Evaluation of shaft locations in underground mines:

2019-11-11  There have been limited studies of vertical shaft issues in underground mining. Unrug (1984) examined important aspects such as shaft location selection, the design of shaft lining and collar, and sump design. The author emphasized that a shaft could be located on the footwall side of an ore deposit with a major axis in the strike direction.
