The abundance of quantitative roof convergence measurements systematically recorded in Australian mines is distinctly different to all other major coal-producing countries, including the USA, South Africa and China. The literature review identified that no industry-wide research using this data source had yet been completed; nevertheless, roof failure still posed severe safety risks to coal mine workers and commercial risks to corporations. This thesis therefore had two objectives: (i) collate an extensive, novel, industry-wide ground control database fixated on tell-tale measurements, and (ii) complete statistical analyses on this database to investigate ground response in various geotechnical environments. Real-world displacement measurements from more than 80,000 locations at 22 Australian longwall mines were collected, and Python scripting was applied to transform this data into a query-friendly SQL database.
