摘　　要：为了得到彬长矿区巨厚砂岩含水层下综放开采导水裂隙带高度,采用数据分析的方法研究了矿区内17组工作面导水裂隙带高度实测数据,得到了彬长矿区导水裂隙带高度计算的回归公式,并基于彬长矿区雅店矿ZF1403工作面地质条件,采用数值模拟和现场实测的方法对回归公式的适用性进行了验证。结果表明:经验公式与实测数据的结果相差较大,已不能作为彬长矿区导水裂隙带高度计算的参考公式,而回归公式计算结果与数值模拟和现场实测的结果基本吻合,回归公式应用效果良好。在矿区内矿井未实测导水裂隙带高度的情况下,回归公式计算结果可作为矿区内矿井导水裂隙带高度的参考。In order to obtain the height of water-conducting fissure zone in fully mechanized caving mining under extra-thick sandstone aquifer in Binchang mining area,the measured data of the mining area within 17 set of working face water fractured zone height are analyzed,and the regression formula of the mining area’s water fractured zone height is obtained,and based on the geological conditions of ZF1403 working face of Yadian Mine in Binchang Mining area,the applicability of the regression formula was verified by numerical simulation and field measurement.The results show that there is a big difference between the empirical formula and the measured data,and the empirical formula can not be used as the reference formula for calculating the height of the water-conducting fracture zone in Binchang mining area,while the calculation results of the regression formula are basically consistent with the numerical simulation and field measurement results.The calculation results of regression formula can be used as a reference for the height of water-conducting fissure zone in the mining area when the measured data is not available.
