A powered roof support protects people and equipment in the longwall from potential danger posed by the surrounding rock mass. The study to determine the position of the powered roof support was conducted in an active longwall. The research team made measurements of the geometric height of the powered roof support structure located in the longwall complex. The main objective of this study was to determine the position of the powered roof support in actual underground conditions. The analysis of the results provided data on whether the assumed height of the longwall was maintained during operation of the complex.
