[This paper presents a statistical prediction of the height of water flowing fractured zone due to coal mining under sea area. Some field measurement methods were used in the Beizao, Liangjia, Wali and Huangxian Coalmines in Shandong Province, China, to investigate the failure process and the maximum height of water flowing fractured zone under different mining and geological conditions. Then, a statistical method has been adopted in this paper for accurately predicting the height of the water flowing fractured zone from the field measurements. The results show that the height of water flowing fractured zone Hf is mainly determined by cutting thickness of seam m in a non-linear relationship, which can be expressed as \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ H_{f} = 58.26 \cdot (1 - e^{ - 0.3m} ) $$\end{document}.
