Current status and progress on the estimation of mining-induced building damage

To meet the urgency and necessary of mining induced building damage estimation in practice，the present situation of the determination of critical deformation and damage classification to building was analyzed.The advantages and shortcomings were investigated for the building damage assessment based on the fuzzy mathematics，matter element，neural network，entropy weight，fuzzy clustering and point method.The new progresses in the assessment of mining induced building damage，such as vulnerability curve，classification and regression tree，were introduced in detail.The study results reveal that it is helpful to improve the accuracy of building damage assessment based on building typology and computer aided analysis.The influences of uncertainty from estimating factor may be further avoided in the process of damage assessment.The areas for further study in the future are proposed.
