Abstract

The average thickness of the main mined 3# coal seam in a Shandong mine is 8.5m. According to the mine’s future production succession plan, the 7-1 working face will be mined next. The minimum bedrock thickness in this area is only 22 m, increasing the threat of water and sand inrush from the Quaternary loose layer. To avoid induced water and sand inrush disasters during shallow roadway excavation and construction, and to ensure construction safety, this study analyzes the mining conditions, geological conditions, and hydrogeological conditions of the fault-affected thin-bedrock coal roadway. By integrating analytical methods and numerical calculations, the overlying strata failure height after roadway excavation is comprehensively determined. A water prevention and control safety evaluation of roadway excavation is conducted, achieving safe excavation.
