In-Situ Bitumen Extraction | Oil Sands Magazine

In-situ facilities therefore have a much smaller footprint than surface mining operations. In-situ requires about 1/7th the land area of an equivalent-sized mining facilities. Alberta's oil sand mining footprint is actually only 3% when measured by square footage.

Limestone - Global Surface Mining

The surface miner milled through this area at the same depth with no discernable change in production levels. The limestone produced was of a much smaller and consistent grading than that produced using traditional mining methods, which meant it could then be used as sub-base for diversion roads constructed during the course of the project.
