摘 要:为了探讨东滩煤矿63_(上)06工作面突水水源,基于水化学角度分析了该水源可能的主要充水含水层水化学场变化特征,选取了研究区19个水样(3砂水3个,侏罗系红层水3个,三灰水3个,其它工作面采空区水6个和63_(上)06工作面出水4个)进行对比研究。通过Piper三线图解分析了这5种水的水化学类型,并利用毫克当量及其主要典型离子相应的比值确定了该工作面突水水源。结果表明63_(上)06工作面突水的水质类型和典型离子毫克当量比值均和其它工作面采空区的基本一致,主要是顶板3砂水和侏罗系红层水的混合水通过采空区后流出,但和单独的3砂水、侏罗系红层水及三灰水均具有明显的差异性。研究结果对该工作面突水水源判别和防治具有很好的参考价值。In order to study the No.63upper06 working face goaf water inrush source,the hydrochemical fields of the main water aquifer of the water sources were analyzed,select the Dongtan coal mine 19 water samples(roof sandstone water of the No.3 coal seam 3,Jurassic red strata sandstone water 3,No.3 limestone water 3,other working face goaf water 6 and 63up06 working face goaf water 4).The hydrochemical types of the five types of water were analyzed by Piper three-line diagram and the source of water inrush from the working face was determined by the corresponding ratios of milligram equivalent and its main typical ions.The results show that the water quality type and typical ionic milligram equivalent ratio of water inrush on working face 63up06 are basically the same as those of other working face goaf,it is mainly the mixed water of roof sandstone water of the No.3 coal seam and Jurassic red strata sandstone water that flows out after passing through goaf,but there are obvious differences with single roof sandstone water of the No.3 coal seam,Jurassic red strata sandstone water and the No.3 limestone water.The research results have good reference values for mine water inrush source identification.
