Shaft sinking Wikipedia

Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top

Timing and Duration of Subsidence Due to Longwall Mining

The mining of a large rectangular block of coal by the longwall method results in the development of a trough- shaped depression of the surface above the extracted area. The process of subsidence is dynamic, as surface move- ment begins with undermining and continues until some maximum displacement has occurred; the magnitude of the

Global Trends in Coal Mine Horizontal Stress Measurements

measurements from U.S. coal mines. The WSM had identified the eastern portion of North America as a stable mid-plate region with a consistent ENE horizontal stress orientation (Zoback and Zoback, 1989). Sure enough, analysis indicated that 75% of the coal mine stress measurement orientations fell within the NE quadrant (Mark, 1991; see figure 1).
