Abandoned mine lands (AML) subsidence is one of the most hazardous problems for personal property and community development. In order to improve the technique for subsidence diagnosis and the effectiveness of remedial measures, several methods and techniques have been developed in this research. A subsidence site investigation checklist is developed to guide the investigators with or without hands-on experience to collect a complete and necessary information for subsidence analysis during site investigation. A subsidence cause identification system is developed to streamline the process of analysis and for subsidence cause differentiation and identification over AML. A damage severity system is developed to evaluate the intensity of the damage to structures. A subsidence deduction model is developed based on the probability function integration method to reconstruct subsidence profile and subsurface failure zone for AML subsidence. The study is based on the case studies which include site investigation, surface subsidence survey, subsurface instrumentation, damage severity evaluation, subsidence deduction and statistical analysis. The results show that geologic conditions such as seam depth, seam height, ratios of strong and weak rocks do affect the subsidence damage area, subsidence factor, and damage severity. The relationship between above parameters can be expressed by a second order polynomial with correlation coefficients ranging from 0.7 to 0.9.
