Underground mining method selection by decision making

Mar 01, 2009· 2.1. Studies on mining method selection. The problem of underground mining method selection has been studied in the literature. Boshkov and Wright (1973) proposed a classification system which was one of the first qualitative classification schemes. Morrison (1976) suggested a selection chart for mining method selection.

Models for Mining Equipment Selection

The Mining Method selection problem focuses on choosing the correct excavation method for the given mining conditions. Generally, this research is based on anecdotal methods, where a feasible solution is sought, rather than an optimal solution. Much of the literature on mining method selection does not discuss equipment selection modelling in

What is Bitcoin Mining and How Does it Work? (2020 Updated)

Nov 08, 2020· Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoin’s famous “blockchain”).. For this service, miners are rewarded with newly-created Bitcoins and transaction fees.
