AI Technical Summary
Existing mine backfill control methods are difficult to accurately control the strength distribution of backfill bodies when facing deep and complex geological conditions. In particular, they neglect the influence of temperature field on hydration reaction and the nonlinear law of strength evolution, resulting in unbalanced backfill structure and control lag.
A layered adaptive filling control method based on strength evolution and temperature coupling is adopted. By using discrete time control and the concept of equivalent age, combined with real-time data acquisition from temperature sensors, a composite state vector is constructed. A deep Q-network is used for multi-step look-ahead optimization to achieve precise control and adaptive adjustment of the layered strength of the filling body.
It achieves an overall improvement in the stability of the filling structure, dynamically balances the strength development relationship between the poured layer and the layer to be poured, and solves the control lag and imbalance problems caused by ignoring the nonlinearity of strength evolution and the influence of temperature field in traditional control methods.
