of predicting mining subsidence for sloping ground surfaces. The results from the above study may be summarised as follows: I. The inclination affects distribution of surface subsidence. Compaœd with the subsidence on the equivalent horizontal surface, thc magnitude of subsidence increases on side and decreases on the up side of the extraction. 2. The rays projection method C an used to ...

As groundwater mining continues, land subsidence and earth fissures will continue to threaten the Arizona public. These geohazards can result in damage to structures designed and constructed to house, serve, and protect the general public as well as public infrastructure including roads, dams, canals, bridges, and utilities. A few specific examples of damage and human safety threats are ...

In reference to mining, subsidence results from the settling of strata overlying the void left underground from the extraction of a valuable mineral or fuel. The impact of surface subsidence in Pennsylvania, and all of the United States, due to underground mining has long been recognized as detrimental to life and property. However, it was only recently (mid1960's) that detailed research in ...

Mine subsidence is the movement of the ground that can occur after underground coal mining. After coal is extracted from beneath the ground, the land above can sink and fill the hollow mine workings. This can cause tilts and strains on the ground surface. Subsidence caused by old inactive mines in New South Wales is generally localised and only ...
