Verification of Various Surface Subsided Results with Surface Subsidence Theories. Caving and subsidence of rock strata by wall type mining. (2nd Report).

Shigen-to-Sozai, 2000
The author elaborated the results of studies on Surface Subsidence in various coal fileds in Japan(Kushiro), England(NCB collieries) and Republic of South Africa (Sigma). Firstly, the author analysed the sphere at goaf area where fallen rock debris solidified at bottom part while upper rock strata deteriorated by cracking caused by earth pressure.
