分析导水裂隙带发育高度的影响因素，并提出新的参数即硬岩岩性比例系数，代替顶板岩层单轴抗压强度，避免了现行规范中坚硬、中硬、软弱、极软弱顶板类型划分时单轴抗压强度统计不确定问题，及未反映顶板软硬岩层组合结构问题。以导水裂隙带实测数据为基础，利用回归分析方法分析导水裂隙带高度与各影响因素间的相关关系，通过多元回归分析得到导高与多因素之间的统计关系式，并用于兖矿巨野赵楼矿首采面的导水裂隙带高度预计，为顶板水害预测和防治提供了科学依据。

Analyze the development of water flowing fractured zone height of factors, and put forward a new parameter index namely hard-rock lithology ratio, which insteads of roof strata combination uniaxial compressive strength, avoids to determine statistical problem of u- niaxial compressive strength by the type of hard and medium hard, weak, extremely weak roof in the current specification,and doesn＇t reflect the hard and soft＂ strata combination roof structure. Based on the measured data of water flowing fractured zone, using regression analysis to analyze the relationship between height of water flowing fractured zone and influencing factors, and through multiple regression analysis non-linear statistic formulas are obtained between height of water flowing fractured zone and influencing factors,and used for the expected height of water flowing fractured zone in Yankuang Juye new area Zhaolou first face mining, and provide scientific basis for the prediction and prevention of roof water damage.
