摘　　要：高家堡煤矿4煤顶板分布多个含水层,且其中洛河组含水层富水性强,造成井下注水试验法等方法难以进行导高观测。以高家堡煤矿101工作面为例,利用水质分割法得到工作面出水的水源组成,初步得到101工作面的导水裂缝带高度大于160 m;利用工作面洛河组水量计算中非完整井公式中影响深度L特定含义,得到了导水裂缝带高度与出水量的关系,再根据实际出水量计算出实际导水裂缝带最大高度为178.54 m,裂采比为21.6。通过与彬长矿区其他矿井的实测资料进行对比等方法分析认为该计算方法是可靠的。There are multiple aquifer seams in ground strata over No.4 coal seam in Gaojiapu coalmine.Among them,the Luohe formation aquifer seam has good water yield property,which cause difficulties to observe the height of water conducting fractured zone by some common methods such as water injection testing.Taking 101 working face in Gaojiapu coalmine as an example,this paper applies water quality classification method to determing the water composition flowing from aquifers into mining zone and estimates the height of water conducting fractured zone is over 160m.Moreover, using the special meaning of influence depth "L"in the non-complete well formula in Luohe formation water inflow calculations,the relationship between the height of water conducting fractured zone and the water inflow.Based on the real water flow quantity,the real height of water conducting fractured zone is up to 178.54m,and ratio of water conducting fractured zone height to mining height is 21.6.By comparing real data to other coal mines in Binchang coal field,it proves these calculation methods are reliable.
