| Abstract: | The mechanism of mining-affected subsidence and overlying strata and ground movement induced by mining of great mining depth and thick seam with strip-partial mining has been studied.The rationality and reliability of strip mining plan and parameter selection has been proved by similar material test simulation in the 25 mining area of Hebi nine coal mine.The damage process of overburden strata,the laws of movement and deformation are found out.The influencing factor and changing law of strip pillar decrement and surface subsidence coefficient has been studied. |
