AI Technical Summary
Existing technologies lack scientific theoretical research on the strength design of downward horizontal layered hexagonal approach filling bodies, resulting in highly subjective and insufficiently scientific design methods. This makes it difficult to achieve effective connection between the filling body and the artificial false roof, affecting the stability of the mining area and increasing filling costs.
A strength model for hexagonal infill bodies was constructed using the Schwartz-Christopher multi-angle mapping theory and complex variable function solution method. Through mapping functions and stress analysis, the tensile and compressive strengths of the infill bodies were designed to ensure their stability under different stress states.
It provides a precise basis for the design of backfill strength, avoiding insufficient or excessive strength, ensuring the safety of mining operations, and reducing backfill costs.
