The surface miner milled through this area at the same depth with no discernible 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 subbase for diversion roads constructed during the course of the project.
A valuable natural resource, limestone has many uses in construction, agriculture and industry. Limestone quarries can be above ground or underground, and can cover large areas. Environmental hazards from mining operations depend in part on the location, characteristics and extent of the mining .
