I'm Thanujan, final year undergraduate. I'm doing the research on 'Critical Evaluation of Industial Mineral Mining Methods in Sri Lanka' which includes both Underground & Surface methods. We have identified the practicing mining methods as following,
Underground Mines (Graphite):
*Cut & Fill Mining
*Open Stoping method
Beach Heavy Minerals (Ilmenite):
Openpit mines (Limestone, Apetite):
*Single bench mining
*Multi bench mining
*Undeground & Surface methods
Firstly, classification of some methods are being doubtful as there no proper mining methods are practiced,
beach heavy minerals - scraping the beach by bulldozers
apetite - scraping a hill by bulldozers
gems - underground pits or scraping by bulldozers
How can we classify these kind of mining methods?
Furthermore, during the evaluation we have to consider different factors for the differnt methods mentioned above.
What are the main factors should we consider for each methods?
Are there any pre-established systems for the mining method evaluation?
Your help will actively assist our research project..
Thank you in advance..
