What is Strata Control Monitoring in Contiguous Seam Mining about?

The document describes a study on strata control monitoring during depillaring in a contiguous coal seam mining operation. It includes instrumentation to measure induced stresses on pillars and roof-floor convergence in galleries and junctions with distance from the goaf edge. Higher convergence was observed in junctions compared to galleries, and junctions further from the goaf edge experienced more convergence. Convergence and stresses were generally higher in the bottom seam than the top seam.
