No. 1: Data and analytics help to improve equipment efficiency and utilization The first thing you notice walking into a mine's operational center is the amount of information flowing through the large screens that wrap the walls.

Comprehensive exploration is the simultaneous exploration of associated minerals and paragenetic minerals while exploring major minerals. It can improve resource utilization and economic benefits and reduce exploration costs. These are all issues that should be paid attention to in mineral exploration work. 1.

Mining is a very capital-exhaustive industry, and it is an undeniable fact that the equipment utilization and correct assessment of these setups are very significant. Mining sectors need to utilize their equipment as efficiently as possible to get the primary yield on their investments and reducing production cost as well [ 1 ].

The best probable utilization of equipment can be possible when the probability of equipment is readily available; the consequence of this should lead to an increase in the production levels of equipment. Enhancement of machinery availability can be possible through a reduction in the downtime hours. ... B.S. Dhillon, Mining …
