👉 Relief engineering is a critical aspect of structural design focused on managing and mitigating the effects of overburden pressure, particularly in underground mining and civil engineering projects. It involves creating and maintaining safe spaces within structures or excavations to prevent collapse due to excessive stress or load. This is achieved through various techniques such as installing supports, designing drainage systems, and constructing overburden or backfill materials to distribute weight evenly. The goal is to ensure the stability and safety of structures like tunnels, mineshafts, and embankments, thereby minimizing risks to workers and the environment while optimizing resource utilization and operational efficiency.
