficiency. This study focuses on the Bogala graphite mine, a narrow vein
medium depth underground mine, and Aruwakkalu limestone open pit mine. To evaluate the
overhand cut and fill mining method in Bogala mine, Equivalent Linear Overbreak or Slough
(ELOS), which is a useful measurement for quantifying the unplanned dilution in narrow vein
mining, is used. The favourability of the underground mining method is evaluated for a
particular mine site using Key Deposit Indicators (KDIs), and it provides the best suited
underground mine based on characteristics of the ore body. The fracture system presence in
the Bogala mine requires a good support system to ensure the safety of underground workers.
The efficiency of the loading and hauling equipment in the Aruwakkalu mine site is evaluated
by Match Factor (MF). |
