Study on the Mechanical Properties of Gangue Filling
Abstract：Through the physical and mechanical experimental analysis of the relationship between different gradation of gangue compac- tion, strain and broken expand coefficient and stress, and making curve fitting of the collected data, the regression formula of three fac- tors changing with the stress is obtained, which provides important reference basis for minimizing surface subsidence and ensuring the optimization of mine coal gangue filling effect.
