Study on reasonable position of mining roadway under repeated mining overburden structure in shallow buried close distance coal seam: A case study

Puntos clave

• The optimal mining roadway position minimizes subsidence impacts, ensuring better support system effectiveness.
• Findings indicate significant reductions in ground deformation by at least 30% with new positioning techniques.
• Analysis of mining dynamics under repeated overburden structures reveals critical insights into roadway stability.
• These findings highlight the importance of strategic roadway placement in enhancing mining safety and efficiency.
