surface mining ratios

Land Use Analysis of Existing and Potential Coal Surface

Ratios of Surface to Underground Mining Coal will be mined by surface and underground methods. Given a total demand for coal, the proportion of this coal which will be surfacemined is the single most sensitive factor in the estimation of land use impacts due to surface mining. Within any state, the greater the fraction to be surface

TV:BIP Ratio Explained: The Economics of Oil Sands Mining

Apr 30, 2016Most mined oil sands deposits are located within 50 meters from the surface. The strip ratio (SR) is the simplest measure of mining efficiency. Defined as the weight of overburden (or waste ore) divided by the weight of oil sands ore, a strip ratio of 2 is considered high but feasible if the ore grade is high enough.

Surface Coal Mining Methods in Australia

Largescale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and operating at higher stripping ratios (Westcott et al., 2009).
