英文摘要	Backfill mining, an underground coal mining technology, can mitigate mining-induced hazards and eco-geological environmental problems by regulating the relationship between the water flowing fractured zone height (WFFZH) and the backfill body compression ratio (BBCR). In this study, using the #15,210 working face in the Hongliulin colliery of the Yushenfu mining area as a case study, the influence mechanism of different BBCRs on WFFZH is firstly qualitatively analyzed. Generally, greater BBCR values meant lower WFFZHs and a lower mining activity on the surface eco-geological environment. Subsequently, considering the complex variability of WFFZHs developed in overlying rock-soil composite structure strata, two research methods were adopted: theoretical analysis and numerical simulation. BBCR values of 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, and 10% were used for analysis. With changing of BBCR, on the basis of defining the development eight horizon of the water conducting fracture zone, the WFFZH developed in the bedrock layer was investigated using theoretical analysis, while the WFFZH penetrating through the bedrock into the soil layer was numerically analyzed. Then, combined with the zoning thresholds for environmental engineering geological patterns (EEGPs), the BBCR and EEGPs regulatory relationship was illustrated, and an optimal BBCR for conservation of the eco-geological environment was determined. Finally, comparing the economic benefits of coal mining and filling cost with an optimal BBCR, the economic and social benefits under the optimal BBCR were analyzed. These research results provide a theoretical basis for achieving a win-win strategy that balances the protection of the eco-geological environment and the exploitation of coal resources, promoting the sustainable development of coal mining.
