采煤导水裂隙带发育高度计算公式概述

Brief Review on the Calculation Method for Height of Water-flowing Fractured Zone

导水裂隙带发育高度是采煤安全的主要影响因素之一,对水体下采煤的矿井水害防治有重要影响,需要对导高进行预测。通过查阅文献,对导高计算经验公式进行了总结,分析了常用的公式形式,为今后导高预测公式研究提供参考。

The height of water-flowing fracture zone is one of the main factors that affect the safety of coal production, especially for the prevention and control of mine water hazards under water body. Therefore, engineering applications need to predict the height of waterflowing fracture zone. By literature, this paper summarizes the empirical formulas and analyzes the commonly used formula forms, which will provide reference for the future study of the height of water-flowing fracture zone prediction formula.
