The Impact of Mining Fluids on Enhanced Oil Recovery

The development of enhanced oil recovery (EOR) technology has sparked a new oil boom in America. Also known as tertiary mining, EOR is a variation on hydraulic fracturing ("fracking") that has enabled American oil producers to more than double the amount of oil and/or natural gas recoverable from otherwise tapped-out reservoirs.

Parameters influencing full scale sublevel caving

The major disadvantage of the SLC mining method is the relatively high dilution of the ore by caved waste, .A major factor influencing this dilution is the flow behaviour of the ore and waste material,,, .Despite its importance on SLC performance, the mechanics of gravity flow of blasted and caved material is historically not well understood .
