    Influence of shallow mine-workings on crack failure of overburden strata
    (Wydawnictwa AGH, 2005) Yu, Xueyi; Huang, Senlin
    Coal exploitation in Shendong mining area in Shaanxi province of China is based on shallow mine-workings, which is the main reason for surface subsidence. A great deal of analysis and research indicates that the crack damage is controlled by the key stratum in the overburden strata. The paper studies the relationship between the stability condition of the key stratum structure and the mining damage, supplying the theoretical evidence for implementing an effective mining method to protect the environment in Shendong mining area.
