Mining at the Metropolitan Colliery commenced in the 1880s. Modern longwall mining of the Bulli Seam commenced in 1995 with some 15 longwall panels having been completed to date. Coal extracted from the underground mining operations is conveyed to the coal processing and rail loading facilities at the pit top in Helensburgh.

phasis is on coal mining. The time to plan for subsidence impacts is well before mining begins, not after surface effects are noticed. Because subsidence due to underground mining may be inevitable, the relevant questions to be asked are how much, when, and where, and what abatement procedures are possible and might be necessary.

Surface subsidence due to underground mining operation

Jun 01, 2015 Cave-in due to mining operation often occurs at shallow mining depth, especially this phenomenon occurs remarkably during the rainy season. In the case that the longwall mining operation is conducted at relatively deep mining depth, the subsidence basin is formed at the surface (Peng and Chiang, 1984), as shown in Fig. 5. If the magnitude of

However, with the termination of mining operations, the probable completion of most caving, and the stabilization of mine pool levels, major subsidence due to past coal mining has abated since the late 1960's. Subsidence is not expected to be a significant factor in the West Pittston levee project.
